Python fancyimpute 安装在 Mac 上，但不在 Windows 上

Question

我是一个尝试安装 Python 的“fancyimpute”包的小团队的一员。我们三个人有不同的 Windows 机器。我们中的一个有 Mac。 fancyimpute 的 page 说：“操作系统 :: OS Independent”。 我的队友在他的 Mac 上安装它没有问题：pip install fancyimpute 可以正常工作。

当我们 Windows 用户尝试执行相同操作时，我们会收到以下错误： “错误：需要 Microsoft Visual C++ 14.0。使用“Microsoft Visual C++ 构建工具”获取它：http://landinghub.visualstudio.com/visual-cpp-build-tools”

我们已经安装了“Visual C++ 2015 Build Tools”，我们仍然无法安装fancyimpute。 我们得到的错误如下：

'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，这可能是一个绝望的案例吗？或者有什么解决办法？

Answer 1

我在这里找到了解决方案：Fancyimpute pip install error

通过手动下载相应的.whl文件（Python版本和Windows架构）解决了问题：Windows binaries

导航到下载的文件（在终端中）并运行 pip install filename.whl。

Answer 2

我刚刚在 windows 10 机器上安装了 fancyimpute，它是成功的。如果您是从 pycharm 控制台执行的，请尝试从命令提示符运行 pip 命令。
