Angular 无法执行启动脚本

角度：5.0.1/ Angular CLI:1.5.0/ 节点：8.9.1/ 净现值：5.5.1/ 操作系统：win32 x64

在终端/命令提示符中执行“npm start”时，我遇到以下错误。有人能帮我解决这个问题吗？我花了一整天的时间试图修好它，但运气不好

这是我的包的脚本部分。json

它会成功的

npm cache clean --force

npm install

npm start 

---

我发现了一种更简单的方法。完全放弃“npm启动”和webpack方法，使用angular cli。使用angular cli，调用“ng build--prod”处理所有事情（aot等）。在幕后，它使用webpack，但它处理了所有涉及的复杂问题，因此开发人员不必这样做。

我只是通过验证和清理缓存，然后将npm更新到最新版本来解决这个问题

npm cache verify
npm install
npm start

---

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。它对我来说非常有效。

你能分享你的

webpack.config.js

文件吗？我现在已经和webpack.common.js、webpack.dev.js和webpack.prod.jsnpm一起分享了它。干净的缓存不起作用。它返回可用的npm使用命令。npm cache clean将返回此“截至”npm@5，npm缓存自修复损坏问题，并保证从缓存提取的数据有效。如果要确保所有内容一致，请改用“npm缓存验证”。我尝试了消息中所述的“npm缓存验证”，然后是“npm启动”，但问题仍然存在。尝试：npm缓存清理--强制否，我没有先删除节点\ U模块。。。。我现在已经删除了node_模块，并重新运行命令“npm clean cache--force”、“npm install”，最后是“npm start”。这个问题仍然存在。这实际上是可行的，我在react native中遇到了类似的问题，这很有效，谢谢
