Noticed this issue too because Webstorm is using this command to know the available things that generate can do. This issue seems to only exists on @angular/cli==1.6.6; because when i downgrade to @angular/cli==1.6.5 the issue doesn't occur anymore.

denofevil · 2018-01-28T12:35:37Z

Dennis from WebStorm team here. I can confirm that this fails with the same output for me. We'll be releasing WebStorm 2017.3.4 with a workaround (loading predefined list if the command fails), but would love to get a proper fix.

chriskyndrid · 2018-01-28T19:21:08Z

@denofevil, also experiencing the issue with 1.6.6. Thanks for your efforts on the workaround. @h-bex thanks for reporting the issue.

raven1152 · 2018-01-30T19:56:10Z

I also noticed this due to the interaction with WebStorm. Actual generate commands still seem to work, and top level help seems to work, as does help on other commands... just not for the generate command.

kayvanbree · 2018-01-31T11:20:06Z

Same here on 1.6.6 in Webstorm. Updated Angular CLI because of another bug, so I'll have to manually (cmd) generate my components for now.

Flash1232 · 2018-02-01T08:06:18Z

Is this fixed in 1.6.7?

This is not fixed in 1.6.7:

I'm getting the same issue whenever I type "ng g --help"
