Installing TeX from source is weird and gross, requires a lot of patches,
|
||
|
|
and only builds 32-bit (and thus can't use Homebrew deps on Snow Leopard.)
|
||
|
|
|
||
|
|
We recommend using a MacTeX distribution:
|
||
|
|
http://www.tug.org/mactex/
|
||
|
|
EOS
|
||
|
|
|
||
|
|
when 'mercurial', 'hg' then abort <<-EOS.undent
|
||
|
|
Mercurial can be install thusly:
|
||
|
|
brew install pip && pip install mercurial
|
||
|
|
EOS
|
||
|
|
|
||
|
|
when 'npm' then abort <<-EOS.undent
|
||
|
|
npm can be installed thusly by following the instructions at
|
||
|
|
http://npmjs.org/
|
||
|
|
|
||
|
|
To do it in one line, use this command:
|
||
|
|
curl http://npmjs.org/install.sh | sudo sh
|
||
|
|
EOS
|
||
|
|
|
||
|
|
when 'setuptools' then abort <<-EOS.undent
|
||
|
|
When working with a Homebrew-built Python, distribute is preferred
|
||
|
|
over setuptools, and can be used as the prerequisite for pip.
|
||
|
|
|
||
|
|
Install distribute using:
|
||
|
|
brew install distribute
|
||
|
|
EOS
|
||
|
|
end
|
||
|
|
end
