在Webpack中启用源映射

Question

我对源地图有问题。它们已生成但显然未使用。 我使用webpack-dev-server，反应热模块替换和Webpack v3.x，如果这很重要的话。 在我的webpack-config里面，我使用devtool：＆＃39; source-map＆＃39;我像这样运行我的脚本：

"webpack": "cross-env NODE_ENV=development webpack-dev-server -d --config webpack.config.js"

我得到的错误示例

当我点击此客户端时？e36c：157它不会带我到源代码但是：

如果我从webpack.config中删除devtools并从脚本中删除-d标记，我会得到相同的输出

**webpack.config.js**

const path = require('path')
const webpack = require('webpack')

const publicPath = path.resolve(__dirname, './src/client')
const buildPath = path.resolve(__dirname, './src')
// const BrowserSyncPlugin = require('browser-sync-webpack-plugin')
const Write = require('write-file-webpack-plugin')

process.noDeprecation = true
