cd test123
ng lint

-> all ok

add "no-unnecessary-qualifier": true and "promise-function-async": true to tslint.json

ng lint --type-check

The log given by the failure.

Warning: Cannot read property 'exports' of undefined
Warning: Cannot read property 'flags' of undefined
Warning: Cannot read property 'members' of undefined

Desired functionality.

No warnings.

Mention any other details that might be useful.

When I use webpack 2.3.1, tslint 4.5.1 and codelyzer 2.0.1 without angular-cli I get no warnings with this rules.

Sounds like a bug alright, thanks for the report!

I get this warning when using tslint-loader in a Webpack project, but there's no Angular involved. Seems harmless. At least I haven't noticed what effect it has, if any.

[pgrm]

ng lint seems to work, just ng lint --type-check shows those errors. Also when I run tslint directly (even with --type-check I don't get those warnings

I see

Warning: Cannot read property 'some' of undefined

when enabling no-unnecessary-qualifier rule. I'm running tslint directly. tslint 5.1.0, codelyzer 3.0.1. Maybe it is related to this one.

I'm also confirming that I don't see the (maybe-related) issue with no-unnecessary-qualifier. I don't remember exactly if it was fixed by upgrading tslint to 5.2, but it was some component upgrade that fixed this warning.

[Martin-Wegner]

Yes it seems bo be fixed.
