问题描述

我正在尝试使用pupsub模拟器。它开始了，但是当我尝试使用python脚本时，出现以下错误

I am trying to use a pupsub emulator. It starts but when I try to use my python script I get the following error

ModuleNotFoundError: No module named 'google'

所以我尝试安装模块。

推荐答案

为了安装该客户端，您需要在其中安装gcc您的Docker容器。它正在尝试使用cc命令来编译库的一部分。尝试在google-cloud-pubsub软件包之前安装cython软件包。

It looks like in order to install that client, you need gcc installed in your docker container. It is trying to use the cc command to compile part of the library. Try installing the cython package prior to the google-cloud-pubsub package.

还要注意，Google Cloud Pub / Sub客户端库的0.24.0版本是三岁;现在，它的版本为1.5.0。此依赖性问题（以及许多其他问题）可能已在此期间修复，因此可能值得更新至较新版本。

It is also worth noting that version 0.24.0 of the Google Cloud Pub/Sub client library is three years old; it is now up to version 1.5.0. This dependency issue (along with many other things) may have been fixed somewhere in the meantime, so it might be worth updating to a more recent version.
