如何在 Google Cloud Platform 灵活环境中将 PySoundfile 获取到 运行？

Question

我有一个简单的应用程序，我想将其部署到 GAE 标准或灵活的环境中，它需要生成简单的音频文件。

我的代码 运行 在本地（在开发服务器上）使用 PySoundfile 很好，但是我 运行 在应用程序时 libsndfile 与底层 libsndfile 发生错误已部署。

Traceback (most recent call last):

    raise OSError(msg)
OSError: ctypes.util.find_library() did not manage to locate a library called 'sndfile'

我也试过wave失败了。

在灵活的环境中，您可以尝试构建和使用自定义运行时，您可以在其中添加非 python 依赖项，例如 OS 库（在您的情况下为 libsndfile 和你可能需要的任何其他东西）。

基本上与中的答案相同。
