--- TEMPLATE END ----------------------------------------------------------------

Unfortunately, an unexpected error occurred, and Bundler cannot continue.

[deivid-rodriguez]

Loading YAML inside your Gemfile is a possible culprit. If you replace that with an explicit list of gems, does it work? Also, can you give a little more information? You haven't explained anything, not even what command you run.

[haider8645]

I am no ruby expert, just the user. For me, it seems that the error happens after the bundle install command is called. See below log. Rest of the log is the same as the one copied by priyanka.

The versions on my pc are:
gem --version
3.1.2
ruby --version
ruby 2.7.0p0 (2019-12-25 revision 647ee6f) [x86_64-linux-gnu]

2022-12-29 09:36:15 +0100: running

Thank you @haider8645 . Thank you for your reply @deivid-rodriguez. The error persists during the bundle installation. Since i am also not an ruby expert so being user hard to tell what went wrong . I even manually tried to update the system with gem update --system bundle update --bundler . but no luck .

[deivid-rodriguez]

But where are these errors coming from? Can you at least explain to me what you were trying to do when you run into this error? Specifically, you are the user of which software when you get this error? It could be any tool that uses Ruby under the hood, knowing that would be a start.

[haider8645]

@deivid-rodriguez We use a tool autoproj which uses bundler. Since we do know the inner workings, I created an issue on the autoproj with a mention of this issue so that someone can collaborate with you for a fix

[deivid-rodriguez]

Alright, thank you!

[doudou]

autoproj developer here. We only call bundler install under the hood. I'll be trying to get a Gemfile that makes it easy to reproduce the problem.

[Priyanka328]

Thank you @doudou .

Loading YAML inside your Gemfile is a possible culprit

@deivid-rodriguez. This is the issue. I forgot I was doing this in autoproj's own Gemfile.

Can you explain what's the problem here ? Can I use some bare file reading instead (i.e. File.readlines ?)

[deivid-rodriguez]

I'm not fully sure how the problem is being triggered in this particular case, I could have a closer look if I can reproduce the problem. Were you able to confirm the problem and that removing loading of yaml fixes it?

Anyways, the generic gist of the issue is that yaml is actually a gem, and we you require it, it gets activated as a gem. Bundler does not expect any gems to be activated while it evaluates the Gemfile, the Gemfile should declare dependencies, but not use them. This is one gotcha of having a dynamic manifest format like Gemfile, a prize to pay in exchange for the flexibility it brings.

On top of this, Bundler actually uses yaml internally as well, so that's another source of potential conflicts.

Using File.readlines should be ok, File.readlines is part of Ruby and I doubt it will ever be extracted to a gem.

[deivid-rodriguez]

This is interesting by the way. It would be interesting to bisect which Bundler version started having this issue.

[doudou]

Were you able to confirm the problem and that removing loading of yaml fixes it?

I did not go that far ... And should have. Removing the yaml bits does not solve the issue. If bundler requires yaml, won't require "yaml" in the Gemfile just reuse whatever version is already loaded ?

Currently, this Gemfile:

source "https://rubygems.org"
ruby "2.7.5" if respond_to?(:ruby)
gem "autoproj", ">= 2.0.0"
gem "utilrb", ">= 3.0.1"

Triggers the bug consistently on Ubuntu 20.04, BrightBox Ruby packages. ruby 2.7.5p203 (2021-11-24 revision f69aeb8314) [x86_64-linux-gnu] and bundler 2.4.1.

Just run vagrant up on the following Vagrantfile to trigger the bug (the .txt is here to please github):
