easy_install pip使用上述命令重新安装一下pip就好了
easy_insall的作用和perl中的cpan,ruby中的gem类似,都提供了在线一键安装模块的傻瓜方便方式,而pip是easy_install的改进版,提供更好的提示信息,删除package等功能。老版本的python中只有easy_install,没有pip。
easy_install的用法:
1) 安装一个包
$ easy_install <package_name>
$ easy_install "<package_name>==<version>"
2) 升级一个包
$ easy_install -U "<package_name>>=<version>"
pip的用法
1) 安装一个包
$ pip install <package_name>
$ pip install <package_name>==<version>
2) 升级一个包 (如果不提供version号,升级到最新版本)
$ pip install --upgrade <package_name>>=<version>
3)删除一个包
$ pip uninstall <package_name>
