angular - npm start (angular 11) 抛出错误（未知错误：SyntaxError: Unexpected token '*'）

问题描述

我经常遇到这个错误，如果我删除了项目然后再次下载它就可以了，但是重新启动我的电脑后再次发生同样的错误。

我的全局角度版本和项目角度版本是相同的。

如果我删除节点模块并重新安装它可以工作的包，但每次这样做都是浪费时间。

解决方案

似乎有些软件包没有安装。您需要安装软件包，然后尝试运行该应用程序。

尝试以下步骤。

  • 进入项目目录
  • 删除 npm_modules 目录
  • 清理 npm 缓存npm cache clean --force
  • 验证缓存npm cache verify
  • 安装依赖项npm install
  • 运行应用程序npm start或ng serve

让我知道这是否有效。
