python - Python fancyimpute安装在Mac上，但未安装在Windows上

Question

我是一个试图安装Python的'fancyimpute'软件包的小组的成员。我们三个有不同的Windows计算机。我们其中之一拥有Mac。
fancyimpute的page说:'Operating System::OS Independent'。
我的队友在Mac上安装它没有任何问题:pip install fancyimpute可以正常工作。

当我们Windows用户尝试执行相同操作时，出现此错误:
“错误:需要Microsoft Visual C++ 14.0。使用“Microsoft Visual C++生成工具”获取它:http://landinghub.visualstudio.com/visual-cpp-build-tools“

我们已经安装了“Visual C++ 2015构建工具”，但仍然无法安装fancyimpute。 我们遇到的错误如下:

'NAN'
  ecos/src/ecos.c(1093): warning C4013: '_set_output_format' undefined; assuming extern returning int

  ecos/src/ecos.c(1093): error C2065: '_TWO_DIGIT_EXPONENT': undeclared identifier

  error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\cl.exe' failed with exit status 2

  Failed building wheel for ecos

对于Windows机器所有者来说，这是否是一个无望的案例？还是有解决方案？

Answer 1

我刚刚在Windows 10计算机上安装了fancyimpute，并且成功。如果您是从pycharm控制台执行操作，可以请尝试从命令提示符处运行pip命令。
