ImportError:没有名为postgresql的模块,已安装psycopg2
对于安装OpenGnSys,我们需要运行脚本,然后调用python脚本。这python脚本提供了以下错误:ImportError:没有名为postgresql的模块,已安装psycopg2
[[email protected] opengnsys2-web]# ./db.py postgresql://opengnsys:[email protected]/opengnsys
Traceback (most recent call last):

ImportError: No module named postgresql
净搜索后,我发现,模块psycopg2
应安装postgesql
。但就我而言,它已经在那里。可能是什么问题?
回答:
Are we talking about a misconfiguration of the url
postgresql://opengnsys:[email protected]/opengnsys
VS
postgresql+psycopg2://scott:[email protected]/mydatabase
