`npm edit @scoped/package` incorrectly parses slash in package name

What I Wanted to Do

Wanted to use npm edit to quickly make changes to a locally-installed package. A scoped package in this case. I expected the command to open ./node_modules/<@scoped/package> in a new editor window.

What Happened Instead

The package installed to ./node_modules/@scope/name, but npm edit tries to open ./node_modules/@scope/node_modules/name

❯ npm edit @atlaskit/media-card                                                                                                                   387ms  Mon Sep 17 17:05:13 2018

Reproduction Steps

  1. local npm install any scoped package
  2. try to use npm edit to open that package in an editor


npm/cli/lib/edit.js doesn’t know how to handle the slash that is in all scoped package names.

function edit (args, cb) {
  var p = args[0]
  if (args.length !== 1 || !p) return cb(edit.usage)
  p = p.split('/')
    .replace(/(\/node_modules)+/, '/node_modules')

Also occurs with node 10.10.0 and npm 6.4.1.

I am just going to use npm link for now, probably a better idea anyway.
