在Mac OS系统上安装Python的Pillow库的教程-Python教學-PHP中文網

今天帮朋友做个python的小工具，发现系统上缺少ptyhon的支持库，返回如下信息

ImportError: No module named PIL
然后就下载安装,因为机器上也没有python的管理工具pip，所以也一并安装
1. 安装pip

sudo easy_install pip

登入後複製

pip 安装成功就可以直接安装pil或者pillow

2. 通过命令pip install pil

pip install Pil

登入後複製

3. 所以就安装pillow

弄了会别的回来发现还没有下载完，这叫一个慢呀，于是放弃
4. Git

通过git下载源码地址https://github.com/python-imaging/Pillow

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

然后开始编译安装

4.1

python setup.py build_ext -i

编译完之后会提示运行测试例子，并且发现JPEG support not available

4.2 因为JPEG support not available，运行python selftest.py报告错误

1 tests of 57 failed.

于是只好卸载pillow

可以通过pip命令来卸载

pip uninstall pillow 
sudo pip uninstall pillow
