安装python aiortc模块在msys2 mingw-64



我正在尝试在msys2环境中安装aiortc模块。

(尝试使用几种方法(pip, python -m pip, git clone，…)尝试由于30000个字符限制而删除)

问题在于lvpxmt库无法在msys平台上使用pacman命令。

编辑:我找到了一个解决方案，但没有稳定的，所以我需要你的帮助，一个更好的解决方案:

  1. 我修改https://github.com/aiortc/aiortc/blob/main/src/_cffi_src/build_vpx.py
'''
if sys.platform == "win32":
libraries = ["vpxmt"]
else:
libraries = ["vpx"]
'''
libraries = ["vpx"]

  1. 我从msys终端运行pacman -S mingw-w64-x86_64-libvpx

  2. 然后git clone, python setup.py build和python setup.py install.

执行以上步骤后，可以成功导入aiortc模块。

问题是当我运行一个应用程序，我做，当一个连接请求，然后这里是错误。

我不相信这是应用程序错误，因为完全相同的应用程序在不同的环境(不同于msys)中运行没有错误。

那么，我如何解决这个错误?如果需要，我可以提供我运行的aiortc应用程序代码。

看来谷歌今天(2021年8月30日)发布的google-crc32c 1.1.3更新有问题。几天前，我有一个构建工作，开始失败，在github操作上出现了完全相同的错误。我通过返回到1.1.2解决了这个问题，它可以正常工作。

我建议你试试

pip install google-crc32c==1.1.2 aiortc

这应该会给你一个crc32的工作版本。
