RubyMine - ruby - what does [global] mean in rvm, should i use a global or non-global sdk

Question

When picking from a list of RVM versions, for many versions I see two versions, as in:

RVM:ruby-1.9.2-p180 [global]

plus also:

RVM:ruby-1.9.2-p180

Does it matter which I use?

Answer 1

Global in this case applies to gemsets. All gemsets under the installed 1.9.2-p180 version will be able to access gems installed to 1.9.2-p180@global.
