I can set ruby version in Gemfile as follows:
ruby '2.0.0' But what if I want to have a particular version as 2.0.0-p353?
When I add it to Gemfile, I get:
Your Ruby version is 2.0.0, but your `Gemfile` specified 2.0.0-p353 Is it even possible to set a particular version?

There are several ways to specify gem versions: Use a specific version: gem "name-of-gem", "1.0" . You can find specific versions on Rubygems.org (provided that's the source you”re using) by searching for your gem and looking at the “Versions” listed. Use a version operator: gem "name-of-gem", ">1.0" .
Set Ruby version with rvm on Mac To set a default Ruby version with rvm, enter rvm --default use 3.0. 0 on the command line. To switch to the system ruby, enter rvm use system . To switch back to the default, rvm default .
In Version 1.3 and earlier of Bundler you couldn’t specify the patchlevel:
The
rubydirective explicitly leaves out the ability to specify a patch level. Ruby patches often include important bug and security fixes and are extremely compatible.
This changed in version 1.5, the docs now say:
In the
rubydirective,:patchlevelis optional, as patchlevel releases are usually compatible and include important security fixes. The patchlevel option checks theRUBY_PATCHLEVELconstant, and if not specified then bundler will simply ignore it.
So you can specify the patchlevel like this:
ruby '2.0.0', :patchlevel => '353' If anyone is looking to be reminded of how to NOT specify a minor version, (yeah call me a noob) you could do:
ruby ">=2.2" which would allow 'bundle install' call with ruby 2.2.4.
