Problem :

I am trying to execute the below script:

gem install rdoc --no-document

gem install bundle


 I have already added /srv/myuser/.gem/ruby/2.5.0/bin to the path so I was able to install the gems.

I can also find the bundle when I try to perform:

ls -ltrah /srv/myuser/.gem/ruby/2.5.0/bin

I have also tried to install the bundler but that is not helping the cause. Am I doing anything wrong here ?

The gem which bundle command is showing me nothing. The gem spec bundle command is showing it to me.

I also tried to install the bundler before running the bundle but the same issue as follows

“Can't find gem bundler (>= 0.a) with executable bundle (gem::gemnotfoundexception)”

 appears while executing below commands :

gem list bundle shows

bundle (0.0.1)
bundler (2.0.1)


Does anyone have any solution on my issue?

 Solution :

The Bundler version 2 have introduced the new feature to automatically use your version of Bundler which is specified in your Gemfile.lock of your project. So if you have the existing Gemfile.lock with the line like below at the bottom


Then the Bundler will try to run with the Bundler version < 2.0. Since you have just Bundler 2.0.1 (and the Rubygems >= 2.7.0) installed on your box, it is failing with the rather unhelpful error message.

To fix your issue, you must follow below approach :

·  You need to remove the lines from your Gemfile.lock and must use bundler 2.x everywhere from now on,

·   You can also try to install the bundler 1.x version with gem install bundler -v '< 2.0' to use your appropriate version as specified by the Gemfile.lock.
