You can use <a href="https://github.com/nuget/home" rel="noreferrer">nuget.exe</a> to restore your packages or with NuGet 2.7, or above, installed you can simply compile your solution in Visual Studio, which will also restore the missing packages.

For NuGet.exe you can run the following command for each project.

<pre><code>nuget install packages.config
</code></pre>

Or with <a href="https://learn.microsoft.com/en-au/nuget/tools/cli-ref-restore" rel="noreferrer">NuGet 2.7 you can restore all packages in the solution</a> using the command line.

<pre><code>nuget restore YourSolution.sln
</code></pre>

Both of these will pull down the packages. Your project files will not be modified however when running this command so the project should already have a reference to the NuGet packages. If this is not the case then you can use Visual Studio to install the packages.

With NuGet 2.7, and above, Visual Studio will automatically restore missing NuGet packages when you build your solution so there is no need to use NuGet.exe.

To update all the packages in your solution, first restore them, and then you can either use NuGet.exe to update the packages or from within Visual Studio you can update the packages from the Package Manager Console window, or finally you can use the Manage Packages dialog.

From the command line you can update packages in the solution to the latest version available from nuget.org.

<pre><code>nuget update YourSolution.sln
</code></pre>

Note that this will not run any PowerShell scripts in any NuGet packages.

From within Visual Studio you can use the <a href="http://docs.nuget.org/docs/reference/package-manager-console-powershell-reference" rel="noreferrer">Package Manager Console</a> to also update the packages. This has the benefit that any PowerShell scripts will be run as part of the update where as using NuGet.exe will not run them. The following command will update all packages in every project to the latest version available from nuget.org.

<pre><code>Update-Package
</code></pre>

You can also restrict this down to one project.

<pre><code>Update-Package -Project YourProjectName
</code></pre>

If you want to reinstall the packages to the same versions as were previously installed then you can use the <code>-reinstall</code> argument with <code>Update-Package</code> command.

<pre><code>Update-Package -reinstall
</code></pre>

You can also restrict this down to one project.

<pre><code>Update-Package -reinstall -Project YourProjectName
</code></pre>

The <code>-reinstall</code> option will first uninstall and then install the package back again into a project.

Or, you can update the packages using the <code>Manage Packages</code> dialog.

There is another, newer and quicker way to do this from within Visual Studio. Check out <a href="http://blog.davidebbo.com/2011/08/easy-way-to-set-up-nuget-to-restore.html" rel="noreferrer">this post</a> by David Ebbo, and reference the comments section if you run into trouble. Basically, you do the following in Package Manager prompt:

<pre><code>PM&gt; Install-Package NuGetPowerTools
PM&gt; Enable-PackageRestore
</code></pre>

Afterwards, when you build your solution the packages will be automatically installed if they're missing.

Update:

This functionality is built into Nuget 1.6 with visual studio integration so you don't even need to install NuGetPowerTools or type commands. All you have to do is 

<blockquote>
 Right click on the Solution node in Solution Explorer and select
 Enable NuGet Package Restore.
</blockquote>

I believe the first thing you need to do is <a href="http://docs.nuget.org/docs/workflows/using-nuget-without-committing-packages" rel="nofollow">enable the package restore feature</a>. See also <a href="http://docs.nuget.org/docs/reference/package-restore" rel="nofollow">here</a>. This is done at the solution (not project) level.

But that won't get you all the way -- I ran into a similar issue after having enabled the restore feature. (VS2013, NuGet 2.8.)

It turned out I had (unintentionally) committed the packages to source control when I committed the project -- but Visual Studio (and the source control plugin) had helpfully ignored the binaries when performing the check-in.

The problem arose when I created a release branch. My local copy of the dev/main/trunk branch had the binaries, because that's where I had originally installed/downloaded the packages. 
However, in the new release branch,

<ul>
<li>the package folders and <code>.nupkg</code> files were all there -- so NuGet didn't think there was anything to restore;</li>
<li>but at the same time, none of the DLLs were present -- i.e. the third-party references were missing -- so I couldn't build.</li>
</ul>

I deleted all the package folders in <code>$(SolutionDir)/packages</code> (under the release branch) and then ran a full rebuild, and this time the build succeeded. 
... and then of course I went back and removed the package folders from source control (in the trunk and release branch). I'm not clear (yet) on whether the <code>repositories.config</code> file should be removed as well.

Many of the components installed for you by the project templates -- at least for web projects -- are NuGet packages. That is, this issue is not limited to packages you've added. 
So enable package restore immediately after creating the project/solution, and before you perform an initial check-in, clear the <code>packages</code> folder (and make sure you commit the <code>.nuget</code> folder to source control).

Disclaimer: I saw another answer here on SO which indicated that clearing the <code>packages</code> folder was part of the resolution. That put me on the right track, so I'd like to give the author credit, but I can no longer locate that question/answer. I'll post an edit if I stumble across it.

I'd also note that <code>Update-Package -reinstall</code> will modify the <code>.sln</code> and <code>.csproj</code>/<code>.vbproj</code> files. At least that's what it did in my case. Which IMHO makes this option much less attractive.

blocks|key|3256043|text|在VS2012+V11，如果我在行尾使用"-Reinstall“，它就不能工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3256044|所以我简单地说：|3256045|Update-Package+-ProjectName+'NAME_OF_THE_PROJECT'|code-block|syntax|javascript|3256046|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

I know this is an old post, but thought this could be useful. If you have a need to ignore specific packages during the update process (like any packages that update JavaScript references), use the following PowerShell script (make sure your package source is set to "All" in Package Manager Console):

EDIT 2014-09-25 10:55 AM EST - Fixed a bug in the script

<pre><code>$packagePath = "packages.config"
$projectName = "MyProjectName"

$packagesToIgnore = @(
 "bootstrap",
 "jQuery",
 "jquery-globalize",
 "jquery.mobile",
 "jQuery.jqGrid",
 "jQuery.UI.Combined",
 "jQuery.Validation",
 "Microsoft.jQuery.Unobtrusive.Validation",
 "Modernizr",
 "Moment.js"
)

[xml]$packageFile = gc $packagePath
$packagesToProcess = $packageFile.packages.package | Where-Object {$packagesToIgnore -notcontains $_.id}

$packagesToProcess | % { Update-Package -reinstall -projectname $projectName -id $($_.id) }
</code></pre>

I'm using visual studio 2015 and the solutions given above didn't work for me, so i did the following:

Delete the packages folder from my solution and also bin and obj folders from every project in the solution and give it a rebuild.

Maybe you will have the next error: 

<blockquote>
 unable to locate nuget.exe
</blockquote>

To solve this: Change this line in your NuGet.targets file and setting it to true:

<pre><code>&lt;DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' "&gt;true&lt;/DownloadNuGetExe&gt;
</code></pre>

blocks|key|1702806|text|对于那些由于构建服务器与此冲突而到达这里的人，您可以创建一个运行exec命令的MSBuild目标来运行nuget还原命令，如下所示(在本例中，nuget.exe位于.nuget文件夹中，而不是路径上)，然后在构建解决方案之前在TeamCity构建步骤中运行。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1702807|<Target+Name="BeforeBuild">

For those arriving here due to the build server falling foul of this, you can create an MSBuild target running the exec command to run the nuget restore command, as below (in this case nuget.exe is in the .nuget folder, rather than on the path), which can then be run in a TeamCity build step immediately prior to building the solution

<pre><code>&lt;Target Name="BeforeBuild"&gt;
 &lt;Exec Command="..\.nuget\nuget restore ..\MySolution.sln"/&gt;

After 3 hours of searching and investigation. 

I had problems with it because we have two members in team (using GitHub source control), because we didn't restrict files for packages for sending to remote repository, one of team members was send packages to server and i have pull that changes to my local. 

After that i had same problem as PO, also i wasn't be able to publish my API project to server.

At the and I have just used 

Update-Package -Reinstall - run this command on Package Manager Console 

This command will reinstall all your packages that you have used in your solution. (For every project)

Reinstall all packages in ALL PROJECTS of the current solution:

Update-Package -ProjectName 'NameOfProject' -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that are in relation with project that you specified after "-ProjectName". And i think that this is better because i had wait for half a hour to reinstall all packages in solution. 

For this many thanks to <a href="https://stackoverflow.com/users/864201/rodolpho-brock">Rodolpho Brock</a>. 

Also, I would recommend you that when you pull changes from remote server, to press "Restore packages" button that will be shown by Visual studio.

In Visual Studio 2017 - When you compile using IDE - It will download all the missing nuget packages and save in the folder "packages".

But on the build machine compilation was done using msbuild.exe. In that case, I downloaded nuget.exe. 

During each build process before executing msbuild.exe. It will execute -> nuget.exe restore NAME_OF_SLN_File (if there is only one .SLN file then you can ignore that parameter).

I tried <code>Update-Package -reinstall</code> but it fails on a package and stopped processing all remaining packages of projects in my solution.

I ended up with my script that enumerates all package.config files and run <code>Update-Package -Reinstall -ProjectName prj -Id pkg</code> for each project/package.

Hope it can be useful for someone:

<pre><code>$files = Get-ChildItem -Recurse -Include packages.config;

[array]$projectPackages = @();
$files | foreach { [xml]$packageFile = gc $_; $projectName = $_.Directory.Name; $packageFile.packages.package.id | foreach { $projectPackages += @( ,@( $projectName, $_ ) ) } }

$projectPackages | foreach { Update-Package -Reinstall -ProjectName $_[0] -Id $_[1] }
</code></pre>

Edit:
This is an error that I had:
Update-Package : Unable to find package 'EntityFramework.BulkInsert-ef6'. Existing packages must be restored before performing an install or update.
Manual run of
<code>Update-Package -Reinstall -ProjectName my_prj -Id EntityFramework.BulkInsert-ef6</code>
worked very well.

Don't know since when, but in VS2019 you can do it in an easier way:

<ol>
<li>right click solution in Solution Explorer</li>
<li>select Manage Nuget Packages for Solution</li>
<li>there are 4 tabs, Browse, Installed, Updates, Consolidate</li>
<li>the Consolidate shows if there is any projects using different version of packages (and in most cases, that's why we want to update all the packages)</li>
<li>the Updates shows if there is any update available in ANY projects. Select all and click update, the job will be done.</li>
</ol>

I have a solution with multiple projects in it. Most of the third party references are missing, yet there are <code>packages.config</code> file for each project. How do I get NuGet to install/update all the packages needed? Does this need to be done via command line for each project?

How do I get NuGet to install/update all the packages in the packages.config?
