Method 1:
Step1:Run the command &quot;Set-ExecutionPolicy RemoteSigned -Scope CurrentUser&quot;
When you run this command, you can see that your system has set all policies for the current user as remotely. It will take few seconds to complete this process.
Step2:enter image description here Get-ExecutionPolicy -list
When you run this command, a few policies are shown on your monitor screen
Verify if policy for current user is RemoteSigned.
-&gt;If YES this should work now.
If NO please try Method 2 as below:
Method 2:
Find the file &quot;ng.ps1&quot; in path C:\Users%username%\AppData\Roaming\npm\ and
remove it from the directory.
if you don't know the file extension then right click on the file-&gt;got to properties and check the extension of file.
Note:-Please do not remove any other file. Make sure you are removing ng.ps1 file only.

blocks|key|2283095|text|此问题可能是由于未设置环境变量造成的。这对我起了作用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2283096|运行：|2283097|npm+uninstall+-g+angular-cli

This issue may be due to the environment variable not being set.
This worked for me:
Run:
<pre><code>npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm install -g @angular/cli
</code></pre>
After installing, you enter Advanced System Configuration -&gt; Environment Variables -&gt; Path -&gt; Edit
If this Angular variable is not in the path, you add:
&quot;C:\Users\youruser\AppData\Roaming\npm&quot;
Close the terminal, open it and run the command again
