Tutorial on installing Python's Pillow library on Mac OS, pythonpillow

Today, I made a python tool for my friend and found that the ptyhon support library is missing in the system. The following information is returned:

ImportError: No module named PIL
Then download and install it. Because there is no python management tool pip on the machine, install it together.
1. Install pip

sudo easy_install pip 

You can directly install pil or pillow after pip is installed successfully.

2. Run pip install pil

pip install Pil 

Downloading/unpacking Pil  Could not find any downloads that satisfy the requirement Pil  Some externally hosted files were ignored (use --allow-external Pil to allow). Cleaning up... No distributions at all found for Pil Storing debug log for failure in /Users/macbook/Library/Logs/pip.log 

3. Install pillow.

pip install --use-wheel Pillow 

Downloading/unpacking Pillow  Downloading Pillow-2.4.0.zip (6.5MB): 5.0MB downloaded Cleaning up... 

When I get it back, I find that the download is not complete. This is a slow process, so I gave up.
4. Git

Download source code https://github.com/python-imaging/Pillow through git

git clone https://github.com/python-imaging/Pillow.git 

Then start compilation and Installation

4.1

python setup.py build_ext -i 

After compilation, you will be prompted to run the test example and find JPEG support not available.

To check the build, run the selftest.py script. 

4.2 an error is reported when running python selftest. py because JPEG support not available.

1 tests of 57 failed.

So I had to uninstall pillow.

You can run the pip command to uninstall the SDK.

pip uninstall pillow sudo pip uninstall pillow

After successful installation, you must install libjpeg support.
