jpm breaks with node 7+

[schalkneethling]

When running jpm with Node 7+, jpm breaks with the following error:

$ jpm --version
module.js:472
    throw err;
    ^

Error: Cannot find module 'internal/fs'
    at Function.Module._resolveFilename (module.js:470:15)
    at Function.Module._load (module.js:418:25)

When running against 6.9.4, jpm works but, the following warning is output in the terminal:

(node:36785) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.

What version of npm did you install it with?

[kumar303]

In both cases it seems like it could be an npm bug (of which there are many). Try doing this in each Node version:

npm uninstall -g jpm

Upgrade npm, then run:

npm install -g jpm

It works with version 6.9.4 but, anything 7+ throws the error from above. I did do the uninstall and reinstall as well but, with version 7+ it does not work.

Most likely wrong installations.

$ node --version && npm --version && jpm --version
v7.4.0
4.0.5
1.2.2

@schalkneethling It would be helpful if you post the log of npm install -g jpm

@yan12125 At this point it is working so, I am going to close this and will reopen with more info should I run into the problem again.

To be honest, it might have something to do with updating node via npm g

I have now switched to nvm and so far, so good. Thanks!

@schalkneethling thanks for the bug report! Sorry about the hassle.
