I am trying to make the server start its my first time using rails. So I am using
ruby bin\rails server It gave me:
Could not find gem 'turbolinks (~> 5) x86-mingw32' in any of the gem sources listed in your Gemfile. Run `bundle install` to install missing gems. When running bundle install It gave me:
An error occurred while installing bootsnap (1.4.4), and Bundler cannot continue. Make sure that `gem install bootsnap -v '1.4.4' --source ' succeeds before bundling. When I try the command it gives me:
Error installing bootsnap: ERROR: Failed to build gem native extension. This is a snippet of the error log:

There is problem with ruby version and bootsnap gem version. so upgrade your ruby version '2.3.7' or '2.4.5' as per rails 5.2.3
Which Ruby on Rails is compatible with which Ruby version?
I had exact similar problem...took me hours I couldn't figure it out. I manually changed the version to gem 'bootsnap', '>= 1.4.4', require: false, but it didn't work.
So I solved by commenting out. This is because I figured out my application would still work without bootsnap, since it is useful for speeding up boot time by caching expensive operations.
To do so, go to Gemfile and comment out bootsnap like this:
#gem 'bootsnap', '>= 1.4.4', require: false
Then go to boot.rb file in config and comment out like below:
#require 'bootsnap/setup' # Speed up boot time by caching expensive operations.
After that, do
bundle install
and then fire up my rails server as below:
rails s
0I tried what you had suggested:-
But it did not work - My server fired up but could load my app - My patience was tested.
Uncommented -
require 'bootsnap/setup' # Speed up boot time by caching expensive operations. gem 'bootsnap', '>= 1.4.4', require: false and run
Bundle Install Fired up my server and my App was up running in seconds
This happened to me today as I was trying out Rails 6. On my local machine, I have Ruby version 2.7.0 installed, as well as Rails version 6.0.1. Turns out, I had just upgraded my Mac's OS to Catalina. The fix for me was to run in Terminal
xcode-select --install I ran this in my ~ directory, not sure if this will matter as the xcode installation is most likely global. After running this, I changed back to my new Rails app directory, ran bundle and everything installed without issue, including bootsnap and pg.
Hope this helps any Mac users who have recently upgraded their OS. Note, I was previously running Mojave and still needed to reinstall xcode, after having it installed already when I was running Mojave.
