Solution

This error occurs when your system has disabled the running script and your system is can’t accept the ng commands. This error occurs due to security reasons and won't let the script be executed on your system without your approval. Then you have to open the PowerShell with administrative rights.

To solve this problem, you need to follow a few steps:

Step 1

First, you have to need to open the command prompt and run this command.

set-ExecutionPolicy RemoteSigned -Scope CurrentUser

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.

Now you have to go to the next step.

Step 2

Now you have to run the second command on your system. This command is:

Get-ExecutionPolicy

When you have run this command your system has a show "RemoteSigned". If you have received this message, then your problem will be solved. Now you have to go to the next step to view the list of policy which policy has been updated by the last commands.

The image will be shown as below:

Step 3

To view their policy, you need to run this command in your command prompt:

Get-ExecutionPolicy -list  

When you run this command, a few policies are shown on your monitor screen. These policies are:

Scope ExecutionPolicy
----- ---------------

MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser RemoteSigned
LocalMachine Undefined
CurrentUser RemoteSigned
LocalMachine Undefined

Now you can see your system execution policy list. You have successfully solved your problem. Now you need to go to the command prompt and check that your problem is solved.

Now I run an ng command in my command prompt. This command is "ng --version". To check my CLI version. When I run it, the ng command the output will be shown like this:
