python - 导入具有 Visual C++ 依赖项的包时出错 : invalid numeric argument '/Wno-cpp'

Question

我正在尝试在 Window 10 上使用 PyCharm 加载 pycocotools ( from here ) 包。

一开始我遇到了以下错误:

Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": 

因此，我安装了 Visual Studio 2019 并启用了 C++ 包。看起来它解决了错误，但现在我有另一个错误，这对我来说很神秘:

error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.21.27702\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2

这是完整的堆栈跟踪:

You are using pip version 10.0.1, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

可能是什么问题以及如何解决？

Coco 维护者不提供 Windows 中的支持，请检查 issue #9 :

We will not be providing Windows support.

但幸运的是，有一个可以在 Windows 上编译的分支:https://github.com/philferriere/cocoapi

只需运行:pip3 install "git+https://github.com/philferriere/cocoapi.git#egg=pycocotools&subdirectory=PythonAPI"
