AWS-Heroku-Ruby on Rails-无法通过Bundler安装gem

Question

I am running bundle update in the AWS environment but I am getting an error:

An error occurred while installing pg (0.20.0), and Bundler cannot continue. Make sure that gem install pg -v '0.20.0' --source 'https://rubygems.org/' succeeds before bundling.

I am following the this tutorial . When I run git push Heroku master , it says it failed to install gems via bundler .

Im not sure why I cannot install the gems needed.

Any help or guidance would be greatly appreciated. Thank you

Answer 1

I don't know but i think you should run this step before bundling

gem install pg

Answer 2

Are you trying to deploy to AWS or Heroku?

If it's Heroku:

The pg version's that Heroku uses is: 0.21.0

So, you should put into your Gemfile:

gem 'pg', '0.21.0'

And then commit and push to Heroku

If it's AWS:

You should try just as @Kumar commented on your post...
