CoffeeScript:安装后无输出

Question

我运行的是 Ubuntu 13.04，安装后使用:

$ sudo npm install -g coffee-script

..带输出..

npm http GET https://registry.npmjs.org/coffee-script
npm http 304 https://registry.npmjs.org/coffee-script
/usr/local/bin/coffee -> /usr/local/lib/node_modules/coffee-script/bin/coffee
/usr/local/bin/cake -> /usr/local/lib/node_modules/coffee-script/bin/cake

任何命令都不会产生任何结果:

$ coffee js.coffee 
$ coffee -v
$ coffee GiveMeSomeCoffeePlease

我确认它存在:

$ which coffee 
/usr/local/bin/coffee

该文件有一些内容:

$ cat `which coffee`
#!/usr/bin/env node

var path = require('path');
var fs   = require('fs');
var lib  = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');

require(lib + '/coffee-script/command').run();

还尝试了可在我的笔记本电脑上运行的版本 1.6.1。不过在这台电脑上没有区别。有什么想法吗？

我终于找到了解决办法。我在 Ubuntu 上安装了 node 包，这是完全不同的:

Amateur Packet Radio Node program (transitional package) The existing node package has been renamed to ax25-node. This transitional package exists to ease the upgrade path for existing users.

我继续安装了 nodejs 包。但似乎它并没有完全创建正确的绑定(bind)，我可以运行 nodejs 但不能运行 node。所以我为它创建了一个别名，现在 CoffeeScript 运行得很好!

cd/usr/bin; sudo ln -s nodejs 节点
