Rubygems: Make "Unresolved specs during Gem::Specification.reset" warning more useful

[matkoniecz]

"WARN: Unresolved specs during Gem::Specification.reset" is not very useful - it appears without mentioning what requested given gem version and it appears in situation where wanted gem version is available.

$ rspec spec/case_insensitive_parser_spec.rb 
WARN: Unresolved specs during Gem::Specification.reset:
      diff-lcs (< 2.0, >= 1.2.0)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.

despite that

$ gem list | grep lcs
diff-lcs (1.3, 1.2.5)

It was already reported as #1350, but it was closed by reporter despite lack of change.

I'm having a problem or would like to suggest a feature.

My current problem is confusing error message.

This issue is related to:

• [ ] Network problems
• [ ] Installing a library
• [ ] Publishing a library
• [ ] The command line gem
• [X] Other

Here are my current environment details:

$ gem env version
2.6.12

I will abide by the code of conduct.

From what I understand, this means that you have more than one version of the listed gems installed on your system, and RSpec is unsure which to use.

Is it a correct interpretation? If yes, then maybe "Unresolved specs as multiple gem versions match spec" would be more useful?

I had the exactly same issue. I cleaned up all diff-lcs versions and then bundled again and it worked.
A more specific message would be much more helpful and less stressful.

[Bhavikpatel576]

Can you tell us how you found all the diff-lcs versions?

[andretf]

$ gem uninstall diff-lcs
then choose to uninstall all versions

[vynessa]

I used bundle clean --force and then ran bundle install to reinstall gems. Fixed the issue here.

Related also to #1070 found by other googling.

[revolter]

I get:

WARN: Unresolved specs during Gem::Specification.reset:
      CFPropertyList (< 4.0, >= 2.3.3)
WARN: Clearing out unresolved specs.

and no solution from here fixed it.

Maybe you should try removing the gem which is causing you problem

i tried but still getting error

[deivid-rodriguez]

I'm sorry you're having issues, how did you install msfconsole?

[aniket19992610]

I'm sorry you're having issues, how did you install msfconsole?

Pre-installed with kali linux OS.
Now it's resolve but sometimes it gives same error. Don't know why.

[deivid-rodriguez]

Weird... If it's causing issues, they should happen every time, not intermittently :thinking:.

[sampl3x]

I got the same issue on the latest Kali Linux:

WARN: Unresolved or ambiguous specs during Gem::Specification.reset:
reline (>= 0)
Available/installed versions of this gem:
- 0.1.5
WARN: Clearing out unresolved specs. Try 'gem cleanup '
Please report a bug if this causes problems.

[deivid-rodriguez]

Is there any chance you could provide a Dockerfile using msfconsole on Kali Linux where this issue can be observed?

[aniket19992610]

Weird... If it's causing issues, they should happen every time, not intermittently 🤔.

Yes, so strange. I think its because of virtual machine. I am running kali on vmware pro. So i think its issue.

use apt update and apt upgrade. My problem solve with this only but not completely solved. Sometimes it gives same error.

[0x4F6D616E]

This happened to me after an upgrade.
Here's a fix for that warning:
First remove any default reline gems:
sudo rm /usr/lib/ruby/gems/2.7.0/specifications/default/reline-0.1.*

Then install the current default reline version(0.1.3) that works fine with Metasploit, and set it to the default reline:
sudo gem install reline --default -v 0.1.3

You should be good now.
