ionic build Android | error: No installed build tools found. Please install the Android build tools

Question

When I run ionic build android command in root of ionic project, I am getting this error:

FAILURE: Build failed with an exception.

Answer 1

I have tried all the above solution. None works. Until I was linked to https://forum.ionicframework.com/t/ionic-v4-no-installed-build-tools-found/152150.

Apparently, you must run the command as root. Sudo is not enough. You need to change to root user before you can run all the commands.
