I am trying to install Ruby & Rails on DigitalOcean droplet, I have downloaded ruby 2.5.1 with RVM but when I check version it says 2.31 and when I list available versions I get only 2.5.1.
I have tried rvm use 2.5.1 I got below problem
I fix it by running source ~/.rvm/scripts/rvm , then rvm use 2.5.1 and run bundle install, I get the following error,
can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
Below show the unstable issues faced from RVM and ruby versions
UPDATE
When I ssh into the server and run ruby -v, I get 2.5.1, then if I run
/bin/bash --login
I check ruby -v, its 2.5.1
install ruby 2.5.1 first, from your image it seems rvm already installed correctly
you just need to install it (it shows from your list command)
rvm install 2.5.1
# this to install version 2.5.1
rvm use 2.5.1
# active ruby 2.5.1
ruby -v
# check your version and make sure it said 2.5.1
to install bundler to your home directory use
# after you active ruby 2.5.1 then install bundler
gem install bundler
# my suggestion do not install with sudo
# in case you still has write problem below is other solution suggested [from here][1]
gem install bundler --user-install
This will install Bundler into your home directory. Note that you will need to append ~/.gem/ruby//bin to your $PATH variable to use bundle.

When I try to start my Rails server, I get the following error:
$ bundle exec rails s
Your Ruby version is 2.3.7, but your Gemfile specified ~> 2.3.8
I don't understand why that happens though, since I set Ruby to 2.3.8 both using Homebrew and using rbenv. 2.3.7 is the version of the system's ruby. I am using Mac OS 10.14.4.

I don't see anything here which would make me think it shouuld be using 2.3.7.
I'm not sure what else to try.
How does Bundler decide which version of Ruby to use, and how can I configure it to use either rbenv or my homebrew Ruby installation?
How about to try to use 'rvm'?
rvm install 2.4.2
This command will install another version of ruby, 2.4.2
And you can simply check the versions which all you have as
rvm list.
After this, run the version which you wish as the below,
rvm <version> or rvm use <version>
Hope this will help you!
Summary: The wrong version of bundler causes the problem. Use a ruby version manager to install the needed ruby version. Then install the correct version of the bundler gem for your project.
Details: In my case I'm running a rails example on github that required an older version of ruby and bundler and got the error described.
To manage my different ruby versions, I'm using ruby-install and chruby both installed with homebrew.
I followed these steps to resolve the problem on macOS Catalina v10.15.7:
Resolution steps
% ruby-install 2.4.1
# open a new shell so chruby will find 2.4.1
% chruby 2.4.1
% which ruby
/Users/richardlogwood/.rubies/ruby-2.4.1/bin/ruby
% gem install bundler:1.16.1
% which bundle
/Users/richardlogwood/.gem/ruby/2.4.1/bin/bundle
% cd (to the rails project directory)
# Note: it's a rails project so there was a binstub
# for bundler, hence `bin/bundler` in the project directory*
% bin/bundler install
% rake db:{create,migrate}
% bin/rails s
Before running the above steps, the error messages told me which version of ruby and bundler I needed to install. The system bundler was the wrong version (I'm on a mac) and the initial error message using that version gave me the error below. Only after installing the needed bundler gem (see above) was the correct ruby version resolved (see above).
Errors before resolution
% bundle install
Your Ruby version is 2.6.3, but your Gemfile specified 2.4.1
% which ruby
/Users/richardlogwood/.rubies/ruby-2.4.1/bin/ruby
% which bundle
/usr/bin/bundle
Note, the required bundler version was indicated by this error message:
Could not find 'bundler' (1.16.1) required by your ... /Gemfile.lock. (Gem::GemNotFoundException)
To update to the latest version installed on your system, run `bundle update --bundler`.
To install the missing version, run `gem install bundler:1.16.1`
I don't suggest using RVM instead of RBEnv. RBEnv is one of the most up-to-date solutions around, and most people stick with it.
Can you please try running gem update --system to update your bundler first.
Install Rbenv and run the following commands in your project directory to install 2.3.8:
rbenv install 2.3.8
rbenv local 2.3.8
bundle install --path=vendor/cache
I had rbenv installed and also installed Ruby manually at some point because of certain issues which I thought I cleaned up. But it seems I had /usr/local/bin/{bundle,bundler} still present which was evident when I did: which bundle that showed it's location not under shims (belonging to rbenv) so I simply had to remove these e.g. rm -rf /usr/local/bin/{bundle,bundler} and all was working again.
I am trying to run bundle on 2.1.10 ruby version. using rbenv and my local and global is both ruby 2.1.10 but everytime i try to server or bundle it says.
Your Ruby version is 2.3.3, but your Gemfile specified 2.1.10
what would be the best possible way to fix or figure out the problem.
Run rvm use 2.1.10 if you used rvm to install ruby
if it is not installed it will give you the instructions to do it:
Required ruby-2.1.10 is not installed.
To install do: 'rvm install "ruby-2.1.10"'
I have a problem when running bundle install in the root of sharetribe rails's project. It shows me this error message:
Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
I tried installing rvm and installing the 2.3.1 version required to run this project but nothing changes and it still throwing this output.
Have anyone faced this problem before ?
Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
Steps to resolve this issue
1)rvm install ruby-2.3.1
2)gem install bundler
3)rvm use ruby-2.3.1
4)Bundle install
Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
If you run command ruby -v you can see that you have installed Ruby 2.4.0, when you look at the first line in your Gemfile specifies that you want to use Ruby 2.3.1.
You can do either install Ruby 2.3.1 or replace the first line in your Gemfile to with Ruby 2.4.0.
What does it say when you run bundle env in the terminal?
Is it the same ruby version?
I tried gem install bundler one time i had the same problem and bundle updated and worked.
You can read more about it here.
Good luck!
I'm trying to bundle install a ruby project in Git Bash but I'm getting the above message.
ruby -v
ruby 2.2.4p230 (2015-12-16 revision 53155) [i836-mingw32]
gem -v
2.3.0
New to Ruby so its really frustrating. I'm trying to do the project below
http://www.viralrails.com/?p=25
This happens because you are specifying a Ruby version in your Gemfile (2.3.0) and this version is not installed or is not the current or default version.
Don't remove the line ruby '2.3.0' as someone said above. You app may have dependencies to this version. Do the following:
1) Check if you have Ruby 2.3.0 installed. If you are using rvm this may be done by
rvm list
and if you are using rbenv by
rbenv versions
2) If you don't have this Ruby version in your list of installed versions, then install it by issuing the following command
rvm install 2.3.0
and if you are using rbenv by
rbenv install 2.3.0
3) If you already had Ruby 2.3.0 installed or completed step 2 above, enter your app directory and issue the following command
rvm use 2.3.0
and if you are using rbenv by
rbenv local 2.3.0
Then run
bundle install
and I believe things will be ok.
Hope it helps!
Install bundler after installing ruby 2.4.0.
gem install bundler
If you installed bundler before installing ruby 2.4.0 then you should reinstall bundler or update it.
Also if the above command didn't work.
gem update bundler
Somehow my rails installation hides itself successfully...
I have:
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]
rvm 1.10.0-pre
gem 1.8.10
and I try to install rails:
sudo gem install rails
it works fine:
Successfully installed rails-3.1.3
1 gem installed
Installing ri documentation for rails-3.1.3...
Installing RDoc documentation for rails-3.1.3...
when I do:
rails - v
I get
The program 'rails' is currently not installed. You can install it by typing:
sudo apt-get install rails
Also, when I do
rake
in a rails app root directory, I get:
Missing the Rails gem. Please `gem install -v= rails`, update your
RAILS_GEM_VERSION setting in config/environment.rb for the Rails version
you do have installed, or comment out RAILS_GEM_VERSION to use the
latest version installed.
executing
gem install -v= rails
raises an error:
ERROR: While executing gem ... (ArgumentError)
Illformed requirement ["="]
So apparently it is sitting somewhere and cannot be seen by my environment. I guess installing via apt-get is not an option as I don't want to confuse gem...
Any ideas?
Cheers

Do not use sudo.
Just gem install rails
Use RVM instead of the packaged ruby/gems distribution. http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
