testcafe Command failed: "npm

I installed testcafe globally and it was working with no issues, then I decided to install testcafe locally upon which it said it couldn't find npm in the node modules folder of my project. Then I installed npm locally and it started working again. After a while a decided to delete the local one and use the global but now that's broken and it keeps looking for the one in my local projects folder?!?! So if I then install npm in my local project again I get the following error:

Error: Command failed: "npm

Error when npm isn't installed in my local project:
