Error installing PIL library for Python

Question

After installing xcode I executed pip install Pillow and the last code strings say:

In file included from _imagingtk.c:19:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/tk.h:78:11: fatal error: 'X11/Xlib.h' file not found

Answer 1

The actual problem is that Xcode's Command Line Tools is missing. To fix it, just run

xcode-select --install

on your terminal. A dialog will pop up, accept and Xcode's CLT will be installed.

See it here .

Answer 2

PIL is deprecated, use Pillow instead.

To install Pillow:

 pip install Pillow

Answer 3

Did you uninstall PIL first?

Try:

pip uninstall pil
pip uninstall pillow
brew install libtiff libjpeg webp little-cms2
pip install pillow

See https://pillow.readthedocs.io/en/stable/installation.html for more information.

Answer 4

Install XQuartz .

X (or X11 ) is a (the default) *nix window system, which some *nix software that can be compiled on a Mac relies upon.

The problem appears to be that PIL and Pillow appear to assume you want Tk(inter) , which in turns relies on X . If you don't want fancy dialog stuff for your image processing, there should be a way to turn that off, though that may require a manual installation.

Alternatively, perhaps this answer may be of use; but that still requires X to be installed, and just fixes a bad link.

Answer 5

Installing SDK headers worked for me

sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /
