Answer 1

Make sure you have installed postgres for Windows. There are official installers here . Then try again.

Then, if you still experience problems, try manually installing the pg gem first by:

bundle install pg

If you still have trouble you can also look at running rails, postgres, and all your other dependencies like the rest of your gems, redis, etc., on docker. Running ruby on Windows is a notoriously horrible experience. There's many things which aren't as easy as they are on Linux. Docker can solve a lot of those problems for you if you're still having trouble.

Answer 2

gem sources --add https://rubygems.org/ 

解决了此问题。
