I'm trying to set up Rails 6 with a PostgreSQL database in AWS Cloud9. Here are the steps I've taken.
I set up a new environment in cloud9 with a Ubuntu Server 18.04 LTS platform.
Then I install the latest version of rails with gem install rails
Then I check the rails version with rails -v which returns Rails 6.1.4.1
Then I create a new rails app with rails new my_app -d postgresql However, this returns the error in the build log at the end of this post.
Here are some of my trouble shooting attempts.
I tried following this suggestion sudo apt-get install libpq-dev followed by gem install pg which resulted in an error telling me to install yarn which I did via the learn enough to be dangerous tutorial source <(curl -sL https://cdn.learnenough.com/yarn_install). Then I did rails new my_app -d postgresql again resulting in a few warnings about webpacker and an error about http-proxy-middleware@2.0.1: The engine "node" is incompatible with this module but it seemed to work so I navigate to the new app and do rails db:migrate but this results in the following error message rails aborted! ActiveRecord::ConnectionNotEstablished: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?.

run bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.
