Workaround to use NPM install for Node.js application in Plesk

If upgrading the server does not resolve the issue, our Support Engineers have another workaround to get the job done.

1. First, we have to connect to the server through SSH.
2. Next, we will change the affected path in /opt/plesk/node/12/lib/node_modules/npm/bin/npm-cli.js as well as other files to the correct one. For instance, here is an example for NodeJS 12:

   # find /opt/plesk/node/12 -type f -print0 | xargs -0 sed -i -e 
   '1s,#!/usr/bin/env node,#!/opt/plesk/node/12/bin/node,g' 
   -e '1s,^#!\s*/usr/bin/python($|\s),#!/usr/bin/python2\1,' 
   -e '1s,^#!\s*/usr/bin/env\s+python($|\s),#!/usr/bin/env python2\1,'
