Heroku无法安装av(pyav)

Question

我一直在尝试设置我的Python web应用程序，该应用程序使用opencv、tensorflow和av模块，但一直失败。我已经尝试使用Aptfile来安装几个Ubuntu库(libsm6, libxrender1等(，但安装仍然失败。

安装失败后，heroku服务器决定从源代码构建av模块，该模块也失败了，gcc在这里失败了：

src/av/codec/codec.c:4003:19: warning: implicit declaration of function ‘av_codec_iterate’; did you mean ‘av_codec_next’? [-Wimplicit-function-declaration]
__pyx_v_ptr = av_codec_iterate((&__pyx_v_opaque));
^~~~~~~~~~~~~~~~

error: command 'gcc' failed with exit status 1

有人经历过这种情况吗？或者有没有在Heroku使用av/pyav的经验？请告诉我我错过了什么。谢谢

证明Heroku使用requirements.txt比使用Pipfile效果更好。更改安装文件后，部署过程顺利。
