“easy_install -U cython”未能抱怨 vcvarsall.bat 和 -mno-cygwin
在 Windows 下,带有 C 依赖项的 easy_install
似乎不太容易。
尝试 1 - vcvarsall.bat
错误
我正在 Windows7 下使用 MinGw
安装 cython
;我修改了 Windows7 的 PATH
以包含 C:\MinGw\bin
。此时,我尝试 easy_install -U cython
,并得到...

尝试 2 - 修复 vcvarsall.bat
错误
接下来,按照我发现的博客的建议,我还尝试将其放入 C:\Python27\Lib\distutils\distutils.cfg
中以修复 vcvarsall.bat
错误。

这只会有一点帮助...

警告 - 没有 cygwin 或预编译的二进制文件
我意识到我可能能够在 cygwin 下工作;但是,我不希望 cygwin 依赖于此库;我需要本机 Windows7 输出。
如果可能的话,我想避免 预编译的 Cython 二进制文件 因为作为作者说,它们“不受支持,仅用于测试目的”。
问题
如何使用 MinGw
在 Windows7 下通过 easy_install
安装 cython
?
Under Windows, it seems that easy_install
with a C dependency isn't very easy.
Attempt 1 - vcvarsall.bat
errors
I am installing cython
under Windows7, with MinGw
; I modified Windows7's PATH
to include C:\MinGw\bin
. At this point, I tried to easy_install -U cython
, and got...

Attempt 2 - Fix vcvarsall.bat
errors
Next, following the advice of a blog I found, I also tried putting this in C:\Python27\Lib\distutils\distutils.cfg
to fix the vcvarsall.bat
error.
[build]
compiler=mingw32
This only helps marginally...

Caveat - No cygwin or precompiled binaries
I realize that I might be able to get this working under cygwin
; however, I don't want cygwin
dependencies on this library; I need native Windows7 output.
If possible, I would like to avoid precompiled Cython binaries because as the author says, they are "unsupported and for testing purposes only".
Question
How can I get cython
to install via easy_install
under Windows7 with MinGw
?

经过更多谷歌搜索后,我发现建议从
C:\Python27\Lib\distutils\cygwinccompiler.py
中删除-mno-cygwin
,因为 distutils 错误。从
C:\Python27\Lib\distutils\cygwinccompiler.py
中删除-mno-cygwin
即可编译cython
。After more some googling, I found guidance that recommended removing
-mno-cygwin
fromC:\Python27\Lib\distutils\cygwinccompiler.py
because of a distutils bug.Removing
-mno-cygwin
fromC:\Python27\Lib\distutils\cygwinccompiler.py
gotcython
to compile.
