Can't install on raspberry pi 3b+

[bourbourg]

Hi,

I tried to install on my raspberry pi but it can't finish the following command:
sudo pip install chdkptp.py

I get this error:
Failed to build wheel for chdkptp.py
and then:
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-e68krr/chdkptp.py/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-record-nAn0pP/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-install-e68krr/chdkptp.py/

The first error is
Building wheels for collected packages: chdkptp.py Running setup.py bdist_wheel for chdkptp.py ... error Complete output from command /usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-e68krr/chdkptp.py/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/pip-wheel-sJZ9Zd --python-tag cp27:

@bourbourg make sure that Lua and libusb installed, or install sudo apt install lua5.2-dev libusb-dev

This error is probably because the patch command fails. I get this when I try to install it from source
