无法安装gem pg

Question

I just started learning Ruby on Rails with my mac and I'm stuck. I'm using PostgreSQL as my database, and of course, the gem 'pg'.

When I bundle install or I try to create a controller it gives me lots of syntax errors. However, if I delete that gem from my gemfile, I get no syntax errors.

I used to have that gem as gem 'pg' with fancy quotes and it gave me an error related only to that line. Something like

can't find gem pg

I've been searching questions related here, but none of them showed me an answer, even though I tried everything I saw. I also asked a guy who works with RoR and he told me to change the quotes' shape (from fancy to normal), which lead to the error I have shown you.

Answer 1

首先，您应该为pg gem安装本机扩展：请考虑以下主题在OS X上安装PG gem-无法构建本机扩展然后，您应该能够使用gem install pg安装该gem。
