What are your OS, Python and Pillow versions?
- OS: Termux
- Python: 3.7.2
- Pillow: 5.4.0
I think the error happens in the function _find_library_dirs_ldconfig, where the executable "/sbin/ldconfig" is called. This executable does not exist on Termux, making the function return None.
[...]
args = ['/sbin/ldconfig', '-p']
[...]
null = open(os.devnull, 'wb')
try:
with null:
p = subprocess.Popen(args,
stderr=null,
stdout=subprocess.PIPE,
env=env)
except OSError: # E.g. command not found
return None
[...]Previous versions can be installed without a problem (as long as the necessary dev packages are installed).
