WP CLI theme install. Install a private repo?
I actually figured out a way to do this. First you use wget like this: wget –user username –ask-password -O path/to/output.zip https://bitbucket.org/path/to/file.zip the -O flag specifies output and output.zip is where you want it to download to. Then you can run: wp theme install path/to/output.zip –activate Happy days
