如何更新咖啡脚本？

Question

当我尝试通过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)

我不知道错误是怎么回事。

然后我检查了版本，coffee -v是 1.6.1 和node -vv0.6.12。

根据官方网站（http://coffeescript.org/）的最新版本是1.6.3，所以我想更新coffee的npm update -g coffee-script，但是这个失败也。

npm WARN coffee-script@1.6.1 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

在我的咖啡脚本目录中，只有一个文件box_wrapper.coffee.

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

我尝试重新安装coffee，所以我这样做了。

$ sudo npm -g rm coffee
npm WARN Not installed in /usr/local/lib/node_modules coffee
$ coffee -v
CoffeeScript version 1.6.1

我无法删除coffee。我也试过这样。

$ 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.

并且npm-debug.log是一个空白文件。

问题是 npmjs 存储库没有 1.6.3 而是 1.6.1。我会在这里假设，但你的错误的原因是你的代码，而不是 CoffeeScript：

    } catch (e) {
      if (e.code !== 'ENOENT') {
        throw e;
      }
    }
  };

以上表明 ife.code与ENOENTthen 抛出错误不完全相同，在您的情况下是：

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)

我会检查文件fs.js和/或恢复您对代码所做的最后更改。CoffeScript 做得很好，问题出在其他地方。

对于可能实际更新他们的 CoffeScript 的人

如果你真的想使用最新的 CoffeScript，那么安装它的方法是使用：

npm install -g http://github.com/jashkenas/coffee-script/tarball/master

这将安装最新的 CoffeScript，如果你想要 1.6.3 版本，那么你应该使用：

npm install -g http://github.com/jashkenas/coffee-script/tarball/1.6.3

将 替换为1.6.3您喜欢的 CoffeScript 版本。

Answer 2

由于旧nodejs版本而发生错误。Ubuntu 12.04、13.04 默认nodejs包是 version 0.6.x。

我将nodejs版本更新为v0.10.20这样，然后问题就解决了。

sudo apt-get update
sudo apt-get install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

我按照这里的说明进行操作。 https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager
