3. 所以就安裝pillow

Cleaning up...

弄了會(huì)別的回來(lái)發(fā)現(xiàn)還沒(méi)有下載完，這叫一個(gè)慢呀，于是放棄
4. Git

通過(guò)git下載源碼地址https://github.com/python-imaging/Pillow

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

然后開(kāi)始編譯安裝

4.1

python setup.py build_ext -i

編譯完之后會(huì)提示運(yùn)行測(cè)試?yán)?，并且發(fā)現(xiàn)JPEG support not available

To add a missing option, make sure you have the required 
library, and set the corresponding ROOT variable in the 
setup.py script. 
 
To check the build, run the selftest.py script.

4.2 因?yàn)镴PEG support not available，運(yùn)行python selftest.py報(bào)告錯(cuò)誤

1 tests of 57 failed.

于是只好卸載pillow

可以通過(guò)pip命令來(lái)卸載

pip uninstall pillow 
sudo pip uninstall pillow

成功之后需要安裝libjpeg的支持

brew install libjpeg

安裝成功之后重新編譯pillow
