You are using an old or stdlib version of json gem

[GJHmf]

Hi all,

I've seen the following issue mentioned in another thread a few days
ago amongst other problems, but the solution for this issue (to me)
didn't seem to be addressed.

I recently ran a test on my Ruby 1.9.2-p290 environment, and was
presented with the following error when I ran a test script:

You are using an old or stdlib version of json gem
Please upgrade to the recent version by adding this to your
Gemfile:

gem 'json', '~> 1.7.7'


This issue continued when I created a completely fresh Ruby 1.9.3-p392
environment, running on Windows XP (don't ask). What confuses me is
that even when I have json 1.7.7 or 1.8.0 installed (gem list is
pasted below), I still get this message when I run my test. It's not
really affecting my test results, but the warning is just rather
annoying to see each time.

Which Gemfile do I need to add this version into, and where would it
be located?


Thanks,


Graham

You'd need to be using bundler for a gemfile to make a difference.

From other recent postings (and I think an Stack Overflow question) the error message seems to be coming from multi_json what might work is to use a slightly oder version of it.   Try this from the command line

  gem uninstall multi_json

  gem install multi_json --version 1.7.2

then try running things and see if you no longer get the warning
