错误运行子进程时发生错误 cordova

Question

I have finished a project, and I would like to build an apk. I have tried to build it, but after writing the sentences to build it, the third code gave me an error. Here the code or sentences I wrote to be built it.

ionic cordova platform remove android
ionic cordova plarform add android@6.4.0
ionic cordova build android

I have built a project 3 day ago following the code I wrode above. Here the error. ( this time I connect with firebase)

Platform android already added.
[ERROR] An error occurred while running subprocess cordova.

        cordova platform add android@6.4.0 --save exited with exit code 1.

        Re-running this command with the --verbose flag may provide more information.

Answer 6

I encountered this error, and I reinstalled Cordova:

npm uninstall -g cordova
npm install -g cordova

And it works on my side. There are other reasons for this error, so I am not sure this will work on your side.
