angular - 执行启动脚本失败

Question

Angular :5.0.1/
Angular CLI:1.5.0/
节点:8.9.1/
npm: 5.5.1/
操作系统:win32 x64

在终端/命令提示符中执行“npm start”时出现以下错误。谁能帮我解决这个问题？我花了一整天的时间试图修复它，但没有运气。

这是我的 package.json 的脚本部分

"scripts": {
    "start": "webpack-dev-server --inline --progress --port 8080"
  },

webpack.config.js

Answer 1

它应该做到

npm cache clean --force

npm install

npm start
