Angular:5.0.1 / 角度CLI:1.5.0 / 节点:8.9.1 / npm:5.5.1 / Os:win32 x64

执行" npm start"时出现以下错误在终端/命令提示符下。谁能帮我解决这个问题?我花了一整天的时间试图修复它而没有运气。

这是我的package.json

的脚本部分
"scripts": {
    "start": "webpack-dev-server --inline --progress --port 8080"
  },

webpack.config.js

    })

});

这是错误

4 个答案:

答案 0 :(得分:1)

它应该成功

npm cache clean

npm install

npm start 

答案 1 :(得分:0)

我发现了一种更简单的方法。放弃" npm start"和webpack方法一起使用angular-cli。使用angular-cli,调用" ng build --prod"处理一切(等等)。在幕后,它使用webpack,但它处理所有涉及的复杂问题,因此开发人员不必这样做。

答案 2 :(得分:0)

我只是通过验证和清除缓存,然后将npm更新为最新版本,解决了这个问题。

npm cache verify
npm install
npm start

答案 3 :(得分:0)

如果npm clean cache --force npm install npm start对您不起作用。尝试重命名根文件夹。这对我来说非常有用。
