OS.
- Windows 10.0.10586 Pro *. Versions.

$ ng --version                                                                                                                                             
(node:10072) 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. 
angular-cli: 1.0.0-beta.0

Repro steps.
- Tried to add command completion using the step described in the README. I am using non-Admin/Elevated Git Bash.

ng completion >> ~/.bash_profile
source ~/.bash_profile

The log given by the failure.

Mention any other details that might be useful.

Problem persists on 1.0.0-beta.1

$ ng -v (node:40160) 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. Could not start watchman; falling back to NodeWatcher for file system events. Visit http://ember-cli.com/user-guide/#watchman for more info. angular-cli: 1.0.0-beta.1 node: 6.0.0 os: darwin x64

brew install watchman … and … ng completion 2>/dev/null >> ~/.zshrc … did the trick for me.

As watchman is a recommendation for the EmberCli anyway (see https://ember-cli.com/user-guide/#watchman) it makes sense to have it installed for angular-cli also. Maybe it should be mentioned in the CLIs README?

The output piping against /dev/null was needed on my system with node v6.3.1 to get rid of a deprecation warning of graceful-fs.

Fix is coming

I forget to mention about that…It’s the problem with angular-cli…look what ng --version is giving you…!

@ehzShelter Unfortunately ng completion | cat >> ~/.bashrc inserts the following at the bottom of my .bashrc

(node:6472) 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.
[2K[1G[?25h###-begin-ng-completion### 
#
# ng command completion script
#
# Installation: ng completion >> ~/.bashrc (or ~/.zshrc)
#

(With the remainder of the ng command completion script following.)

So this solution would break my .bashrc if I didn’t go in and manually remove the (node:6472) fs... line.
