已成功卸载：
第一步：安装pip，终端里sudo -i输入密码后，输入easy_install pip:
1:~ root# easy_install pip

第二步：卸载pycrypto(我把输入错误的命令也写上来了，不要笑)
1:~ root# pip uninstall -r
Usage:
pip uninstall [options]
...
pip uninstall [options] -r
-r option requires an argument
1:~ root# pip uninsatll -r pycrypto
ERROR: unknown command "uninsatll" - maybe you meant "uninstall"
1:~ root# pip uninstall -r pycrypto
Could not open requirements file: [Errno 2] No such file or directory: 'pycrypto'
1:~ root# pip unistall -y pycrypto
ERROR: unknown command "unistall" - maybe you meant "uninstall"
