TSort::Cyclic: topological sort failed when running bundle install after new gem dep

[PragTob]

Hello everyone,

at first thank you for making bundler. It really makes developer life so much easier and is one of my favorite things about ruby :-)

To the problem:
Just now I released a new version of the furoshiki gem (with the help of bundler and rake release) which we use in shoes4. Building the gem locally worked and also using the local gem from shoes4. Also gem install furoshiki works.

However when I tried to update the gem in the shoes gemspec (be it via >=, ~> ot just the version) I get this error. A branch of shoes4 with the tried update is here.

Here is my bundle env output (there is no Gemfile.lock as I tried to delete that to see if it would make it work..).

Here is a comparison of the two furoshiki versions - it might be that we/I messed something up but I can not seem to locate it.

Any help highly appreciated, thanks =)

Welllll... like it says, you have a circular dependency. :)

Shoes depends on furoshiki. But in your gisted output, furoshiki also depends on shoes! So neither one can ever be installed, because the other one has to be installed first.

dohhh >_>

Thank you very much Andre, sometimes I don't know what's happening.

Although I'd appreciate an error message that is more clear about the circular dependency situation as I can not seet that from topological sort failed. Any pointers on where in the code base I could implement that so I could fix up a PR?

we just implemented one, and it's already in master. :) thanks for the offer, though! if you'd like to help with something else, there's a great set of possible things to be implemented right now:

• Warn if using a version of bundler older than that specified in the lockfile
• Provide an option to auto-bundle before commands if bundle check is failing.
• Plugin system
• Stop saving options passed to install
• Support private access credentials for sources
• add support for --gemfile and --path to bundle package
