Error Report

Questions

Please fill out answers to these questions, it'll help us figure out why things are going wrong.

• What did you do?

  I ran the command /usr/local/rbenv/versions/2.3.3/bin/bundle install

• What did you expect to happen?

  I expected Bundler to install successfully

• What happened instead?

  Instead, what happened was, I received the error below after bundler failed.

• Have you tried any solutions posted on similar issues in our issue tracker, stack overflow, or google?

  I haven't found any posted solutions but after a series of trial and error, I noticed that it is happening when Rails attempts to install a new em via the Gemfile. We are in a classroom with 20 students and are receiving this error with 5/15 on what should be identical environments. On 4 of the 5 machines having issues, if we list gems previously used in other projects bundle install works fine. Anytime we add a new gem we receive the error listed below with Gzip. The same 4 machines can install gems directly using "gem install bootstrap..." etc. and then when listed in the Gemfile it works fine. 1 of the 5 machines will not run bundle install no matter what we do. Brand new project with nothing added to the Gemfile other than the default.... still receiving the same error.

• Have you read our issues document, https://github.com/bundler/bundler/blob/master/doc/contributing/ISSUES.md?

BUNDLED WITH

[colby-swandale]

It looks like the information that Bundler is trying to pull from RubyGems.org is corrupt. Do you have a proxy that is caching traffic?

We'll also need to add a friendly error for this exception.

[colby-swandale]

I recommend you check any caching or proxy servers but i have added in a mitigation in #6264 that should prevent this error from rising in future Bundler releases.

[chrishickman]

Thanks a lot for the quick reply, I really appreciate it! We did determine that it only happens at work so I will see if something is being cached that I am unaware of and try again at work. Thanks again.
