'Gemfile not found' after typing rails -v

Question

Noob here.

I recently installed rails following the instructions laid out here >> http://installrails.com/steps/install_rails

When I input rails -v in my root directory I get the rails version as expected:

I am typing...rails -v Rails 5.0.1

However, when I cd into my documents folder I am getting 'Gemfile not found' :

I am typing...cd documents

I am typing...rails -v

/Users/Matt/Documents/Gemfile not found

I tried to install rails inside the documents directory, but still received the same output:

I am typing...gem install rails

Successfully installed rails-5.0.1

Parsing documentation for rails-5.0.1

Done installing documentation for rails after 0 seconds

1 gem installed

I am typing...rails -v

/Users/Matt/Documents/Gemfile not found

I can't create any rails applications with rails new while inside my documents folder either. Here is my ruby load_path:

I am typing...irb

2.4.0 :001 > $LOAD_PATH

=> ["/Users/Matt/.rvm/gems/ruby-2.4.0@global/gems/did_you_mean-1.1.0/lib", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby/2.4.0", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby/2.4.0/x86_64-darwin15", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/site_ruby", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/vendor_ruby/2.4.0", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/vendor_ruby/2.4.0/x86_64- darwin15", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/vendor_ruby", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/2.4.0", "/Users/Matt/.rvm/rubies/ruby-2.4.0/lib/ruby/2.4.0/x86_64-darwin15"]

Thank you for the help!

Answer 1

It seems like you have a broken installation of ruby/rails.

Use RVM(Ruby Version Manager) to manage your ruby versions/installations. It is still good to use even if you are only using one version. Once RVM is installed, you can the install rails gem. It keeps everything clean so that you don't have to deal with paths etc.

Try the following to get your environment in 'rails' shape:

Install RVM

curl -sSL https://get.rvm.io | bash -s stable --ruby

Install Ruby(change the version to whatever you wish)

rvm install 2.3.1 

Set the default ruby version

rvm default use 2.3.1

Go to a directory where you keep your projects

cd /path/to/my/projects

Install rails gem

gem install rails 

Check rails version

rails -v

Create a new Project as a test

rails new test-project

Hopefully this works for you!

RVM can solve your problem, you can have several versions of ruby installed, what you should do is create a gemset per project.

To install it go to: https://rvm.io/rvm/install, use Install RVM stable with ruby.

After installing it, go to the directory where you want to create the new rails project and make the following commands:

rvm gemset create yourApp rvm gemset use yourAppName gem install rails rails new yourAppName

And you must do that for every project you want to create, this will help you to keep the appropriate version of ruby, rails, etc. For each project.
