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

时间：2021-03-26 15:13:32

标签： angular npm-start

我经常收到这个错误，如果我删除了项目然后再次下载它然后它就可以工作了，但是在重新启动我的电脑后又出现了同样的错误。

我的全局 angular 版本和项目 angular 版本是一样的。

如果我删除节点模块并重新安装软件包它可以工作，但每次这样做都是浪费时间。

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。

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npm start或ng serve

让我知道这是否有效。

发生这种情况可能是因为您使用的是 node 的更新版本。尝试将您的节点版本降级到 12.11.x or later minor version。

这可能不是 node、npm 或 angular 的问题，

  • 当节点安装在我的 SSD 但我的项目中时出现问题 在我的硬盘中，将我的项目带到 SSD 后，它解决了错误， 现在每次我都不需要通过删除 节点模块。
