What Operating System are you using?

Linux

[NeuralFault]

It's because npm needs access to bash shell and can't get it from within the environment due to isolation.

Go to SM Settings > Package Environment section> Environment Variables and click Edit.

Click the + button to add a row and put this in for the two sections:

Name: PATH

Value: /usr/bin:$PATH
