使用此命令在Amazon Linux上安装psycopg2时：sudo pip-3.4 install psycopg2我收到此输出：

我已经安装了gcc，postgresql-devel，postgresql-libs和python34-devel。我错过了包装或设置吗？

编辑：这是在EMR节点上。

Answer 1

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

当我在EMR上运行它时它起作用，但当EMR从Pipeline中旋转时它不起作用。

Answer 2

如果您要为python3安装psycopg2，则还必须安装python3-devel。

找到正确的包装 yum search python3 | grep devel

在我的情况下是python36-devel，所以我做了 sudo yum install python36-devel

然后我可以在计算机上为我的python3虚拟环境安装psycopg2

Answer 3

如果您要在Amazon 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

在Amazon Linux上安装psycopg2时出错
