问题
I am sitting here in an airport, came up with something that I'd like to try, but I won't have time to sudo port install if macports downloads-compiles-downloads-compiles. If it downloaded everything, however, then I can have it compile on the plane.
How can I cache a port's dependencies but compile and install later?
回答1:
I would use
sudo port fetch \( {packagename} or rdepof:{packagename} \) and not installed
rdepof: recursively lists all dependencies of your package (including the dependencies of the dependencies themselves)
and not installed excludes all packages you have already installed.
