ESLint couldn't find the plugin "eslint-plugin-<%- pluginName %>". This can happen for a couple different reasons: 1. If ESLint is installed globally, then make sure eslint-plugin-<%- pluginName %> is also installed globally. A globally-installed ESLint cannot find a locally-installed plugin. 2. If ESLint is installed locally, then it's likely that the plugin isn't installed correctly. Try reinstalling by running the following: npm i eslint-plugin-<%- pluginName %>@latest --save-dev If you still can't figure out the problem, please stop by https://gitter.im/eslint/eslint to chat with the team.
