How To Solve “nodemon.ps1 cannot be loaded because running scripts is disabled on this system” In NodeJs

“Nodemon.ps1 cannot be loaded because running scripts is disabled on this system” is a common error related to the unsafe Windows policy. The below explanations can help you know more about the cause of error and solutions.

How does the error “nodemon.ps1 cannot be loaded because running scripts is disabled on this system” happen?

This error happens due to the many following reasons:

First, it might be because running scripts is disabled on this system, as the execution policy has banned running the given script in Windows. To check this, run Powershell as administrator and run:

get-ExecutionPolicy

Output:

Restricted

Second, it’s safe if you allow running remotely signed scripts on the computer. This means you can run unsigned local scripts, i.e. scripts you wrote…. Otherwise, scripts run from nodemon (remote source) must have been signed by trusted authorities. If you’re using Windows, open Settings, then choose “Update & Security”. At the “For developers” menu, scroll down to find this check box in the “PowerShell” subheading:

How to solve the error?

Solution 1: Change the current execution policy 

To solve “nodemon.ps1 cannot be loaded because running scripts is disabled on this system” error, you will have to open Powershell as administrator and run this command:

Set-ExecutionPolicy Unrestricted

Or you can use this command to change the current execution policy to RemoteSigned (the default execution policy for Windows server computers) instead of Unrestricted, this will change the policy to the CurrentUser if possible:

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Now you can check again to see execution policy changes with this command

Get-ExecutionPolicy

You should get 1 of 2 following outputs: 

Unrestricted
RemoteSigned

Solution 2: Change execution policy to allow local Powershell scripts to run without signing

If you’re using Windows 10 or 11, open Settings and choose Update & Security:

Click “For Developers” in the left sidebar and at the PowerShell subheading. Tick option:

Solution 3: Delete the nodemon.ps1 file

Go to this location in you computer:

C:\Users\Your_name\AppData\Roaming\npm

Then delete the file named nodemon.ps1 and restart the terminal. Now run the code again to check if you had succeeded:

nodemon 'code.js'

If you caught the same error, you should try cleaning npm cache and then rerun the above code:

npm cache clean --force
