Error Installing appium_lib with Ruby v2.4.2 Due to JSON

[PatrickDuncan]

Hello we're trying to install appium_lib v9.6.1 (bundle install) with Ruby v2.4.2-2 and we're getting an error with json v2.1.0 (and 1.8.7):

An error occurred while installing json (2.1.0), and Bundler cannot continue.
Make sure that `gem install json -v '2.1.0'` succeeds before bundling.

In Gemfile:
  appium_lib was resolved to 9.6.1, which depends on
    json

We've followed #4462 to no avail.

Right now we're using Ruby 2.3.3 and everything is running smoothly,

I don't think this issue relates to Bundler, are you able to install the json gem with gem install json -v '2.1.0'?

[PatrickDuncan]

@colby-swandale I was thinking that as well, but I wanted to follow suit with #4462

[colby-swandale]

#4462 isn't really a bundler issue either so we're not really able to help unless bundler is specifically the reason why the gem cannot be installed.

@PatrickDuncan Were you able to resolve your issue?

[PatrickDuncan]

I will post it in the json repo. Thanks.
