python - Google Cloud Composer，无法安装 python-snappy

Question

我正在尝试通过 Google Cloud Platform 控制台在 Google Cloud Composer 中安装 python-snappy。我使用的是python3环境。

我曾尝试安装不同的 python-snappy 版本(0.5.3、0.5.2、0.5.1、0.5、0.4)，但是，它总是会引发此错误:

Http error status code: 400 Http error message: BAD REQUEST Additional errors: {"ResourceType":"w071b50175ee0733c-tp/asia-northeast1-kumparan-co-e2ca75b3-gae-typer:appengine.apps.services.versions.create","ResourceErrorCode":"400","ResourceErrorMessage":"Docker image gcr.io/w071b50175ee0733c-tp/c949bad3-ca30-4717-a975-8e36bae3929a was either not found, or is not in Docker V2 format. Please visit https://cloud.google.com/container-registry/docs/ui "}

我也尝试过重新运行，如下所述:https://groups.google.com/forum/#!topic/cloud-composer-discuss/jpxAGCPFkZo .

但是，就我而言，它并没有解决这个问题。

有人知道如何解决吗？

如果您导航至https://console.cloud.google.com/cloud-build/builds/ ，您应该会看到失败的构建，并显示以下日志:

这是因为 python-snappy 包只是与底层 C 库的 Python 绑定(bind)，而不是 C 库本身。

参见"Error installing python-snappy: snappy-c.h: No such file or directory"了解更多详情。
