Question

我尝试关注https://www.tutorialspoint.com/reactjs/reactjs_environment_setup.htm以便在我的设备中设置具有Ubuntu 16.04的reactJS。

最后我尝试了npm start但是它导致我跟踪错误

> reactjs@1.0.0 start /var/www/html/reactjs
> webpack-dev-server --hot

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.output.path: The provided value "./" is not an absolute path!

Answer 1

有史以来最直接的错误消息。

你不能在输出中使用相对路径（我不记得以前版本的webpack中是否可以）。 Docs

output: {
   path: require('path').resolve(__dirname, './path/to/build/folder'),

Answer 2

使用 create-react-app 创建新的reactjs应用程序。

只需删除node_modules文件夹，然后使用npm install重新安装npm包。
