Guard has problems with gem versions

I ma following railstutorial.org and I am trying to make Guard work. I have a problem when I try to run any tests from guard console:

15:10:04 - INFO - Run all
15:10:04 - INFO - Running: all tests
Warning: You're using Rubygems 1.8.23 with Spring. Upgrade to at least Rubygems 2.1.0 and run `gem pristine --all` for better startup performance.
Could not find json-1.8.1 in any of the sources
Run `bundle install` to install missing gems.

I have json in version 1.8.1:

$ gem list | grep json
json (1.8.1)
multi_json (1.10.1)

I updated rubygems to version 2.4.2 nad ran gem pristine --all but id does not change anything, even the warning still exists.

I tried killing spring, restarting everything, etc - no help.

Solution

  • Ok, I resolved this. I deleted all json entries in Gemfile.lock. Then I ran bundle install and it works!
