问题
I design websites in VSC and PowerShell is my default terminal.
After updating and deploying a website to firebase earlier, I was prompted to update firebase tools - which I did using npm. Immediately after I cannot run/access any firebase scripts wthout the folllowing error:
firebase : File C:\Users\mada7\AppData\Roaming\npm\firebase.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. At line:1 char:1
firebase
+ CategoryInfo : SecurityError: (:) [], PSSecurityException
+ FullyQualifiedErrorId : UnauthorizedAccess
I've spent a few hours searching around and can't find a solid answer the problem. Many threads are several years old and I find it bizarre I've not had this problem in the past year until today. I can still access firebase scripts if I set my default terminal to cmd.
Assuming the problem was related to firebase-tools I've carried on working but have now updated vue.js and get the error again when trying to run any vue commands in powershell:
vue : File C:\Users\mada7\AppData\Roaming\npm\vue.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. At line:1 char:1

I've been reading around and seen many threads around permissions for scripts, but I haven't changed any - indeed the PowerShell scripts worked right up until I updated my packages. No other settings touched in the mean time. I don't want to be changing PowerShell settings unnecessarily.
回答1:
Just delete firebase.ps1 file:
File C:\Users\<your account>\AppData\Roaming\npm\firebase.ps1
回答2:
This is a powershell security policy, to fix it, run Powershell as administrator and run the following
PS C:\> Set-ExecutionPolicy RemoteSigned
The stricter the policy, the more secure your system becomes.
You can change RemoteSigned to other options like: Restricted, AllSigned, RemoteSigned, Unrestricted

回答3:
- search for powershell
- right click and run as administration
- run this simple command
Set-ExecutionPolicy RemoteSigned - Press A And Enter
回答4:
Also, one thing worth mentioning is that you need to open PowerShell as Admin and then change the policy like so.
PS C:\> Set-ExecutionPolicy RemoteSigned
Reference - Using the Set-ExecutionPolicy Cmdlet
回答5:
A little clarification: when you run PowerShell as Admin, in most cases you don't need to note a path. Just type:
Set-ExecutionPolicy RemoteSigned
then press "A", then "Enter"
回答6:
This could be due to the current user having an undefined ExecutionPolicy.
You could try the following
Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
回答7:
File C:\Users\xxxx\AppData\Roaming\npm\vue.ps1 cannot be loaded because running scripts is disabled on this system.
I had the same error message with vue. After running the below command successfully
npm install -g @vue/cli
when i ran commands like vue or vue --version, i received that error message.
This is how i fixed it:
I pressed the buttons windows + E, clicked view, checked hidden items.
Then, i went to C:\Users\xxxx\AppData\Roaming\npm folder and deleted the vue file of type 'windows powershell script'.
After that, i ran the commands vue and vue --version succesfully.
Hope this helps.
回答8:
I don't know if it can help with Firebase but I had a similar problem installing Vue with *>npm install -g @vue/cli* .
Long story short:
I deleted vue.ps1 from C:\Users\XXX\AppData\Roaming\npm\ and installed it locally (without -g) from powershell terminal inside VsCode *>npm install @vue/cli*.
After that I could use Vue commands without problems.
回答9:
I also had this problem in the powershell and i used the following : then i again installed the serve package.
Set-ExecutionPolicy -Scope CurrentUser
and then i chose Unrestricted and gave serve command and it worked.
