Heroku无法安装AVpyav

如何解决Heroku无法安装AVpyav

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。我尝试使用Aptfile安装多个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，该模块也会失败，并且gcc在此处失败：

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));
                ^~~~~~~~~~~~~~~~
                av_codec_next

    __pyx_v_ptr = av_codec_iterate((&__pyx_v_opaque));
                ^

                                    ^~~~~~~~~~~~~~~~~~~~~

                                    ^~~~~~~~~~~~~~~~~~~
                                    AV_CODEC_CAP_DR1

有人经历过吗？或在Heroku中使用AV / pyav有任何经验吗？请告诉我我错过的任何事情。谢谢。

解决方法

结果证明，使用requirements.txt比使用Pipfile更好地使用Heroku。更改安装文件后，部署过程正常。
