问题
Trying to test a website built on Rails and keep getting an error that refuses to allow me to set up my server.
After getting an error, I used 'gem install bootsnap -v '1.4.2' --source 'https://rubygems.org/' with the source as Rubygems. Same error:

My gemfile includes this:
# Reduces boot times through caching; required in config/boot.rb
gem 'bootsnap', '>= 1.4.2', require: true
I do see bootsnap located: C:\RailsInstaller\Ruby2.3.3\lib\ruby\gems\2.3.0\gems
Would anyone know how to get rid of this? It is not located on my gem list either.

I had the same problem and I'm also using railsinstaller on a windows computer.
To solve it, I updated my Gemfile like this :
#gem 'bootsnap', '>= 1.1.0', require: false
gem 'bootsnap', '= 1.4.1', require: false
Then run the command : bundle install in your project directory.

I also encountered the same problem. I'm using ruby 2.3.0, rails 5.2.3. To solve it, I updated my Gemfile.
# it don't work....
# gem 'bootsnap', '>= 1.1.0', require: false
# gem 'bootsnap', '>= 1.4.2', require: false
gem 'bootsnap', require: false
Then bundle install and it works!
