Bug#977232: babeljs-node is unable to find system modules

[Pirate Praveen]

Package: node-babel7
Version: 7.12.9+~cs150.130.99-1
Severity: important

When trying to run mocha using babeljs-node command, it fails to find
the modules installed in global nodejs directories.

/usr/bin/mocha -R spec
internal/modules/cjs/loader.js:638

Once I manually set the NODE_PATH variable, it starts working. We
should probably set these paths before calling babeljs-node command.


pravi@mahishi:~/forge/js-team/node-window-size$ export
NODE_PATH=/usr/lib/nodejs:debian/tests/test_modules:/usr/share/nodejs:/usr/lib/x86_64-linux-gnu/nodejs/:/usr/share/nodejs/mocha/node_modules

/usr/bin/mocha -R spec

Some other things I found in this experiment,

1. node-environment-flags module which is required in
/usr/share/nodejs/@babel/node/lib/babel-node.js is only available in
/usr/share/nodejs/mocha/node_modules

2. Also node-yargs is missing a dependency on node-define-property.

So this was a problem with my local environment. I had nvm setup with a
different node executable. After removing ~/.nvm I can find these
modules.

But the following is still an issue,

This should be a bug against node-yargs though. Cloned as separate bug.

Hi,

node-yargs never depends on define-property:

$ npm i --package-lock-only --ignore-scripts
$ grep define-property package-lock.json || echo Not found
Not found

Tried also with previous versions
