如何在Ubuntu 14.04中正确更新请求

Question

我目前正在使用一个依赖于2.7.0或更高版本请求的python包,但我系统中的请求Ubuntu 14.04是版本2.2.1.我试图通过pip升级:

 pip install requests==2.7.0

但它给了我一个错误,说:

Not uninstalling requests at /usr/lib/python2.7/dist-packages, owned by OS

我试图通过使用升级它apt-get install --only-upgrade python-requests,但它说它已经在最新版本(并且它不是).

然后我尝试在虚拟环境中安装,但它提供的信息与上面的pip消息相同.

最后,我想到了两个选择:

1-)通过apt-get卸载然后通过pip安装 - 我认为它太冒险了,因为它会卸载很多其他软件包.

2-)从github克隆并通过setup.py手动安装,但我也担心它可能会混乱其他软件包,具体取决于它

最好的方法是什么？我有什么简单的遗失吗？

我想知道为什么您的OS / Ubuntu请求版本是2.2.1，而我的版本是2.0.1。您是否通过官方python-requests .deb软件包以外的其他机制手动安装了较新版本的请求？如@wilbur在上面的评论中所建议的，您是否有可能sudo pip install requests在过去某个时候跑步过？如果是这样，那么值得一试sudo pip uninstall requests，看看是否可以摆脱它...
