使用yt-dlp DownloadError的Heroku FFMPEG后处理错误
使用yt-dlp DownloadError的Heroku FFMPEG后处理错误
提问于 2022-02-14 00:47:40
我正在建立一个不和谐的音乐机器人，使用FFMPEG下载和播放音乐。由于某种原因，yt似乎无法找到ffmpeg文件，尽管我给出了它的直接路径。当我在我的cpu上运行它时，它工作得非常好，但是它在heroku中不工作。
以下是heroku中的错误：

你不能这么做：
'ffmpeg_location': './FFMPEG_CONFIG/ffmpeg.exe',ffmpeg.exe是一个Windows二进制文件。它不能在Heroku上使用(而且不应该是您的存储库的一部分)。
大多数想在Heroku上使用ffmpeg的用户使用建筑群 (也请参阅多个构建包)，例如：
heroku buildpacks:set heroku/python
heroku buildpacks:add --index 1 https://github.com/FFmpeg/FFmpeg.git然后删除硬编码的ffmpeg_location，提交和重新部署。你的应用程序应该能找到ffmpeg。
对于本地开发，您有以下几种选择：
- 更新您的
PATH以确保可以找到ffmpeg.exe - 更新代码以设置
ffmpeg_location，最好是使用环境变量
