How to fix Rspec installation in Rails 4 action
I started to read Rails 4 in action and found the methodologie really good. This book shows us the mechanism of how to code properly. You are in fact in a dev’s brain and see how he thinks about everything, which is perfect for people starting to code and how to get the best pratice.
I really recommend you to read this book and don’t be passive. Because you will only learn if you are trying to do it by your own!
I am writting this post because I had trouble with my Rspec installation. If you are in a rush, it was because I had the wrong rspec-rails version …
I- Rspec installation - trouble shooting
The book is from 2014 and gems versions are moving. I had an issue when I was trying to install the Rspec on my computer. I followed the infos on the gemfile …. but could not figure out what I had.
This is what I had when I was trying to install Rspec
$rails g rspec:install

I tried to uninstall rspec and the dependencies, researching on all sorts of forums, checked if spring was not the problem… I finally tried to search other projects on Github with the same name. I found one and inspected the gemfile (because I knew this was caused by the Gemfile). my old gemfile:
source 'https://rubygems.org'
git_source(:github) do |repo_name|
repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
"https://github.com/#{repo_name}.git"
end

end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]I finally found out that the version of Rspec-rails was not compatible with the last rails version. Because I simply remove the version of Rpsec gem 'rspec-rails' and I was able to install it with $rails g rspec:install
I hope to help those who were in the same trouble as I.
