find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)

Question

I used sudo bundle install and that might be the cause of the issue?

Now I have:

• gem -v 2.6.14
• ruby -v

Answer 1

Adding to the many answers, my problem stemmed from wanting to use the docker's ruby as a base, but then using rbenv on top. This screws up a lot of things.

I fixed it in this case by:

• The Gemfile.lock version did need updating - changing the "BUNDLED WITH" to the latest version did at one point change the error message, so may have been required
• in .bash_profile or .bashrc, unsetting the environment variables:

unset GEM_HOME
unset BUNDLE_PATH

After that, rbenv worked fine. Not sure how those env vars were getting loaded in the first place...

Answer 2

I downgraded ruby from 2.5.x to 2.4.x in my particular case.

Answer 3

I had to do rake clean --force. Then did gem install rake and so forth.

Answer 4

Update:

According @noraj's answer and @Niels Kristian's comment, the following command should do the job.

gem update --system
bundle install

I wrote this in case someone gets into an issue like mine.

gem install bundler shows that everythings installs well.

Fetching: bundler-1.16.0.gem (100%)
Successfully installed bundler-1.16.0
Parsing documentation for bundler-1.16.0

When I typed bundle there was an error:

/Users/nikkov/.rvm/gems/ruby-2.4.0/bin/bundle:23:in `load': cannot load such file -- /Users/nikkov/.rvm/rubies/ruby-2.4.0/lib/ruby/gems/2.4.0/gems/bundler-1.16.0/exe/bundle (LoadError)

    from /Users/nikkov/.rvm/gems/ruby-2.4.0/bin/ruby_executable_hooks:15:in `<main>'

And in the folder /Users/nikkov/.rvm/rubies/ruby-2.4.0/lib/ruby/gems/2.4.0/gems/ there wasn't a bundler-1.16.0 folder.

I fixed this with sudo gem install bundler

Answer 5

In my case the above suggestions did not work for me. Mine was little different scenario.

When i tried installing bundler using gem install bundler .. But i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

then i tried using sudo gem install bundler then i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
  You don't have write permissions for the /usr/bin directory.

then i tried with sudo gem install bundler -n /usr/local/bin ( Just /usr/bin dint work in my case ).

And then successfully installed bundler

EDIT: I use MacOS, maybe /usr/bin din't work for me for that reason (https://stackoverflow.com/a/34989655/3786657 comment )

Answer 6

I had the same issue today. I solve this problem by removing any PATH in .bashrc for older rvm.
