Issue of AttributeError

The version of NDK is r16c, operated on debian 9.40.
When the command was run, "p4a create --requirement=pil", following error occurred.

Then execution was over.
Is it missing configuration?Or a bug?I remember that this command once succeeded in making a distribution.

[simon2x]

Did you manage to fix this problem? I'm having the same exact issue..

[katcom]

The parameter " --requirement=pil" should be " --requirements=pil ".
I think that it is a the problem caused by typo.

[AndreMiras]

Yes I also got the issue running with buildozer and the problem was the requirements had some kinda syntax error, so same story.
Nonetheless it would be great to have some kind of parsing and argument checking to prevent that.

Hi!
I seem to be having the same issue. I don't think I'm having some sort of syntax error though. Any idea what might be causing the build to fail in my case?

Any help is much appreciated.

[AndreMiras]

Yes you have a syntax error, your requirement line is empty, see that line:

# Run '/usr/bin/python -m pythonforandroid.toolchain create --dist_name=compass --bootstrap=sdl2 --requirements= --arch armeabi-v7a --copy-libs --color=always --storage-dir="/usr/share/kivy-examples/android/compass/.buildozer/android/platform/build"'

Specifically:

--requirements= --arch
