我一直在尝试设置我的 Python Web 应用程序,它使用 opencv、tensorflow 和 av 模块,但一直失败。我曾尝试使用Aptfile安装几个 Ubuntu 库(libsm6, libxrender1等),但安装仍然失败。

安装失败后,heroku 服务器解析为从源代码构建 av 模块,这也失败了,gcc 在这里失败:

    __pyx_v_ptr = av_codec_iterate((&__pyx_v_opaque));

                                    AV_CODEC_CAP_DR1

有没有人经历过这个?或者有在 Heroku 中使用 av/pyav 的经验吗?请告诉我我错过的任何事情。谢谢。

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