Postgress error- bundle install

问题

When I run

$bundle install

I am running the project on heroku so I had to switch to postgress. I keep getting this error for some reason.

An error occurred while installing pg (0.15.1), and Bundler cannot
continue.
Make sure that gem install pg -v '0.15.1' succeeds before bundling.

回答1:

From your Gemfile it seems that you are using sqlite3 for development and postgres for production. You don't have to install postgres locally. Just do bundle install without production group:

bundle install --without production

回答2:

Try removing the version in the gem file: gem 'pg' only...

回答3:

Try bundle install --without development test postgresql
