"Permission Denied" in Node on Linux, when running start-script /w local nodemon/mocha/babel-node

Question

I'm having issues with my new linux setup - I've installed nodemon as a local dependency (NOT globally) and I'm trying to execute it from my package.json "start"-script. I'm getting this permission error.

node by itself works great, but as soon as I try to use babel-node or nodemon or even mocha, I get permission problems.

My setup is divided across 2 hard drives - node is installed on my SSD (with my OS), and my project (and it's node_modules, where I'm trying to execute nodemon from is on my storage-HDD.

sh: 1: nodemon: Permission denied

Answer 1

I had this problem after changing moving my project from an NTFS filesystem to linux. I changed all the file/directory permissions to 644/755 and also set the owner/group. That's when I started getting this error.

When I tried nodemon in the terminal, I got command not found. Strange.

Reinstalling nodemon fixed it:

sudo npm install -g nodemon

Answer 2

My secondary drive was incompatible with my linux OS in terms of permissions, as it was an NTFS partition.

I ended up moving everything to my primary drive, and of course permissions were working again, allowing me to execute local dependencies.

I guess the solution to my problem, had I relied on keeping projects on the secondary drive, would be to format it to a format compatible with Linux permissions.
