ValueError:未知MS编译器版本1900 [英] ValueError: Unknown MS Compiler version 1900
问题描述
我想使用cygwin(mingw)在Windows 10上使用Python 3.5运行一些代码。准确地说,我使用PyDSTool模块,我在这里调用dopri积分器。问题是,我遇到麻烦与 distutils
不能识别Microsoft Visual Studio 2015.有一种方法来避免这一点(不回到旧版本的Python,Windows,Visual工作室)。

解决方案Distutils和Numpy / Distutils目前不支持Visual Studio 2015,Visual C ++ 14.以下提示根据Python错误报告,我能够修补必要的文件,并使用新的安装成功构建扩展的Python 3.5从Anaconda和Mingw64与GCC 5.2.0在MSYS2在Windows 7上运行。我没有安装Visual Studio。解决方案是修补一个distutils文件和两个numpy / distutils文件(如果适用)。
您可以自行应用这些补丁以快速修复:
UPDATE
请注意,对我来说,它不被接受列入上游。 VS 2015的变化比我所欣赏的更复杂。
I am trying to run some code with Python 3.5 on Windows 10 with the use of cygwin (mingw). To be precise I am using the PyDSTool module, where I call the dopri integrator. The problem is, I am having trouble with distutils
not recognizing Microsoft Visual Studio 2015. Is there a way to avoid this (without going back to older versions of Python, Windows, Visual Studio). The full Error can be seen bellow.

Distutils and Numpy/Distutils currently do not have support for Visual Studio 2015, Visual C++ 14. Following tips drawn from the Python bug report, I was able to patch the necessary files and successfully build extension using a new install of Python 3.5 from Anaconda and Mingw64 with GCC 5.2.0 running within MSYS2 on Windows 7. I do not have Visual Studio installed. The solution was to patch one distutils file and two numpy/distutils files (if this applies). These patches have been submitted for inclusion in future revisions.
You can apply the patches yourself for a quick fix:
UPDATE
Please note that while the patches above worked for me it was not accepted for inclusion in upstream. The changes that came with VS 2015 are more complex than I appreciated.
