I researched a lot on the subject, but I couldn't find a viable solution to my problem, I'm setting up a development environment by NVM I installed node 8.9.0, I managed to install the NPM package on it and the grunt libraries I needed, however, now I'm trying to do the same procedure, but in version 4.4.0 and it doesn't work, any command I give in version 4.4.0 doesn't return any errors
I already tried all the steps in this tutorial: How to completely remove node.js from Windows but it didn't solve my problem either
on another clean machine I installed node 4.4.0 before version 8.9.0 and it worked normally, but it seems that having installed version 8 before version 4 generated this problem
