    Exception: Unable to find capture version in ./main.py
 (looking for `__version__ = '(.*)'`)

I'm trying to compile a simple probability calculator I designed. I can't post the code, because I'm going to try to publish it. However, I'm willing to answer any questions I need to to get this to work.

Judging by the output of buildozer, I think it's looking for a line in main.py that I didn't know I needed. Unfortunately, I don't have any idea what that line would look like. However, in buildozer.spec, there is a line that says this:

version.regex = __version__ = '(.*)'
version.filename = %(source.dir)s/main.py

The first line looks like the line in the output and the second references the main.py file. Does anyone know what these lines mean? I am new to buildozer, so I'm not quite sure what to do here. Thanks in advance for your help.

解决方案

By default, buildozer looks for a line in your main.py of the form __version__ = 'something'. This is used to set the apk version, a required field.

You can either add this line to your main.py, or comment out the version check and uncomment the alternative version method on the next lines of buildozer.spec. This lets you set the version string in buildozer.spec itself.
