Google 不是我的朋友，我找不到这是什么原因造成的。这发生在“apt upgrade”之后，所以我拥有所有最新的包（python，...）

【问题讨论】：

【参考方案1】：

这是一个known issue，随着 274.0.0 Cloud SDK 版本的发布而开始发生。即使抛出错误，安装也会顺利进行（使用gcloud info 检查 Cloud SDK 版本）。工程部门意识到了这一点，他们正在研究它。

当前的解决方法是安装以前版本的 Cloud SDK，例如带有sudo apt-get install google-cloud-sdk=272.0.0-0 的 272.0.0。

更新：

Cloud SDK version 275.0.0 的发布解决了该问题 - 使用基于 Linux 的软件包工具安装 Cloud SDK 不应再引发上述错误。如果您仍然遇到问题，请open an Issue Tracker thread under the Cloud SDK component 解释您遇到的问题。

【讨论】：

mmh.. 不完全：kgoderis@supermicro:/usr/share$ gcloud info -bash: /home/kgoderis/google-cloud-sdk/bin/gcloud: 没有这样的文件或目录跨度> @KarelGoderis 尝试使用 sudo apt-get install google-cloud-sdk=273.0.0-0 安装以前版本的 Cloud SDK，看看问题是否仍然存在。 旧版本对我来说失败了，下面是Compiling lib/googlecloudsdk/api_lib/dns/active_peering_zones.py ... SyntaxError: future feature google_type_annotations is not defined (active_peering_zones.py, line 19) @AdamWilliams 这似乎是一个单独但可能相关的问题，我也复制了它。进行了更多测试，最终我设法使用sudo apt-get install google-cloud-sdk=272.0.0-0 安装了 Cloud SDK 版本 272.0.0。试试吧。 @Maxim - 谢谢 - 安装 272 适用于 Ubuntu 18.04 服务器安装。 274 失败，如上面的注释。【参考方案2】：

Python3

我遇到了同样的 YAMLObjectMetaclass 语法错误，并通过设置以下环境变量将 gcloud、gsutil 和 bq 配置为使用 Python 3 解决了这个问题：

ENV CLOUDSDK_PYTHON=python3
ENV CLOUDSDK_GSUTIL_PYTHON=python3
ENV CLOUDSDK_BQ_PYTHON=python3

见：gcloud topic startup

设置上面的3个环境变量后，我就可以成功安装gcloud sdk 27​​4.0.1-0了。

Dockerfile 代码块：

FROM ubuntu:1810
#...removed section for brevity
# install google cloud platform sdk with python3
# see: https://cloud.google.com/sdk/gcloud/reference/topic/startup
ENV CLOUDSDK_PYTHON=python3
# gsutil now supports Python 3.5 and up in addition to Python 2.7.x.
# To use a different interpreter for gsutil than for the other Python tools,
# you can set the desired interpreter by setting
# the CLOUDSDK_GSUTIL_PYTHON environment variable.
ENV CLOUDSDK_GSUTIL_PYTHON=python3
# bq now supports Python 3.5 and up in addition to Python 2.7.x.
# To use a different interpreter for bq than for the other Python tools,
# you can set the desired interpreter by setting the
# CLOUDSDK_BQ_PYTHON environment variable.
ENV CLOUDSDK_BQ_PYTHON=python3

【讨论】：

至少在 Ubuntu 19.10 (eoan) 上，SDK 在安装期间 继续使用 python2.7 ("Setting up google-cloud-sdk (274.0.1-0) ...") 尽管设置了这些环境变量。
