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

to install bundler that matches with your Gemfile.lock use:

gem install bundler -v "$(grep -A 1 "BUNDLED WITH" Gemfile.lock | tail -n 1)"
