I am new to Ruby on Rails and I'm trying to create a website using the same. I have added a few gems to my gem file and trying to bundle them, but encounter this error.
An error occurred while installing eventmachine (1.2.7), and Bundler cannot continue.
Make sure that gem install eventmachine -v '1.2.7' --source 'https://rubygems.org/' succeeds before bundling.
I have tried doing gem install eventmachine -v '1.2.7' but get this error:

You seem to be missing the c++ development source necessary for ruby to install openssl.
Install libssl-dev and try the gem installation again. You may be missing other development libraries as well.

I tried to Launch rails server on vagrant but I can't.
The error message is here.
Could not find gem 'sqlite3 (~> 1.4.0)' in any of the gem sources listed in your Gemfile.
Run `bundle install` to install missing gems.
I did bundle install but...

What should I do next?
I am using Windows, and I just installed Ruby on Rails, ruby is version 2.6.3p62 (2019-04-16 revision 67580) [x64-mingw32], rails is version 6.0.0.
When running rails new blog (following this tutorial) bundle install runs.
I have tried reinstalling Ruby, changing its version, and even removing bootsnap and running something else, but even when trying to install the puma gem I get the same error.

Actually, Bootsnap won't work on Windows anyway, so I'd recommend just removing it from Gemfile. If you want to leave it for production environment, perhaps you should include it conditionally with something like:
gem 'bootsnap' unless (RbConfig::CONFIG['host_os'] =~ /mswin|mingw|cygwin/)
When I tried to install the
gem install escape_utils -v '0.3.2'
it gives me following errors which I don't know how to fix
I am using

This is issue with escape_utils itself. You should edit Gemfile.lock file and change escape_utils (0.3.2) to escape_utils (1.1.0).
I'm learning R o R. Then, I want to make a website by using postgresql.
But, this error makes me crazy.
Please, help me !

An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.
I tried all ways I could.
For example, I tried to change pass of pg.
But, I couldn't.
Then, I tried
$ brew update
$ brew uninstall postgresql
$ brew install postgresql
$ gem install pg
$ bundle install
But, it didn't work.
How can I do for this error !?
You might require libpq-dev, which is the library that always gets me when trying to install the pg gem on a new machine.
I struck the same problem when running the pg gem 0.17 with Ruby 2.2.1
I just did a bundle update pg and it upgraded to 0.18 and it no longer had this compile issue
I'm trying to upgrade my rails 3.2.3 app. I've updated the gemfile to gem 'rails', '3.2.11' and ran bundle update rails but got the following error:

So I tried the solution that I found everywhere, to create a symlink using the command:
sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
but that just returns the error:
ln: /usr/bin/gcc-4.2: File exists
I don't know a lot about using the terminal to navigate around OSX, so I'm kind of struggling here. Any ideas?
/usr/bin/gcc-4.2 could already be a symlink, but a broken one that points to a nonexistent file.
