python-3.x - 有没有办法为 Windows 安装 cython-bbox？

问题描述

我已经安装了 Visual Studio 并试图运行一个依赖于cython_bbox包的 Python3 程序。我尝试pip install cython-bbox在 Windows Anaconda3 环境中安装它，但出现以下错误：

  Building wheel for cython-bbox (setup.py) ... error
  ERROR: Command errored out with exit status 1:

这个错误可以解决吗？什么是/Wno-cpp，我需要编辑一些源文件吗？

解决方案

我刚刚解决了这个问题。我从 PyPI 下载了 tar.gz 文件，将其解压缩并编辑了源文件。为了方便 Windows 支持，cd 进入包目录，然后将 setup.py 文件中的第 31 行从extra_compile_args=['-Wno-cpp'],更改为extra_compile_args = {'gcc': ['/Qstd=c99']}.

然后，您可以使用pip install -e /path/cython_bbox-0.1.3.tar/dist/cython_bbox-0.1.3/cython_bbox-0.1.3. 如果成功，您应该看到以下内容：

Installing collected packages: cython-bbox
  Running setup.py develop for cython-bbox
Successfully installed cython-bbox

希望这对某人有帮助！
