Warning: React version not specified in eslint-plugin-react settingsについて
eslintを実行して「Warning: React version not specified in eslint-plugin-react settings」というメッセージが表示される場合は.eslintrcに"settings"->"react"->"version"を追加します。
$ npx eslint src/App.tsx Warning: React version not specified in eslint-plugin-react settings. See https://github.com/yannickcr/eslint-plugin-react#configuration .
.eslintrc.jsonの場合
{ ... (その他の設定) ... "settings": { "react": { "version": "detect", // React version. "detect" automatically picks the version you have installed. // You can also use `16.0`, `16.3`, etc, if you want to override the detected value. // It will default to "latest" and warn if missing, and to "detect" in the future } } }
