我要退出这个 YouTube 视频：

他做了很好的解释，但是当我完成他所做的步骤时，我仍然遇到不同的错误。

解决方案

我遇到了同样的问题，终于找到了一个对我有用的技巧。

  1. 关闭任何与 electron.exe 相关的进程。如果您在 Windows 基础系统上，您可以打开任务管理器并查找 eletron 进程或运行以下命令：

taskkill /im electron.exe /f

  1. 从您的项目中卸载电子 npm 库：

    npm uninstall electron

  2. 再次安装电子：

    npm install electron@latest -D
