问题描述
我正在尝试将 Flask 应用程序部署到 heroku。尝试安装pocketsphinx时似乎失败了。
该项目在我的本地机器上运行良好，但无法部署。
我该如何解决？

我认为问题在于安装pocketsphinx。
我在本地机器上运行 heroku local web 并且它运行，但我无法将它部署到 heroku。

解决方法
根据错误日志，看来你需要在heroku机器上安装一个linux依赖项。
从 PyAudio docs 开始，在 ubuntu 上你需要安装两个包：python-pyaudio 和 python3-pyaudio。
很简单，在requirements.txt旁边添加一个名为“Aptfile”的新文件，并将linux包名称添加到文件中。
因此，在您的情况下，该文件将仅具有：
python-pyaudio
python3-pyaudio
在里面。
然后 heroku 将在尝试安装您的应用之前安装这些包。
您可能需要在 heroku 中添加 buildpack。
