Access WRDS data through Google Colab: OperationalError

Question

I've tried to access data from WRDS through Google Colab by using wrds.Connection() function. But I got the OperationalError. I accessed data from WRDS through Google Colab many times before but this is the first time I face this problem. I changed password, computer, browser many times but it still didn't work.

Anyone please take a look and give me a comment so that I can get through this issue. Many thanks!

Enter your WRDS username [root]:.........
Enter your password:........
WRDS recommends setting up a .pgpass file.
You can find more info here:

There was an error with your password.

Answer 1

I was able to get past the issue by updating wrds library using !pip install --upgrade wrds.

Answer 2

I had no trouble. I installed the wrds library using !pip install wrds, then I ran conn = wrds.Connection(), entered my WRDS ID and password, and it all worked. One idea might be to reinstall the library and try again.
