Fastlane failed to run pod install



I didn’t change any circle.yml or fastfile recently, but this morning I got this error. Anybody know what’s going wrong here?

Hi Sarun,

This looks like an issue with Rubygems that I’ve seen on the Ubuntu containers. It’s a bug with recent versions of Rubygems and certain combinations of Rubygems and Bundler. I’ll bring this to the attention of our OS X team. As a workaround, can you try seeing if this fixes the error?

sudo gem update --system 2.4.8
gem uninstall bundler
gem install bundler


Hi Sarun,
A follow-up question: could you please installing a newer version of rubygems in your build? Something like this should do it:

    - gem update --system

We are very sorry for the trouble, and we hope to fix this soon. We would really appreciate your help debugging this.


Unfortunately seeing the same error, with the workarounds


I do have the same kind of problem:

[08:10:20]: $ make sort-project
[08:10:20]: ▸ bundle exec synx -p -e "Vendor" project.xcodeproj
[08:10:20]: ▸ /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.12.3/lib/bundler/rubygems_integration.rb:373:in `block in replace_bin_path': can't find executable bundle (Gem::Exception)

[08:10:20]: ▸ make: *** [sort-project] Error 1

My circle.yml already contained:

    - sudo gem update --system
    - sudo gem install bundler

My last successful build was on May 6. The next build on May 10 failed. Successful builds do not build anymore.

Edit: Using RubyGems 2.4.8 as suggested by Eric does not work better.


I “successfully” turned my build back to green.

I now use RubyGems 2.6.1 and Bundler 1.12.1.

Don’t ask me why those two specific versions. I don’t know.


Hi, Sarun.

I encountered the same problem with fastlane, like

bundle exec fastlane myCustomAction
-> bundle exec pod install
-> same error occured!!

and I wrote as follows in fastlane/Fastfile,

  cocoapods(use_bundle_exec: false)

It seems that calling bundle exec pod install during fastlane action causes error.

I hope my answer help you.


I also just got this with fastlane. The answer provided helped.


this answer helps me a lot! thanks!
