我有一个python Django项目。当我manage.py runserver通过虚拟环境运行其manage.py脚本时，出现以下导入错误。注意：我正在使用Fedora 26
ImportError:
/home/xxxxx/Projects/Dev/yyyy/ENV/new_env/lib/python2.7/site-packages/psycopg2/.libs/libresolv-2-c4c53def.5.so:
symbol __res_maybe_init, version GLIBC_PRIVATE not defined in file
libc.so.6 with link time reference
可能是什么原因？
我正在运行一个安装脚本来安装许多不同的 python 包。被困住的是psycopg2。该脚本尝试安装 version 2.6.1。但我遇到了错误：
Error: could not determine PostgreSQL version from '10.10'
我认为这与版本不兼容psycopg2有关。这是一个无效的结论吗？postgresql10.10
假设我对版本不兼容的结论是正确的，我将 的安装版本更改psycopg2为2.7. 通过这样做，上面的错误就消失了。
但是，当我运行时：
python manage.py runserver 0.0.0.0:888
我收到错误：
