Sorry about the early post, I hit enter when the test field wasn't in focus and logged the bug earlier than I intended. Fixed everything now.

Any more details? Having the same issue on the same standard version.

Looks like @feross is targeting this to be fixed in the next major version of standard (v12)

eslint-config-standard was updated to fix this last month and released as a v12 alpha:
standard/eslint-config-standard@6a89a51

sticking to standard@11.0.1 which uses eslint@~4.1.18 will avoid this for now.

Otherwise switching to directly use eslint-config-standard@12.0.0-alpha.0 would make it go away.

@feross any plans for a standard@next v12 soon? :)

I've tried using eslint-config-standard@12.0.0-alpha.0 as suggested in #1156 (comment) but I'm running into these related issues with peer dependencies:

• standard/eslint-config-standard-jsx#32
• standard/eslint-config-standard-react#48

I'm hoping @LinusU will be able to move this forward!

(see standard/eslint-config-standard#123 (comment))
