Bundle not working with rbenv

I'm trying to use bundler with rbenv. I has been working until today. The only thing I may have done to break it was gem pristine --all or gem cleanup ? When trying to install bundler i get the following error.

Antarrs-MacBook-Pro:some-app antarrbyrd$ sudo gem install bundler

when i do rbenv rehash or rbenv bundler on it get this error

update

I reinstalled rbenv via brew and now I get the following error when running bundle install.

The `bundle' command exists in these Ruby versions:
  2.1.5

Your installation is caught in a loop.

Change to a directory that is not your app, and that doesn't have a Gemfile.

Then do the usual gem install bundle (and use sudo if you need it)

Then change to your app directory, and do the usual bundle install.

Does that solve your issue?

If you need more help, can run these commands then paste the results in your question?

 $ command -v ruby
 $ command -v bundle
 $ ruby -v
 $ bundle -v

Look for any mismatch between the results and what you expect. This will help you track down what's happening. You may need to update your Gemfile Ruby version.

(Also, you may want to consider changing from rbenv to chruby because it's better IMHO with these kinds of path issues)

I got:

rbenv: bundle: command not found

The `bundle' command exists in these Ruby versions:
  2.3.0

after upgrade to Ruby 2.3.1

and it's solved by:

gem install rails

from working folder

gem install bundler

You need to reinstall bundler for each version of Ruby you use.

Reference: github issue

Try to use:

> bin/bundle

instead of

> bundle

I had the exact same issue and tried absolutely everything here and all over internet but the command that finally worked for me was:

gem update --system

If none of the other solutions work for you try this.

For some reason I could not install bundler on specific ruby versions, thus reinstalling bundler did nothing for me.

However I noticed how rbenv whence bundle specified that bundle was active in some ruby versions, but not others. If you look under the path for the gem without bundler (for me this was ~/.rbenv/versions/2.5.1/bin/) you will notice that it is not there. However under other versions that whence can recognise you will see the executable is there (for me it was there under ~/.rbenv/versions/2.3.1/bin/bundle).

Just copy the executable over from the working ruby version to the one that is broken. Then at the top of the file you will notice sha-bang is set to the other ruby version (for me this was #!/Users/myuser/.rbenv/versions/2.3.1/bin/ruby). Change the version path to the ruby version you want to fix and then it will all magically start working.

Here's what worked for me with a legacy project:

1. Set the proper ruby version via rbenv

   
   $ cd YOUR_PROJECT_DIRECTORY
   $ rbenv install 2.1.0
   $ rbenv local 2.1.0
   

2. If you still get an error when installing bundle, look for a PATH warning:

   
   $ gem install bundle
   WARNING:  You don't have /Users/lex/.gem/ruby/2.1.0/bin in your PATH,
   gem executables will not run.
   Successfully installed bundle-0.0.1
   1 gem installed
   

3. Update your PATH:

   
   $ PATH=/Users/lex/.gem/ruby/2.1.0/bin:$PATH
   

4. Try again:

   
   $ bundle install
   Fetching: bundler-1.11.2.gem (100%)
   HTTP GET https://bundler.rubygems.org/api/v1/dependencies
   HTTP 200 OK
   Fetching gem metadata from https://rubygems.org/
   . . .
   

Using sudo to install gems is generally not what you want to do.

Try setting ruby globally

rbenv global 2.3.1

I have a similar issue today. My issue was fixed as follows:

system dependencies
- rvenv
- ruby 2.5.0
- rails 5.1.6

check bundler version in Gemfile.lock

BUNDLED WITH
  1.17.3

install specific version of bundler

$ gem install bundler -v 1.17.3
Fetching bundler-1.17.3.gem
Successfully installed bundler-1.17.3
Parsing documentation for bundler-1.17.3
Done installing documentation for bundler after 3 seconds
1 gem installed

Hope this will help somebody.

For installing bundler with Ruby less than 2.3.0 use following command

gem install bundler -v '< 2'

I had a similar issue running Guard with Foreman. My original command to run it was:

bundle exec foreman run guard -c

This gave me these errors:

11:07:52 - INFO - Run all
11:07:52 - INFO - Running all specs
/Users/MyUser/.rbenv/versions/2.2.0/lib/ruby/2.2.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'bundler' (>= 0) among 146 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/MyUser/devel/o2/vesta/vendor/bundle/ruby/2.2.0', execute `gem env` for more information
        from /Users/MyUser/.rbenv/versions/2.2.0/lib/ruby/2.2.0/rubygems/dependency.rb:324:in `to_spec'
        from /Users/MyUser/.rbenv/versions/2.2.0/lib/ruby/2.2.0/rubygems/core_ext/kernel_gem.rb:64:in `gem'
        from /Users/MyUser/.rbenv/versions/2.2.0/bin/bundle:22:in `<main>'

The simple fix was to not use bundle exec with foreman but to use it against guard. e.g.

foreman run bundle exec guard -c

Hope this helps.

None of the provided answers worked for me, so I had to completely uninstall rbenv and everything related to Ruby and then just install Ruby 2.7.1 with Homebrew; brew install ruby.
