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.

我确定我输入了用于登录网页的确切用户名和密码。任何人都可以帮助指出错误并帮助我解决吗？

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)
