Pillow安装出错

安装环境：win7 64 但是我的python是32bit

>>错误：

C:\Users\XS>cd E:\Study_project_all\Python_study\pyQt4_GUI\rj
C:\Users\XS>pip install Pillow-2.7.0-cp27-none-win_amd64.whl

=============================报错=========================================

e file does not exist
Pillow-2.7.0-cp27-none-win_amd64.whl is not a supported wheel on this platform.

>>后来改用32bit

C:\Users\XS>pip install Pillow-4.3.0-cp27-cp27m-win32.whl

>>终于找到原因！是因为路径没有切换成功！！！路径没设置对

路径是安装包Pillow-4.3.0-cp27-cp27m-win32.whl

应该先

E:\>cd E:\Study_project_all\Python_study\pyQt4_GUI\rj

E:\Study_project_all\Python_study\pyQt4_GUI\rj>pip install Pillow-4.3.0-cp27-cp27m-win32.whl
