I found the problem and expect help somebody. I just run

我发现了这个问题并期待帮助某人。我跑了

npm install android-versions --save

in the project folder and worked.

在项目文件夹中工作。

#2

Not sure if this will help some other Ionic developers, but I was getting the same Error: Cannot find module 'android-versions' and I fixed it by removing and adding the Android platform again:

不确定这是否会帮助其他一些Ionic开发人员，但我得到了相同的错误：找不到模块'android-versions'，我通过删除并再次添加Android平台来修复它：

ionic cordova platform remove android --save

And then

接着

ionic cordova platform add android --save

#3

If anyone is having this issue while using yarn and even after adding android-versions... it seems that there are differences in yarn/npm files which break...

如果有人在使用纱线时遇到这个问题，甚至在添加了android-versions之后...似乎在纱线/ npm文件中存在差异而导致...

I ended up removing my node_modules folder, then installing it with npm instead of yarn. It worked!

我最终删除了我的node_modules文件夹，然后用npm而不是yarn安装它。有效！
