pytz installation works, but requires user to make build folder manually

[wwoods]

When starting from a blank buildozer installation, if pytz is in the application's requirements, then the user will be faced with an error:

[INFO]:    Building pytz for armeabi-v7a
[INFO]:    pytz apparently isn't already in site-packages

This may be worked around by manually creating the missing build directory:

mkdir .buildozer/android/platform/python-for-android-master/build

After this, buildozer will work (took more than one subsequent invocation for me). Ideally, this manual step should not be needed.

I'm not sure what's wrong here, maybe it's actually a buildozer error.

[wwoods]

Seems like it might be, shall I open the issue there instead?

[youpsla]

I haven't this issue with new buildozer toolchain and python2. But I had to install tzlocal which raise (when the app is on the android phone) the following error:
OSError: [Errno 2] No such file or directory: '/etc/localtime

Closing as stale, please reopen if still a current issue.
