下面是截图：
我认为错误是由Python包造成的。我更新了python并再次尝试，但无济于事。
什么是错误，请问我该如何解决？
答
这为我工作。
sudo apt-get install python-pip
sudo pip install --upgrade pip
看起来我已经安装并升级了python。
我记得之前尝试过，但它没有奏效。我不知道为什么，但它现在起作用了。
如果有人能说出错误背后的原因并划定解决方案，那将会很有帮助。
答
你试过了吗？
sudo pip install -U os-testr
答
在你的命令行：
sudo apt-get install python-pip
sudo pip install --upgrade pip
sudo pip install -U os-testr
这个工作对我很好......
不，我没有尝试过更早。我今天跑了，但它给了我一个错误。在我成功安装后（请参阅我的回答），您的命令运行良好，但是我已经达到了目的，所以我在中间停止了它。感谢您的贡献。 :) – Nikhil
