如何修复连接到 'wrds' 数据库的错误？

Question

我正在尝试使用模块 'wrds' 中的函数 'WRDS.Connection()' 连接到 'wrds' 数据库，我输入了我的用户名和密码，但它建议我设置一个 . 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.

我确定我输入的用户名和密码与我在网页上登录时使用的用户名和密码完全一致。谁能帮我指出错误并帮我解决？

确保您拥有最新版本的 wrds，如果这不能解决此问题：

尝试通过将您的用户作为参数传递来进行连接：

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