Question

我正在使用React和NPM构建一个应用。

我已经像这样设置了package.json

但是当我运行npm start时，控制台中出现以下错误：

Failed to compile.

./src/store/dashboards/reducers.js
  Line 29:43:  Unexpected dangling '_' in '_id'  no-underscore-dangle
  Line 36:36:  Unexpected dangling '_' in '_id'  no-underscore-dangle

我正在使用VS Code，并且更改package.json中的eslintConfig属性似乎适用于IDE，但不适用于运行该应用程序。我还尝试将/* eslint-disable no-underscore-dangle */添加到./src/store/dashboards/reducers.js的顶部。同样，它似乎是向编辑器注册的，而不是向编译器注册的。我还尝试将eslint配置提取到其自己的文件.eslintrc中。仍然没有编译。

Answer 1

@devaent 的解决方案（重新安装node_modules和yarn.lock）起到了很大的作用，但是每次我向{添加另一个规则时，我都必须重新做一次{1}}。

我已经忍受了三天，今天很幸运地找到了另一个解决方案。

在.eslintrc.json的第340行中，如下添加config/webpack.config.js，它对我有用。

useEslintrc: true

我从这篇文章[link]中得到了这个想法。

仅供参考，我在下面分享我的options: { cache: true, formatter: require.resolve('react-dev-utils/eslintFormatter'), eslintPath: require.resolve('eslint'), resolvePluginsRelativeTo: __dirname, useEslintrc: true, // <= added line },。

.eslintrc.json

Answer 2

我能够通过删除/ node_modules /和package-lock.json

解决问题

但是，不幸的是，这个问题不断出现。如果有人有解释，我将接受为答案。

编辑：最终裁决，npm uninstall -g eslint

Answer 3

似乎eslint错误正在破坏构建。您可以通过在webpack.config.js的eslint-loader配置中添加“ emitWarning：true”来禁用它

rm -rf xyz

有没有办法更改退出的create-react-app的陪同规则？
