在亚马逊上安装 psycopg2 时出错 Linux

Error Installing psycopg2 on Amazon Linux

使用此命令在 Amazon Linux 上安装 psycopg2 时:sudo pip-3.4 install psycopg2 我得到以下输出:

我已经安装了 gccpostgresql-develpostgresql-libspython34-devel。我是否缺少包裹或设置?

编辑:这是在 EMR 节点上。

我和EMR有同样的问题,我在下面试过

sudo yum -y install gcc python-setuptools python-devel postgresql-devel
sudo /usr/bin/pip install --upgrade pip 
sudo /usr/local/bin/pip install psycopg2

它在我 运行 在 EMR 上工作时有效,但在 EMR 从 Pipeline 启动时不起作用。

如果您正在亚马逊 linux 中为 python3 寻找 psycopg2,这对我有用:

sudo yum install -y gcc postgresql-devel
sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python36
sudo pip-3.6 install -U psycopg2

如果您尝试为 python3 安装 psycopg2,您还必须安装 python3-devel。

找到正确的包 yum search python3 | grep devel

在我的例子中是 python36-devel 所以我做了 sudo yum install python36-devel

然后我可以在机器上为我的 python3 虚拟环境安装 psycopg2
