如何让 TextMate 看到“需要”编译时 CoffeeScript 中的表达式？

当在 TextMate 中编写 CoffeeScript 并想要使用第三方 Javascript 库（如 jQuery 或 Raphael）时，需要添加一个“require”，如下所示：

$ = require 'jquery'

当使用 coffee -c myfile.coffee 时，效果很好命令行，但在尝试编译时在 TextMate 包中失败，并出现以下错误：

Error: Cannot find module 'jquery'
at Function._resolveFilename (module.js:317:11)
at Function._load (module.js:262:25)
at require (module.js:346:19)
at Object. (.:3:7)
at Object. (.:4:4)
at Module._compile (module.js:402:26)
at Object.run (/usr/lib/node_modules/coffee-script/lib/coffee-script.js:62:19)
at /usr/lib/node_modules/coffee-script/lib/command.js:120:29
at Socket. (/usr/lib/node_modules/coffee-script/lib/command.js:154:14)
at Socket.emit (events.js:61:17)

在此示例中，代码全部位于项目根目录的同一目录中。

当指定以下内容时也会发生同样的情况：

$ = require 'jquery.js'

其他人如何使用 TextMate 包在 CoffeeScript 中进行编译？对于我来说，除了最琐碎的代码之外，这似乎都是一个阻碍。除了语法突出显示之外，这肯定是这个包中最重要的部分之一吗？

When writing CoffeeScript in TextMate and wanting to use a 3rd party Javascript library like jQuery or Raphael there is a need to add a "require" like so:

$ = require 'jquery'

This works fine when using coffee -c myfile.coffee from the commandline, but fails in the TextMate bundle when trying to compile with this error:

Error: Cannot find module 'jquery'
at Function._resolveFilename (module.js:317:11)
at Function._load (module.js:262:25)
at require (module.js:346:19)
at Object. (.:3:7)
at Object. (.:4:4)
at Module._compile (module.js:402:26)
at Object.run (/usr/lib/node_modules/coffee-script/lib/coffee-script.js:62:19)
at /usr/lib/node_modules/coffee-script/lib/command.js:120:29
at Socket. (/usr/lib/node_modules/coffee-script/lib/command.js:154:14)
at Socket.emit (events.js:61:17)

In this example, the code is all in the same directory at the root of the project.

The same occurs when specifying:

$ = require 'jquery.js'

How are other people compiling in CoffeeScript with the TextMate bundle? This would seem to be a showstopper to me for anything but the most trivial code. Apart from syntax highlighting, surely this is one of the most important parts of this bundle?

您已点击“运行”命令 (⌘R)，相当于 coffee myfile.coffee。

您需要“编译并显示 JS”(⌘B)，相当于 coffee -c --print --bare myfile.coffee。这应该会打开一个带有编译输出的窗口

var $;
$ = require('jquery');

至于像 jQuery 和 Raphael 这样的 require 库，我希望您理解 require 只是一个用于加载模块的运行时函数；它没有编译时意义。您可能来自 C++ 或 Java 等带有“链接器”的语言。另一方面，在 CoffeeScript 中，代码一次被编译为 JavaScript 文件，并且 JavaScript 文件被单独加载到运行时环境（无论是浏览器还是 Node.js 等框架）。

You've hit the "Run" command (⌘R), equivalent to coffee myfile.coffee.

You want "Compile and Display JS" (⌘B), equivalent to coffee -c --print --bare myfile.coffee. This should open up a window with the compiled output

var $;
$ = require('jquery');

As to require-ing libraries like jQuery and Raphael, I hope you understand that require is just a runtime function for loading modules; it has no compile-time meaning. You may be coming from a language like C++ or Java where there's a "linker." In CoffeeScript, on the other hand, code is compiled to JavaScript one file at a time, and JavaScript files are loaded individually into the runtime environment (be it a browser or a framework like Node.js).
