I'm trying to run bundle install using ubuntu 20.04, rvm with ruby 2.7.2, and I can't get the eventmachine gem to install.
After googling for hours I couldn't find a solution that works for me. I've tried deleting the lockfile and running bundle, ruby-dev is already installed with the latest version, I've tried running bundle with ruby 2.6.6, updating bundle, updating Jekyll from 4.0.0 to 4.2.0, and no matter what I try I'm still getting these error messages I don't understand, so any help would be VERY appreciated!
Gemfile
source 'https://rubygems.org'
gem 'jekyll', '4.0.0'
group :jekyll_plugins do
gem 'jekyll-feed', '0.12.1'
gem 'jekyll-paginate', '1.1.0'
gem 'jekyll-seo-tag', '2.6.1'
gem 'jekyll-sitemap', '1.3.1'
end

I tried again, this time using ruby 2.7.1 instead of 2.7.2 and it worked.
I guess some update in ruby broke it, so for anyone stuck on this try using 2.7.1 or not the latest version of ruby.
I am trying to push my app to Heroku and I configured my gemfile as such:
group :production do
gem 'pg', '0.18.4'
gem 'rails_12factor', '0.0.2'
gem 'puma'
end
And I am getting this error in my console when running bundle install:
An error occurred while installing pg (0.18.4), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.4'` succeeds before bundling.
Then when I run gem install pg -v '0.18.4', I get the following:
ERROR: While executing gem ... (Gem::FilePermissionError)

When I run sudo gem install pg -v '0.18.4'

I reinstalled RVM and rails and now when I run gem install pg -v '0.18.4', it runs successfully:

You need to have PostgreSQL installed to install pg gem. Also PATHs will need to be configured.
You can use http://postgresapp.com/ to easily install PostgreSQL on Mac. And use this to configure PATH: http://postgresapp.com/documentation/cli-tools.html
Try this it worked for me it must Have all psql dependency so it will work

Any help please?

Ubuntu 12.10 adopts Debian's hardening wrapper, which includes a set of default flags for GCC that cause this compilation error. We've worked around this in Nokogiri 1.5.4 and higher, so you'll need to either upgrade or find your own workaround.
See here for information on Debian hardening.
See here for details on the solution used by Team Nokogiri.
