I am trying to run a bundle install on a rails app. The installation fails on the step: Installing pg 1.1.3 with native extensions
Here is the complete error log:

Gem files will remain installed in /Users/velinapetrova/.rvm/gems/ruby-2.5.1/gems/pg-1.1.3 for inspection.

An error occurred while installing pg (1.1.3), and Bundler cannot continue.
Make sure that `gem install pg -v '1.1.3' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
pg
Running the gem install pg -v '1.1.3' --source 'https://rubygems.org/' produces the same error message.
I have reinstalled postgres.
I have set up my bundle.config to point to the correct pg_config file.
回答1:
sudo apt-get install postgresql-client libpq5 libpq-dev
回答2:
The following worked for me (took from this post)
brew reinstall libffi
export LDFLAGS="-L/usr/local/opt/libffi/lib"
export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
gem install jekyll
and everything worked smoothly.
Hope this works also for you (I spent far way too much time with this issue with iff)
