I'm using node version 12.20.2 and npm version 6.14.11 and installed truffle with cmd as administrator, the truffle framework version 5.5.12 has been installed but when I run any command in the vs code, it pops up with an error

PS E:\Testing (roughf work)> truffle version

I don't know what to do with this

Answer 1

On the truffle quickstart, it states to use nvm , as permission errors like this will occur. However, to solve this error, you can also use this powershell command Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
