I am using Capistrano to deploy my rails app to ec2 VM. I am following along with this tutorial https://gist.github.com/ThomasBush/584dc1e999b34177dd4436c5edb1b24d
I am using ruby version 2.6.5
Capistrano Log:
DEBUG [3b5b580d] Command: cd /home/deploy/editorial_board/releases/20210607071516 && ( export RBENV_ROOT="$HOME/.rbenv" RBENV_VERSION="2.6.5" ; $HOME/.rbenv/bin/rbenv exec bundle install --jobs 4 --quiet )
DEBUG [3b5b580d] Your Ruby version is 2.6.5, but your Gemfile specified 2.7.1
I have checked ruby -v in my local machine and on ec2 VM and i am getting my ruby version 2.6.5
Also in my gemfile specified version is 2.6.5
In .ruby-version file version is 2.6.5
In Capfile set :rbenv_ruby, '2.6.5'
I am not getting where 2.7.1 is specified, and how to get it deployed
delete Gemfile.lock and run bundle install again.
And check if you installed rbenv on your ec2 instance.

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'm working on a project in ruby 2.1.10. it should be using rails 4.0.13.
I'm using rbenv.
I've installed everything, I believe. I ran bundle install for the project. eventually I got it to run.
However, now I get:
turlingdrome$ rails
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
turlingdrome$ gem install rails -v 4.0.13
Successfully installed rails-4.0.13
Parsing documentation for rails-4.0.13
Done installing documentation for rails after 1 seconds
1 gem installed
turlingdrome$ which rails
/Users/brianp/.rbenv/shims/rails
turlingdrome$ rails -v
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
turlingdrome$ ruby -v
ruby 2.1.10p492 (2016-04-01 revision 54464) [x86_64-darwin16.0]
in case it matters, I'm on a mac running 10.12.6
ETA from comment:
turlingdrome$ bundle exec rails -v
Rails 4.0.13
so, bundle exec lets me run rails. rbenv exec rails seems to work too.
So, the problem seems to be in the shim!
Rehash the shims:
rbenv rehash
Now you should be able to run only rails without bundle exec or rbenv exec.
I am getting ' Your Ruby version is 2.3.3, but your Gemfile specified 2.0.0' when I am trying to deploy with Capistrano.
my gemfile specifying 2.3.3
ruby "2.3.3"
00:27 bundler:install
01 /usr/local/rvm/bin/rvm 2.3.3 do bundle install --path /var/www/mypath/shared/bundle --without development test --deployment --quiet
01 Warning, new version of rvm available '1.29.1', you are using older version '1.29.0'.
01 You can disable this warning with: echo rvm_autoupdate_flag=0 >> ~/.rvmrc
01 You can enable auto-update with: echo rvm_autoupdate_flag=2 >> ~/.rvmrc
01 Your Ruby version is 2.3.3, but your Gemfile specified 2.0.0
Don't know what the problem is from looking at this, but here is how I would debug it.
Check your Gemfile and Gemfile.lock and verify it is showing 2.3.3. Also Capistrano pulls directly from the repository rather than uploading your local files so verify your Gemfile and Gemfile.lock on the remote machine have the right versions. If they don't, verify you have committed the latest Gemfile and Gemfile.lock and pushed them up to your repository. You can also try just running bundle on the remote machine to take Capistrano out of the equation.
I am trying to install gems for a new Rails project using bundler:
$ bundle install --path
I've set my local Ruby version to 2.3.1 using rbenv, but bundler is still using my system Ruby (2.0.0).
$ rbenv local
2.3.1
$ echo $PATH
/Users/jenniferpierce/.rbenv/shims:/Users/jenniferpierce/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/PostgreSQL/9.5/bin
$ which ruby
/Users/jenniferpierce/.rbenv/shims/ruby
$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
$ bundle install --path
Your Ruby version is 2.0.0, but your Gemfile specified 2.3.1
My bash profile includes:
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
I've run:
$ rbenv rehash
and restarted my terminal. Maybe I'm missing something super obvious? Any ideas would be appreciated.
To add to this, in my case, I first had to run rbenv rehash and then install the bundler gem, and then re-run bundle install. Without all of those steps, it kept the same old Ruby version.
You should be able to just run bundle install without the --path. I believe --path allows you to specify a different path than the one in your system, but if you modified your bash profile as you suggested, there is no need for that.
Also, if you just changed your ruby version for the local folder, you should run a gem install bundler.
I am trying to start deploying a rails app with mina gem only I can not seem to get it initialized.
As you can see here, I am not doing anything out of the ordinary, I have added mina to my gem list, it installs fine, but the executable is not found.
➜ trackitall git:(master) ✗ bin/bundle install
40 other gems
Using mina 0.3.4
Bundle complete! 41 Gemfile dependencies, 143 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
➜ trackitall git:(master) ✗ mina init
zsh: command not found: mina
➜ trackitall git:(master) ✗
I am using rbenv with ruby 2.1.5 for this project on macOS 10.10.3. Also there is no mina shim in the ~/.rbenv/shims folder. As far as I understand, rbenv here should be all the executables for your specific ruby env.
I was using rbenv and had the same problem where mina was not being found. All I had to do was:
rbenv rehash
and then
mina init
Ok, noobie mistake.
The problem was that mina is not in the environment. So you can either run
bundle execute mina for executing mina in your current gem environment
or run rbenv rehash and then mina should be available in your path
