如何修复连接到“ wrds”数据库的错误？

时间：2019-05-10 13:20:37

标签： python wrds wrds-compusat

我正在尝试使用模块'wrds'中的函数'WRDS.Connection（）'连接到'wrds'数据库，我输入了用户名和密码，但是建议我设置.pgfile并引发错误

import wrds
conn = wrds.Connection()
Enter your WRDS username [veggiesong]:huhuhuhu
Enter your password:
WRDS recommends setting up a .pgpass file.
You can find more info here:
https://www.postgresql.org/docs/9.5/static/libpq-pgpass.html.
There was an error with your password.

请确保您拥有最新版本的wrds，如果这样做不能解决此问题：

尝试通过传入用户作为参数进行连接：

import psycopg2
conn = psycopg2.connect(dbname='wrds', 
                        user='my_username', 
                        host='wrds-pgdata.wharton.upenn.edu', 
                        port=9737)
