The homebrew node recipe now (beginning with 0.8.0) comes with npm.
|
|
It appears you already have npm installed at #{modules_folder}/npm.
|
|
To use the npm that comes with this recipe,
|
|
first uninstall npm with `npm uninstall npm -g`.
|
|
Then run this command again.
|
|
|
|
If you would like to keep your installation of npm instead of
|
|
using the one provided with homebrew,
|
|
install the formula with the --without-npm option added.

Homebrew has NOT installed npm. We recommend the following method of

installation:
|
|
curl https://npmjs.org/install.sh | sh
|

After installing, add the following path to your NODE_PATH environment
|

variable to have npm libraries picked up:
|

#{modules_folder}
