ng build help shows incorrect flag options #1934
Description
Please provide us with the following information:
- OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
Max OS X, although I imagine that's not relevant. - Versions. Please run
ng --version. If there's nothing outputted, please run
in a Terminal:node --versionand paste the result here:
1.0.0-beta.11-webpack.8 - Repro steps. Was this an app that wasn't created using the CLI? What change did you
do on your code? etc.
If you run ng build --help, you see as one option:
--environment (String) (Default: development)
aliases: -e <value>, -dev (--environment=development), -prod (--environment=production)
If you then run this
ng build --environment=production
you get "Path must be a string. Received undefined".
If you do ng build --environment=prod, it works. I'm assuming this is because there's an src/environments/environment.prod.ts file but not src/environments/environment.production.ts.
Seems like the help output should be corrected and you should get a friendlier error if you provide a bogus environment value.
- The log given by the failure. Normally this include a stack trace and some
more information.
