Getting this error while running rails s.How to resolve it
commenting the content of gemfile and updating ruby and rails to a latest stable version will solve most of the errors.
for me I reinstalled ruby and rails using the steps provided at:

I'm running into this issue on an M1 laptop for a rails project I'm running bundle install, how to resolve this?
I tried running
gem install ffi -v '1.9.25' -- --with-cflags="-Wno-error=implicit-function-declaration"
Which installed the gem successfully, but when I try to run rake db:migrate this error comes up
rake db:migrate

An error occurred while installing sqlite3 (1.3.11), and Bundler cannot continue.

Any ideas how I can fix this?
You need to install sqlite3 first sudo apt-get install libsqlite3-dev
Have you tried googling your error?
Here's an answer to the same error you're getting.
Unable to install gem - Failed to build gem native extension - cannot load such file -- mkmf (LoadError)
The solution is not with sqlite3. It's most likely your -dev package. If you're on Linux try this -
sudo apt-get install ruby-dev
For Mac, try this
brew install ruby-dev
I keep getting following:

remote: An error occurred while installing spree_core (3.0.4), and Bundler cannot
remote: continue.
remote: Make sure that `gem install spree_core -v '3.0.4'` succeeds before bundling.
when I run
gem install spree_code -v '3.0.4'
it is successful and afterwards when I run git push heroku master again I get the exact same error.
rbenv versions
shows following:
2.2.2 (set by /Users/Martijn/.rbenv/version)
Heroku needs the ruby version defined in the Gemfile, like:
ruby "2.2.1". More info: https://devcenter.heroku.com/articles/ruby-versions.
When I type
rails _4.2.0.rc2_ new hello_app
I get this error

I tried installing railsties 4.2.0.rc2 using
gem install railties --pre
If you want try to use new rails version, you need execute
gem install rails --pre
instead of
gem install railties --pre
Railties its core of Rails framework but not in all. See official documentation for more information.
I re-installed rails completely
gem uninstall railties -v 4.2.0.rc2
sudo gem install rails -v 4.2.0.rc2
and that solved it.
I'm going through the rails tutorial atm. (I'm a beginner so bear with me.)
As you can see below, when I try and install the rubygems using 'bundle install', I get the error message saying that I need to make sure 'gem install json -v '1.8.1' succeeds before I try again.
But when I try and sudo gem install json -v '1.8.1', I get the

If I'm asking a stupid question, or if I've left out any necessary info, just let me know. I'm new to this -- CodeAcademy & RailsForZombies are the extent of my knowledge.

So running this worked for me:
sudo apt-get install ruby1.9.1-dev
Suppose the -dev package was needed?
If #BenLawton answer doesn't work try this (work for me on Ubuntu 16.04):
sudo apt-get install ruby-full
