报错信息
--- PLACEHOLDER PACKAGE ---
This @babel/plugin-proposal-private-property-in-object version is not meant to
be imported. Something is importing
@babel/plugin-proposal-private-property-in-object without declaring it in its
dependencies (or devDependencies) in the package.json file.
Add "@babel/plugin-proposal-private-property-in-object" to your devDependencies
to work around this error. This will make this message go away.

一共报了164个类似的错误，都是插件依赖异常
然后今天上午退回了开发者工具的版本 退到 Stable 1.06.2503300 再次运行 完美解决 一个错误都没有
+1,这工具真是一言难尽...
把微信开发者工具卸载，重现去官网下载最新版本的开发者工具就没事了
上周才正常运行的，没有升级开发工具啊，现在也报这个错误了！！！
