reactjs - 错误 : Cannot find module 'eslint-config-flowtype'

Question

我正在尝试同时使用 Webpack、ESLint 和 Flow 类型。但是，当我启动 webpack-dev-server 时，我收到以下错误消息。奇怪的是 eslint-config-flowtype 甚至不是 NPM 中的模块。以前有人遇到过这个问题吗？提前致谢!

ERROR in ./src/index.jsx

使用 Create React App 在 Visual Studio 中遇到类似错误，但它是:

(ESLint) Failed to load plugin 'flowtype' declared in 'package.json »eslint-config-react-app': Cannot find module 'eslint-plugin-flowtype

通过安装为全局包解决:npm i -g eslint-plugin-flowtype
