Heroku 无法安装 av (pyav)

Heroku fails to install av (pyav)

我一直在尝试设置我的 Python 网络应用程序,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 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,但同样失败,gcc 在这里失败:

    __pyx_v_ptr = av_codec_iterate((&__pyx_v_opaque));
                ^~~~~~~~~~~~~~~~

有人遇到过这种情况吗?或者有在 Heroku 中使用 av/pyav 的经验吗?请告诉我任何我错过的事情。谢谢

事实证明,Heroku 使用 requirements.txtPipfile 效果更好。更改安装文件后,部署过程顺利。
