https://developers.weixin.qq.com/miniprogram/dev/devtools/stable.html 在5010正常运行的代码，到5020的工具上不行了 报了一堆这样的错 [] Error: file: common/vendor.js --- 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.
