How to fix error- nodemon.ps1 cannot be loaded because running scripts is disabled on this system, (without security risk)?

Question

Error on terminal: nodemon.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

I have a solution to fix the issue by this way

1. Open Windows PowerShell with Run as Administrator
2. Run this command: Set-ExecutionPolicy Unrestricted

That solves the issue, but this way the system shows Security Risk Warning. My question: Is there any other way to solve this without security risk? Target is to use nodemon.

Solution 1

I'd recommend using RemoteSigned as opposed to Unrestricted, and limiting the policy to the CurrentUser if possible.

Run Powershell as Admin, and then:

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

RemoteSigned: "The default execution policy for Windows server computers."

---

Other than that, I wouldn't worry about it too much, as it's not intended to be a security mechanism. See this quote from the docs:

"The execution policy isn't a security system that restricts user actions. For example, users can easily bypass a policy by typing the script contents at the command line when they cannot run a script. Instead, the execution policy helps users to set basic rules and prevents them from violating them unintentionally."

Solution 2

For those who are not aware of how to solve this error using Windows PowerShell

1. Open PowerShell (Run As Administrator)
2. Check the current execution policy using this command

    Get-ExecutionPolicy
    # You should get 'Restricted'

3. Run this command to make it 'Unrestricted'

    Set-ExecutionPolicy Unrestricted

4. Check again whether execution policy changed by running this command

    Get-ExecutionPolicy
    # You should get 'Unrestricted'

5. Now try to run nodemon on your project

    nodemon 'filename.js'

Hope this would be helpful

Solution 3

Step 1 : Go to this location --> File C:\Users\Dell\AppData\Roaming\npm
Step 2 : Delete the nodemon.ps1 file and run the command.

Solution 4

There is no security risk whatsoever associated with allowing remoted signed scripts to run on your local machine. It basically means you can execute local unsigned scripts i.e scripts written by you while scripts from a remote source (nodemon in this case) must be signed by a trusted authority.

P.S: If you're on windows, you can just go to settings >> update and security >> for developers >> check the box beside change execution policy to allow local powershell scripts to run without signing

Solution 5

This command might help

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Setting the execution policy to Unrestricted is unnecessary and non-optimal in this case, and is kind of a footgun.

That worked for me and the serve is working with localhost:5000

This doesn't answer the question. At all.

Is there anyway to set this policy by command promt?

[derekbaker783]

@TommyHoang, run CMD as admin, then: cmd.exe /c powershell -command Set-ExecutionPolicy RemoteSigned

Noticed there are two scripts there. One is a cmd script while the other is a powershell. With the powershell script deleted, it will default to the cmd script but you will notice a very minimal delay which is not noticeable persay
