In Version 1.3 and earlier of Bundler you couldn’t specify the patchlevel:
The
ruby
directive 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
ruby
directive,:patchlevel
is optional, as patchlevel releases are usually compatible and include important security fixes. The patchlevel option checks theRUBY_PATCHLEVEL
constant, and if not specified then bundler will simply ignore it.
So you can specify the patchlevel like this:
ruby '2.0.0', :patchlevel => '353'
