关于Mac下安装时 Python Imaging Library(Pillow) 报错 error: could not create '/Library/Python/2.7/site-packages/olefile': Permission denied的解决方法之一：

报错详情：(格式调整了一下，以便浏览)

在 Stackoverflow 上查到相关类似报错，error: could not create '/Library/Python/2.7/site-packages/xlrd': Permission denied,
观察之后发现跟权限有关, 其中这个答案：

Try python setup.py install --user

You shouldn't use sudo as suggested above for two reasons:

You're allowing arbitrary untrusted code off the internet to 
be run as root
Passing the --user flag to python setup.py install will install 
the package to a user-owned directory. 
Your normal non-root user won't be able to
access the files installed by sudo pip or sudo python setup.py

比较赞， 于是：

$ pip install Pillow --user

解决问题。
