python - 在 Msys 上安装 Pip

Question

我已经使用 Python 3.5.2 和 Msys 构建了一个简单的 PyGTK 应用程序，但我需要一些不在默认安装中的模块，虽然我可以使用 setup.py install 来获取它们，但我非常愿意而是使用 pip。

我环顾四周，发现 this但它与 Python 2 相关，并在尝试按照给出的说明进行操作时出错:

$ python3 getpip.py

我尝试了在 Linux 上安装 pip 的方法:

pacman -S python2-pip           
pacman -S python-pip           

如所列here ，以及:

pacman -S python3-pip

但每次我都收到一个error: target not found:错误。

令人惊讶的是我找不到其他任何东西。

那么如何在 Msys 上获取 pip 呢？

谢谢。

Answer 1

请注意，此时以下命令正在 msys2 上运行:

$ pacman -S python3-pip
$ pip3 install --upgrade pip
