无。 Node.js 0.4.7中的观察方法。 用以下文字取代198线的监视功能:

watch = function(source, base) {
return fs.stat(source, function(err, prevStats) {
  if (err) throw err;
  return fs.watchFile(source, function(curr, prev) {
    return fs.stat(source, function(err, stats) {
      if (err) throw err;
      if (stats.size === prevStats.size && stats.mtime.getTime() === prevStats.mtime.getTime()) {
        return;
      }
      prevStats = stats;
      return fs.readFile(source, function(err, code) {
        if (err) throw err;
        return compileScript(source, code.toString(), base);
      });
    });
  });
});
};

如果您升至0.6,可尝试Jitter。 它的单一用途指挥线效用是<代码>coffee -cw之前使用的。 咖啡厅 1.1.3. 此外,它有一些额外的东西,如汇编失败时的“Grownl”通知。

Here s a watchscript I wrote after having same experience with coffeescript -w option not working. It finds and watches .coffee, .less, .jade files for change and triggers their corresponding compilers in response. Generates colored output for easy detection of when the compilation failed.
