Commands don't work in vscode powershell terminal

I am getting an error similar to this when I try to execute any command in the terminal in vscode. Does anyone know how to solve this problem?

pip : The term 'pip' is not recognized as the name of a cmdlet, function, 
script file, or operable program. Check the spelling of the name, or if a 
path was included, verify that the path is correct and try again.
