ng new fails if there is a node_modules directory with angular-cli in the parent dir.

[MikeWay]

Please provide us with the following information:

1. OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
   Win 10
2. Versions. Please run ng --version. If there's nothing outputted, please run
   in a Terminal: node --version and paste the result here:
3. Repro steps. Was this an app that wasn't created using the CLI? What change did you
   do on your code? etc.

1. Slightly unusual in that I'm tryin to share a single node_modules across multiple projects so have node_modules in the parent directory of the one I'm trying to create the project in (created previously with the same versions and moved to the parent directory). (I create projects with --skip-npm = true then create a symlink).

2. Failure occurs using ng new XXXXX

3. Workaround is to rename the node_modules in the parent project. The revert node_modules name and create symlink which works fine.

Dir structure

// root / myFolder / node_modules ----< Renaming this temporarily is the work around
/ DoNows -- Run ng new in here
/ XXXX -- created OK once node_modules renamed

1. The log given by the failure. Normally this include a stack trace and some
   more information.

Thanks! We'll be in touch soon.

Hm, this has to do with how the global CLI finds the local CLI. Still the errors shouldn't be so obscure.

Additional report for the same bug:

OS?

OS X El Capitan 10.11.6 (15G1004)

Versions.

angular-cli: 1.0.0-beta.16
node: 4.4.7
os: darwin x64

Repro steps.

Situation:

• ng installed system-wide as symlink: /usr/local/bin/ng -> ../lib/node_modules/angular-cli/bin/ng
• standing in a very empty directory /tmp/foobarproject
• ng just works (the bare ng shows the help - Usage: ng <command (Default: help)> and so on)
• The angular-cli is also installed system-wide in /usr/local/lib/node_modules/angular-cli/

Steps:

• Run $ npm install angular-cli, this creates node_modules direcotry with angular-cli in it, plus ~950 others (dependencies)
• Run ng, it fails

This was my first painful experience with the ng command :-(
