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

[zulhfreelancer]

I'm new to rbenv (was using RVM for long time). Today I do clean uninstall of my RVM and install rbenv. I managed to install Ruby 2.5.1 without any issues.

But when I try to run bundle install for a project today, I got the following error:

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

Seems like something is broken with my bundler installation but I'm not sure what is wrong. Running gem install bundler with sudo doesn't solve the problem. I tried running rbenv rehash as well but it didn't work.

Here is the full trace:

How to fix this issue?

Note: I'm using OSX 10.12.6

[hsbt]

Can you try with gem i bundler -v 1.17.3 and bundle i on your project directory?

[PaoloVecchi]

That did the trick for me on a Debian 8

[zulhfreelancer]

@hsbt that worked for me. Thanks!

[noraj]

@zulhfreelancer @hsbt anwser here: https://bundler.io/blog/2019/01/04/an-update-on-the-bundler-2-release.html

[bdesmero]

Thank you!

[Danasekar]

Worked for me. Thanks!

[montdidier]

Probably the correct answer should be to upgrade ruby gems gem upgrade --system '2.7.9' at a bare minimum as the addresses a number of CVE also. Bundler 2.0.1 will magically worked after that too.

Thanks @montdidier - it should be update not upgrade:

gem update --system '2.7.9'

[Gibbo3771]

Can you try with gem i bundler -v 1.17.3 and bundle i on your project directory?

Worked for me on MacOS. Thanks!

  System Version:   macOS 10.14.3 (18D109)
  Kernel Version:   Darwin 18.2.0

[TeBoring]

The problem occurs again for bundler 2.0.2. Same fix?

[TeBoring]

gem update --system '2.7.9' fixes my issue.

[tangyumeng]

Can you try with gem i bundler -v 1.17.3 and bundle i on your project directory?

MacOS 10.14.4 should use gem update --system '3.0' and bundle i

[gsum]

Check the bundler version on Gemfile.lock
cat Gemfile.lock | grep -A 1 "BUNDLED"
That will give bundler version, something like this
BUNDLED WITH 2.0.1
Then install that specific version of bundler
gem install bundler -v '2.0.1'

[hsbt]

See https://bundler.io/blog/2019/05/14/solutions-for-cant-find-gem-bundler-with-executable-bundle.html

[oslivan]

I tried all the methods and it didn't work. So I deleted Gemfile.lock and then execute bundle install, I compare Gemfile.lock via gitdiff，As @gsum said，Gemfile.lock exist BUNDLED WITH 2.0.1, just install the corresponding bundle version.

[promisepreston]

The issue is that RubyGems cannot find an executable bundle for the bundler gem on the system

To fix it, first run

gem install bundler

if you don't have bundler version 2 installed locally, then run

gem update --system

That's all

I hope this helps

[RussellKsing]

Works for me, thank you!! @hsbt

[aswanimanav]

Can you try with gem i bundler -v 1.17.3 and bundle i on your project directory?

when I type in bundle i, I get 'Could not locate Gemfile'.
