Question

我正在安装预装了python 2.7.6的远程linux服务器。我想升级到python 2.7.12 （因为我无法在2.7.6上安装一些库，因为下面显示了一些 ssl错误）。

我从源代码下载并编译并安装了2.7.12并且python2.7打开了2.7.12。但是，在使用pip时，我仍然会收到更新python版本警告。似乎pip没有与2.7.12同步并且继续服务于2.7.6并且我无法在系统中找到其他pip安装。

我只想要一个python2.7.x的工作版本，pip / pip2 / pip2.7正常工作。

Answer 1

以这种方式升级（并自动重新安装）：

/path/to/python2.7.12 -m pip install pip --upgrade

-m标志加载相应的模块，在pip的情况下将执行pip（感谢the power of the __main__ module inside the package）。

安装后，您当前的pip也应该是最新的。

或者，您可以运行

/path/to/python2.7.12 /path/to/pip2 install pip --upgrade

注意：警惕您正在运行的pip和python2：其中可能是/usr/bin/python和/ usr / bin / pip {{1应该在标准系统更新后更新/ usr / local / next to the ones you installed in / usr / bin`，如果有的话。

感谢@Evert，在我尝试解决您的解决方案之前，

curl -O https://bootstrap.pypa.io/get-pip.py
python27 get-pip.py

这解决了我的问题，我可以使用2.7.12

将库安装到pip/pip2.7

我之前尝试python2.7 -m pip install package-name而我正在pip not found。

Python和Pip不同步
