Pillow: Unable to install on macOS Big Sur (zlib missing)

Created on 26 Jul 2020 · 19Comments · Source: python-pillow/Pillow

What did you do?

I am trying to install Pillow (since it's required for matplotlib). I am running macOS Big Sur beta 3 (20A5323l), with Python 3.8.5 installed with homebrew. I also have numpy and zlib installed through homebrew.

When I try to install Pillow with pip, I get the following error:

➜ sudo -H python3 -m pip install --upgrade Pillow

What did you expect to happen?

Pillow will properly install.

What actually happened?

Error message shown above

What are your OS, Python and Pillow versions?

OS: macOS Big Sur (11.0/10.16) Beta 3
Python: 3.8.5 from homebrew
Pillow: attempting to install 7.2.0 (or any version)

What else have you tried?

I followed every solution given in #4242 including downgrading pip, upgrading pip, specifying different Pillow versions, and using easy_install. I have installed, uninstalled, and reinstalled zlib from homebrew.

Run export SYSTEM_VERSION_COMPAT=1 before all other scripts
They say Big Sur is both 10.16 and 11.0. So it's kind of a backward compatibility.

Please could you try some suggestions from https://github.com/python-pillow/Pillow/issues/3438?

Please could you try some suggestions from #3438?

Hmm, none of those solutions seem to apply/do anything. I have CommandLine Tools installed, but I don't have the Packages directory so I can't run sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers.... I already have openssl and [email protected] installed through homebrew, and adding stuff to my LDFLAGS, CPATH, CPPFLAGS, and PKG_CONFIG_PATH doesn't change anything.

I´m also having the same problem

I'm having the same problem today

First, It's a unreleased OS, not publicly available, so the support level is "It might work" until it's out. At that point I expect that we'll have a developer on Big Sur to debug it.

Second, I suspect that the problem is that it's looking for wheels for macosx_11.0, not macos_10.whatevers, so none of the binaries are matching, even though it's likely binary compatible with the catalina compatible wheels. This is probably a pip/packaging issue.

Third, macos has switched library locations and build incantations quite a few times. It's going to take a while for the packaging community to work out what's actually changed here.

The issue here is compiler.include_dirs doesn't have the correct set of paths in it, and thus we aren't finding it.

clang by default is using:

And indeed, /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.0.sdk/usr/include/zlib.h exists.

I believe Catalina had already got rid of /usr/include, so I don't know how/if this worked there?

I've created PR #4842 to try and address this.

If you are interested in testing my PR, you can do so with sudo -H python3 -m pip install https://github.com/radarhere/Pillow/archive/zlib.zip

Yup, that fixes it for me

If you are interested in testing my PR, you can do so with sudo -H python3 -m pip install https://github.com/radarhere/Pillow/archive/zlib.zip

Also fixes https://github.com/python-pillow/Pillow/issues/3438 for me on Mojave (10.14).

First reproduce with master (in a new terminal with no extra env vars set from #3438, and I didn't use sudo in either case):

$ python3 -m pip install https://github.com/python-pillow/Pillow/archive/master.zip

  ERROR: Failed building wheel for Pillow
  Running setup.py clean for Pillow
Failed to build Pillow
DEPRECATION: Could not build wheels for Pillow which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.

It should really be possible to install it against the system Python as well as Homebrew, and that requires the macOS SDK path to be on the set of include paths to search. (I think it also requires something to be fixed to find the library stub in the SDK, but that's in distutils/CPython-land, see https://bugs.python.org/issue41116.)

gsnedders on 18 Aug 2020

4974 is part of 8.0.0, so the SDK path should now be included as well.

The same error, when trying to install latest Pillow on macOS 11.0.1
When trying to use solution above

Don't worry about trying my zlib branch - my PR has been merged and released as part of Pillow 8.0.

Do you happen to know where zlib.h is located on your machine? Do you expect it to be there because of Xcode, homebrew or something else?

radarhere on 13 Nov 2020

I tried it by brew install zlib
brew --prefix zlib returns: /usr/local/opt/zlib
Was no success

Downloading and make from sources & defining PATH variables like mentioned here solve the issue

ComradeLV on 13 Nov 2020

CFLAGS='-I/usr/local/opt/zlib/include -L/usr/local/opt/zlib/lib' pip install Pillow==<version>

worked for me

Run export SYSTEM_VERSION_COMPAT=1 before all other scripts
They say Big Sur is both 10.16 and 11.0. So it's kind of a backward compatibility.

I reinstalled zlib via brew, and then ran the exports that suggested which solved the problem for me:

export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
export PKG_CONFIG_PATH="/usr/local/opt/zlib/lib/pkgconfig"

this is what worked for me, I wanted to highlight it in case others have the same problem (none of the other recommendations did).
