应用程序崩溃 - 启动前等待文件更改答案

【问题标题】：app crashed - waiting for file changes before starting应用程序崩溃 - 启动前等待文件更改

【问题描述】：

当我运行 gulp 命令时，我的 reactjs 项目中出现此错误。该项目显示它编译成功，但 nodemon 应用程序崩溃，因此我无法查看我的应用程序正在运行。

附：我在mac上，当我以前在ubuntu vmware上运行它时，我曾经编译它没有任何错误。

这是我运行 gulp 时的错误

是因为sn-p的第一行吗？还是因为别的什么？我应该如何解决它？我尝试关闭项目并重新打开它，我也尝试了 npm install 再次。

更新：我已经通过将 gulp 版本从 3.9.1 降级到 3.9.0 解决了“无法加载外部模块 @babel/register”。但是 nodemon 应用程序崩溃仍然存在。

是不是因为node版本？我有 9.4.0 节点版本

【问题讨论】：

可以尝试降级您的节点 8.9.4 吗？
这方面也没有进展
当你在浏览器中点击你的应用程序时控制台会说什么？您的 sn-p 中还有弃用警告吗？ --debug 已被弃用？

【解决方案1】：

经过这么多的尝试和尝试，我通过降级我正在使用的节点版本解决了这个问题。我从 9.4.0 降级到 6.9.1，应用程序开始工作。希望这会节省某人的努力。
