更新八度：链接安装

Question

I have OSX 10.10.5 with Octave 3.4.0 running (installed, who knows how, I did it a million different ways through port, file extraction, ftp, homebrew…). I tried to update my Programme ( brew install octave or sudo port install octave ) and Terminal spits out:

Warning: octave-3.8.2 already installed, it's just not linked

Okay, great. So I have a better programme somewhere installed. What now? How on earth am I supposed to “just link ” the newer installation?

Answer 1

If you install octave with Homebrew and it doesn't link it it should tell you why. You can force Homebrew to link octave with

$ brew link --overwrite octave

You can also add the --dry-run option to check and see what Homebrew will do to link octave

$ brew link --overwrite --dry-run octave

A possible reason for Homebrew not linking octave is that you've installed it by another method, MacPorts for instance. It is not recommended that you use both Homebrew and MacPorts on the same system.
