找不到入口模块和Webpack中的错误

Question

我是JavaScript的新手，请按照Github上的清晰节点教程进行操作。但是无论我在所有模块中尝试过什么，当我运行yarn dev：wds

时，都会不断收到此错误消息。

    ERROR in Entry module not found: Error: Can't resolve './src' in 'C:\Users\Renate\projects'     
    ERROR in multi (webpack)-dev-server/client?http://localhost:8080 ./src Module not found: 
    Error: Can't resolve './src'  in 'C:\Users\Renate\projects'  @ multi (webpack)-dev- 
    server/client?http://localhost:8

我已经尝试过此solution，但是重新安装babel-loader 7并不能解决我的问题。我也尝试过重新安装整个webpack-module，但这也不能解决我的问题。

我的webpack.config.babel.js文件：

// @flow

import path from 'path'
import webpack from 'webpack'

import { WDS_PORT } from './src/shared/config'
import { isProd } from './src/shared/util'

export default {
  entry: [
    'react-hot-loader/patch',
    './src/client',
  ],
  output: {
    filename: 'js/bundle.js',
    path: path.resolve(__dirname, 'dist/'),
    publicPath: isProd ? '/static/' : `http://localhost:${WDS_PORT}/dist/`,
  },
  module: {
    rules: [
      { test: /\.(js|jsx)$/, use: 'babel-loader', exclude: /node_modules/ },
    ],
  },
  devtool: isProd ? false : 'source-map',
  resolve: {
    extensions: ['.js', '.jsx'],
  },
  devServer: {
    port: WDS_PORT,
    hot: true,
    headers: {
      'Access-Control-Allow-Origin': '*',
    },
  },
  plugins: [
    new webpack.optimize.OccurrenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NamedModulesPlugin(),
    new webpack.NoEmitOnErrorsPlugin(),
  ],
}

我的babelrc.json文件：

并且如果您查看此Github页面或this，您会发现还有更多的问题相同，但到目前为止，没有解决方案对我有用。希望你能帮助我！

更新

我也尝试过亚历克斯（Alex）的建议（请参见下面的答案），但没有用。

    ...
    entry: [
       'react-hot-loader/patch',
       path.resolve(__dirname, './src/client')
       ],

    ...

Answer 1

只是一个建议：您是否曾尝试解决有问题的路径，然后再将其传递到webpack？大致思路是：path.resolve(__dirname, './src/client')会将路径从相对转换为绝对，并且通常可以使各种装载机静音。

...
  entry: [
    'react-hot-loader/patch',
    path.resolve(__dirname, './src/client'),
  ],
