我试图让我的 django 应用程序使用 PostgreSQL，但是，到目前为止还没有运气。我将应用程序设置为使用 PostgreSQL 数据库并使用 docker-compose.yml 链接两个容器，但是我收到了模块 psycopg2 丢失的错误。我按如下方式安装了所有依赖项:apk --update add python3-dev, postgresql-client, postgresql-dev, musl-dev，当我尝试使用 pip pip3 install psycopg2 安装 psycopg2 时，出现以下错误:

我是否缺少依赖项或者我是否安装了 psycopg2 错误？
最佳答案
将此添加到 django 应用程序的 Dockerfile 中
RUN apk add build-base
它就像 build-essentials，包括用于编译 C/C++ 的基本构建工具

关于python - 在 alpine docker 容器中安装 psycopg2，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/42424108/
