Question

我试图在Windows 10计算机上通过MSYS2 Shell安装Jupyter（根据https://jupyter.org/install，“使用pip安装Jupyter”）-进程崩溃；然后我发现了这个：

jupyter notebook fails to start · Issue #1540 · msys2/MSYS2-packages · GitHub

您需要从mingw64 shell（而不是msys2 shell）启动jupyter notebook。对我来说，一个简单的jupyter笔记本可以按预期工作。

好，所以我想尝试MINGW64 shell。

注意，在MSYS2 shell中：

user@DESKTOP-PC MSYS /c/
$ python3 -m pip install --upgrade pip

  Found existing installation: pip 19.1
    Uninstalling pip-19.1:
      Successfully uninstalled pip-19.1
Successfully installed pip-19.1.1

因此，pip在MSYS2 shell中可以正常工作。但是，如果我尝试使用MINGW64：

user@DESKTOP-PC MINGW64 ~
$ python3 -m pip install jupyter
C:/msys64/mingw64/bin/python3.exe: No module named pip

user@DESKTOP-PC MINGW64 ~
$ python2 -m pip install --upgrade pip
C:/msys64/mingw64/bin/python2.exe: No module named pip

注意上面在MINGW64 shell中python的路径；如果我们尝试查看MSYS2中Python的路径是什么，则有所不同：

user@DESKTOP-PC MSYS /c/
$ which python3
/usr/bin/python3

user@DESKTOP-PC MSYS /c/
$ cygpath -w `which python3`
C:\msys64\usr\bin\python3.exe

无论如何-我可以在Windows 10的MINGW64 shell中为pip使用python吗？

编辑：刚尝试在MINGW64中使用python3安装pip-不起作用：

user@PC MINGW64 /c/Users/user/Desktop
$ python3 get-pip.py

Answer 1

对于Mingw-64，pip会在程序包的下游进行修补。要安装软件包，请运行： pacman -S mingw-w64-x86_64-python-pip

然后，您应该可以使用python -m pip安装jupyter和其他软件包，但是避免运行python -m pip --upgrade pip，因为这将覆盖打包的版本。

我还建议通过运行python -m venv .venv和source .venv/bin/activate使用virtualenv来使pip安装的软件包完全分开。

Answer 2

您可以使用pacman安装它：

compute

如果您需要git：

n = int(input())
a = "_"
b = "|"
for i in range(0,n,1):
    if i == 0:
        print(" " * (2*n - 1) + "_*_")
        print(" " * 2*((n - 1)) + b + " " * 3 + b)
    else:
        print(" " * ((2*n - 1) - 2*i) + a + (" " * ((i + 1) * 4 - 3) ) + a)
        print(" " * ((2*(n-1)) - 2*i)  + b + (" " * ((i + 1)*4 - 1)) + b)

在MINGW64上点对点？
