在Msys上安装Pip

Question

我使用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,虽然我可以使用它setup.py install来获取它们,但我更愿意使用它们pip.

我环顾四周找到了这个,但它与Python 2有关,并在尝试按照给出的指示时发出错误:

$ python3 getpip.py

我尝试了pip在Linux上安装的方式:

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

由于上市这里,还有:

pacman -S python3-pip

但每次我收到error: target not found:错误.

令人惊讶的是我找不到任何其他东西.

那么我如何pip上Msys？

谢谢.

Answer 1

请注意,此时以下命令现在正在msys2上运行:

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

Answer 2

接受的答案安装了一个新的 Python 可执行文件pip，但没有 GTK 支持。

为了安装pip对现有 GTK Python 可执行文件的支持，在遇到该错误后，我们需要运行：

python -m pip install -U --force-reinstall pip

（摘自本期）

总结将 Pip 支持安装到 GTK-Python 可执行文件所需的步骤：

1. curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
2. python get-pip.py
3. （忽略上一步的错误）
4. python -m pip install -U --force-reinstall pip
