pg gem的Rails和bundle安装错误？

Question

I am trying to install Ruby on Rails on my MacBook Pro running Yosemite 10.10 for my school program. I have installed everything successfully but now when I run rails s I get this error. I have tried to continue with bundle install to solve the issue but as you can see it does not work. What is going on here? I proceeded to try with sudo but it failed as well.

▶ rails s
Could not find pg-0.18.1 in any of the sources
Run `bundle install` to install missing gems.

Answer 1

Have you updated your OSX recently? Maybe you need to update your xcode/xcode tools and then reinstall postgres.

Have you installed postgres by homebrew? If yes, try to reinstall running

brew uninstall postgresql

and then

brew install postgresql

Then, try again to run "bundle install".

Answer 2

Add 'pg' gem into your gemfile instead installing it manually in your terminal and run 'bundle install'. Add this in your gemfile: `gem 'pg'

Answer 3

A slightly less heavy handed version of penner's answer, I had the same problem and after some digging discovered that the pg-0.18.1 directory in lib/ruby/gems/2.2.0/gems/ was owned by root (probably due to a mistaken use of sudo as he notes). I rm -rf ed that directory (and an extensions one that failed the install after the gems one was cleaned up) and after that the install worked.

Short answer: ls -la your way down through that long path the error gives you, and when you find any directories owned by root, get rid of them.

Answer 4

Might be heavy handed

chown -R jonathanmusso:staff /Users/jonathanmusso/.rvm

If you've used sudo with rvm you might have broken the install. Try updating rvm.
