求大佬解决下载psycopg2的问题
问题描述：
服务器上装着python2和python3.
python2装了psycopg2，pip show可以看到，但是import失败，pip uninstall也不行显示
Cannot uninstall 'psycopg2'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
python3没有psycopg2，pip3 install显示
command 'gcc' failed with exit status 1
按照网上说的安装python3-devel也没卵用
答
这个包安装需要很多依赖，不但需要python-dev还需要gcc编译，如果感觉麻烦可尝试安装二进制版本
pip install psycopg2-binary
