PowerShell Execution Policy Restriction

Script cannot be loaded because running scripts is disabled on this system

When I tried to install MySQL using Bun, it threw an error on my Windows machine. I encountered a PowerShell execution policy restriction, which prevented scripts like bun.ps1 from running. Here is the error I got when I tried to add mysql2 using Bun.

bun : File C:\nvm4w\nodejs\bun.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies

✅Solution: Allow PowerShell to Run Scripts Temporarily

Run the following command in PowerShell (Run as Administrator):

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

Your system was blocking the execution of bun.ps1 due to PowerShell's Execution Policy, which is a security feature that prevents untrusted scripts from running. By default, Windows often sets it to Restricted, meaning no scripts can run.

RemoteSigned → Allows running local scripts (like bun.ps1) but requires downloaded scripts to be signed by a trusted publisher.

-Scope CurrentUser → Applies the change only to your user account, not system-wide.

Hope you all understand the issue and are able to fix it.

Thank You!
