#gem_platforms ⇒ Object
Attempt to detect the correct platform settings for the target gem environment.
In practice, this only makes a difference if different versions are available depending on platform, and only if the target gem environment has a radically different platform (i.e., jruby), so we just try to detect jruby and fall back to the current platforms (Gem.platforms) if we don’t detect it.
Returns
- String|Gem::Platform
-
returns an array of Gem::Platform-compatible
objects, i.e., Strings that are valid for Gem::Platform or actual Gem::Platform objects.
