What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

no source code

./node_modules/.bin/eslint

What did you expect to happen?
anything other than crash. Happens when initializing the ESLint probably. Started after the 7.8.0 release.

What actually happened? Please include the actual, raw output from ESLint.
crashed with a stack trace

Thanks for the report.

Looks like related to eslint/eslintrc#1
Fix here: eslint/eslintrc#2

[CallMeFoxie]

Yup adding globals to dependencies seems to have fixed it! Thanks!

[maxymczech]

Confirm, I have same problem after updating to 7.8.0, some sort of conflict in versions of globals. Thank you for the fix!
