I got a following error when I tried to watch coffee scripts by coffee -o js -cw coffee.

/usr/local/lib/node_modules/coffee-script/lib/coffee-script/command.js:321

        throw e;

              ^

Error: watch Unknown system errno 28

    at errnoException (fs.js:636:11)

    at FSWatcher.start (fs.js:663:11)

    at Object.watch (fs.js:691:11)

    at /usr/local/lib/node_modules/coffee-script/lib/coffee-script/command.js:287:27

    at Object.oncomplete (/usr/local/lib/node_modules/coffee-script/lib/coffee-script/command.js:100:11)

I have no idea what is going with error.

Then I checked the versions, coffee -v is 1.6.1 and node -v is v0.6.12.

According the official site( http://coffeescript.org/ ) the latest version is 1.6.3, so I wanted update coffee by npm update -g coffee-script, but this fails also.

npm WARN [email protected] package.json: bugs['name'] should probably be bugs['url']

npm http GET https://registry.npmjs.org/coffee-script

npm http 304 https://registry.npmjs.org/coffee-script

How can I update coffee script?

Edit 2013/10/11

In my coffee script directory there is only one file box_wrapper.coffee.

$ ->

  $("body").children().wrap ->

    "<div id='#{$(@).attr "id"}_box' class='wrapper'/>"

Edit 2013/10/16

I tried to re-install coffee, so I've done like this.

$ sudo npm -g rm coffee

npm WARN Not installed in /usr/local/lib/node_modules coffee

$ coffee -v

CoffeeScript version 1.6.1

I can't remove coffee. And I tried also like this.

$ sudo apt-get remove npm

$ npm -v

-bash: /usr/bin/npm: No such file or directory

$ sudo apt-get install npm

$ npm -v

1.1.4

$ sudo npm -g install coffee



# I omit a lot of `GET` parts.
