I have tried downgrading ESLint to 4.3.0 and it solves the problem. So I guess it's related to the latest release of ESLint.

@mysticatea seems like this is an issue with vue-eslint-parser not eslint-plugin-vue

https://github.com/mysticatea/vue-eslint-parser/blob/43932bf50bd057cdbd316f25eacd92288312e8f7/src/parser-services.ts#L24

@ctf0 @riophae ok i see where there is issue eslint property from context was renamed to private
this._linter = linter;

[riophae]

@ctf0 It's already released: https://github.com/vuejs/eslint-plugin-vue/commit/a1fd26be58b657af9aa3f11acb191a172df0e233

[armano2]

@ctf0 you have to update eslint-plugin-vue to version 3.11.0
