python - pip install google-cloud-pubsub 在 docker 容器中安装失败

Question

我正在尝试使用 pupsub 模拟器。它开始了，但是当我尝试使用我的 python 脚本时，我收到以下错误

ModuleNotFoundError: No module named 'google'

所以我尝试安装模块。

RUN pip install google-cloud-pubsub

错误

我不确定您为什么要尝试安装 python3 和 pip3，它们都存在于基础镜像中。在任何情况下，这个 Dockerfile 都会以漂亮干净的图像为您提供 python google-cloud-pubsub 库

FROM google/cloud-sdk:alpine

RUN apk add --no-cache --virtual .build-deps \
    linux-headers build-base g++ python3-dev \
    && pip3 install --no-cache-dir google-cloud-pubsub \
    && apk del .build-deps

# add your stuff here
