virtualenv_create with options.

[devgeist42]

Currently, virtualenv_create does not accept any extra options. For packages that depend on python modules in homebrew/python, such as numpy, etc., passing --system-site-packages to virtualenv should be useful.

Will want @tdsmith's input on this.

I think we already add them if they're declared as dependencies.

[tdsmith]

Thanks for the comment. Declared dependencies should already be accessible from the virtualenv; that's handled here: https://github.com/Homebrew/brew/blob/master/Library/Homebrew/language/python.rb#L126

If it isn't working, please open a ticket.

I see. At the moment virtualenv_create only looks at formulae; python module dependencies are not accessible inside virtualenv. Is it be possible to make the python module deps available inside virtualenv?

[tdsmith]

I don't understand what you're suggesting isn't available.

Even if you have depends_on "numpy" => :python in your formula, numpy is not accessible in the virtualenv.

[tdsmith]

Oh, sure. It would be hard to make that work and modules should just be vendored as resources instead; maybe it should throw a warning.

I see. That's what I thought. Thanks!

[MikeMcQuaid]

@kyungminlee It's worth noted that depends_on "numpy" => :python is somewhat deprecated (and I've made a note to officially deprecate it).
