Process finished with exit code 126 when trying npm run dev code example

Example: verbose stack Exit status 126

I was getting this same issue. This process worked for me and should be done 
in the affected directory. Follow these Steps:

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.
