python - Pyo Python DSP 模块不会部署到 Heroku

问题描述

所以我试图在 Heroku 上放置一个 django 项目的演示，该项目在本地运行良好并在我卸载 Pyo 包时加载，但是当我重新安装它时它会引发 OSerror（OSError at / Exception Value: /app/.pyo /3.6_64/libs/libasound-fb332ab3.so.2.0.0：无法打开共享对象——完整回溯见下文）。我添加了一个 buildpack 来安装 libasound 和推荐的软件包，但我仍然收到错误消息。我错过了什么？我看到了 Linux 轮子修复符号链接（https://github.com/belangeo/pyo/blob/master/pyo/_linux_wheel_fix_symlinks.py）。问题在这里吗？非常感谢任何帮助。

错误：

解决方案

我只想把这个留给以后遇到这个问题的任何人。由于创建的符号链接轮试图从 ibasound-fb332ab3.so.2.0.0 和 libjack-07a61c7b.so.0.1.0 的 ./app 文件夹中伸出，Pyo 将无法在爱好开发 Heroku DYNO 上工作，但 Heroku应用程序无法访问该目录，因为它是存储所有内容的地方。

您可以安装在其他云环境中，例如 Digital Ocean 和 Amazon EC2，您可以在服务器上安装 Ubuntu 并拥有完全访问权限。我选择了 Digital Ocean 有一段时间，但最后只是教客户如何在本地运行 Web 应用程序并编写代码将生成的文件推送到 Amazon s3。
