I was having the same problem and I found the following solution:

<ol>
<li>remove both of

<ul>
<li>%ProgramFiles%\nodejs\npm</li>
<li>%ProgramFiles%\nodejs\npm.cmd</li>
</ul></li>
<li>Go into %ProgramFiles%\nodejs\node_modules\npm and copy the file named npmrc in the new npm folder, which should be %appdata%\npm\node_modules\npm. This will tell the new npm where the global installed packages are.</li>
<li>Restart Windows and it worked. </li>
</ol>

blocks|key|134227|text|我也遇到了同样的问题，在设置node.js之后，我遵循了unix指南的某些部分，最终将我当前的工作目录移到了一个新文件夹中，但我忘记了将.npmrc文件从旧位置复制到新位置。我还将我的前缀的位置从%25AppData%25改为%25AppData%25，这是通过使用npm+config+ls+-l将我的当前设置与默认设置进行比较而找到的。这里的两个线索是，我在开头有一行名为userconfig的行，指向我的.npmrc文件，该文件位于不同的位置，并且我的前缀被默认值覆盖。将其更改回默认设置解决了此问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|134228|尝试将这些重置为默认值，并检查您的配置设置。我不确定重新安装node.js是否会有任何帮助，如果它仍然引用您的旧设置。|134229|entityMap^0|3H|G|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

I had this same problem, after setting up node.js I followed parts of a guide intended for unix and ended up moving my current working directory to a new folder, but I forgot to copy the .npmrc file from the old location to the new one. I also changed the location of my prefix away from %AppData%, which I found by using <code>npm config ls -l</code> to compare my current settings to the default. The two clues here were that I had a line at the start called userconfig pointing to my .npmrc file, which was in a different location, and that my prefix was overridden from the default value. Changing this back to the default fixed the problem. 

Try resetting these to the defaults and check what your config settings are. I'm not sure if reinstalling node.js would help anything if it was still referencing your old settings.

It seems like this kind of error can be caused by a file permissions lock - I experienced something very similar (the same ERRNO: -4048) when installing <code>whatwg-fetch</code>.
I found that a Visual Studio instance I had open at the same time was acquiring all kinds of files which it didn't need. Once I closed that down, the install worked perfectly.

It seems that this error can manifest for more than one reason, so there probably won't be a single fix which works for everyone. 

However, concurrency issues often are the cause of the failing installs. According to the accumulated wisdom in one of the related npm issue threads, which has received nearly 180 comments so far, the <a href="https://github.com/npm/npm/issues/17671#issuecomment-343615800" rel="nofollow noreferrer">underlying problem is</a> 

<blockquote>
 a race condition between asynchronous I/O operations accessing the same files on the harddisk. You can certainly influence it by cleaning up the harddisk e.g. with "npm cache verify" or moving the project to a SSD, but this does not solve the root cause of the problem.
</blockquote>

Likewise, closing the IDE or disabling the virus scanner works sometimes, for some people, but does not really fix the problem for good if concurrency issues are behind it.

A patch has landed in npm 5.6.0. According to initial reports, it seems to do the trick. So if your <code>npm --version</code> is lower, update to 5.6.0 (or whatever the current version is when you read this):

<pre><code>npm uninstall -g npm
npm install -g npm@5.6.0
</code></pre>

as <a href="https://github.com/npm/npm/issues/17671#issuecomment-347968454" rel="nofollow noreferrer">suggested here</a>.

If that doesn't help, then perhaps a file lock is the true cause. And closing the IDE, or disabling the virus scanner temporarily, or some similar action is indeed the way to go, as @Oly has said <a href="https://stackoverflow.com/a/44014485/508355">above</a>.
