That’s why we discourage users to change their default directory structure. (more discussions at https://github.com/vuejs/vue-cli/issues/3040 and https://github.com/vuejs/vue-cli/issues/3061) It would be a tremendous burden for us to deal with all the possible customizations. As in this case, it is because the eslint plugin assumes a default list of files to lint, and none of them exists in the project: https://github.com/vuejs/vue-cli/blob/ddfdd1af2492b2f7bbcbb537d0f35c1ef67d53a0/packages/%40vue/cli-plugin-eslint/lint.js#L55-L70

A simple fix is to just add a second argument for the lint command:

yarn lint web
