I get the following error message:
*bytes, CFIndex length, CFAllocatorRef bytesDeallocator);
^~~~~~~~~~~~~~~~~~~~~~~~~~~
error: command 'gcc' failed with exit status 1
I used this command:
"//anaconda/bin/python -u -c "import setuptools, tokenize;file='/private/var/folders/sg/p9ztjwgx1v1cctrr2hmdymcr0000gp/T/pip-build-y_mai_3m/kivy/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /var/folders/sg/p9ztjwgx1v1cctrr2hmdymcr0000gp/T/pip-_3c7ty_r-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /private/var/folders/sg/p9ztjwgx1v1cctrr2hmdymcr0000gp/T/pip-build-y_mai_3m/kivy/
What could be the reason, how to solve this problem?
