Execution Policy Error in npm

Have you ever encountered an error when trying to run the npm install command, also known as npm i, and the process simply doesn’t work as expected?

This type of problem is more common than it seems and can arise for several reasons, such as incorrect environment configurations, system permissions, or even issues related to conflicting dependencies. In this article, we will explore the most common causes of this error and, most importantly, how to fix it so you can get back to development without any more issues.

This happens due to the PowerShell execution policy settings. Here is a step-by-step guide to resolve the problem:

🔧 Step-by-Step Guide to Fix the Issue:

1- Open PowerShell as Administrator:

● Search for "PowerShell" in the Start menu.

● Right-click on "Windows PowerShell" and select "Run as administrator."

2-Change the Execution Policy:

In PowerShell, type the following command to allow the execution of scripts:

Set-ExecutionPolicy RemoteSigned

Press "Enter" and, when prompted, type "Y" to confirm the change.

3- Check the Execution Policy:

To make sure the change was applied correctly, run the following command:

Get-ExecutionPolicy

It should return the RemoteSigned policy, which allows local scripts and remote scripts that are signed to run.

4- Run the npm install Command Again:

Now, you can try running the command again:

npm create vite@latest

This should resolve the script-blocking issue and allow the installation to complete successfully.

Reverting to the Default Policy (Optional):

If you prefer to revert the execution policy to the more secure default after the installation, just run the following command:

⚠️ Important: Always be cautious when changing the execution policy. Only run scripts from trusted sources. To revert to the default policy, use the following command:

🚨 The last command npm create vite@latest is only needed if you are using vite.
