Build nodejs Fail with exit status 126 - Permission denied

Question

I faced a issue when I do a npm start in my linux server.

It is showing error with exit code 126 and permission denied.

I have already done chmod 777 to server.js or rather to the whole folder of demoTest.

How do I fixed this?

The log is shown as below.

Answer 1

I was getting this same issue when running a Nodejs server and Reactjs client. This process worked for me and should be done in the affected directory (I think that's demoTest for you):

1. Delete node_modules
2. Run npm install to reinstall the dependencies in that directory's package.json

I believe this problem started when I copied node_modules from my host to my Ubuntu server rather than running the installs directly from the server CLI.
