javascript - Node.js 导出函数错误

Question

我是编写 Node.js 模块的新手。我正在按照以下方式编写模块，

a.js

var fs = require("fs") ;
var util = require("util") ;
var mime = require("mime") ;

module.exports = {
  getDataUri: function (image, callback ) {
    var data = fs.readFileSync(image).toString("base64") ;
    var dataUri =  util.format("data:%s;base64;%s", mime.lookup(image), data) ;
    return callback(dataUri) ;
  }
};

b.js

var d = require('./a.js') ;

function getDiff(image1, image2, callback) {
  d.getDataUri(image1, function (d1) {
    d.getDataUri(image2, function (d2) {
      if (d1==d2) {
        return callback(true) ;
      }
      else {
        return callback(false) ;
      }
    }) ;
  }) ;
} ;

getDiff('/Users/sarthakmunshi/Desktop/Print/27274510-Geek-head-logo-template-Stock-Vector.jpg ',
'/Users/sarthakmunshi/Desktop/Print/27274510-Geek-head-logo-template-Stock-Vector.jpg ', function(res) {
  console.log(res) ;
}) ;

但是，当我运行 b.js 时，我收到一个奇怪的错误，

$ node b.js

    fs.js:438
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^
Error: ENOENT, no such file or directory '/Users/sarthakmunshi/Desktop/Print/27274510-Geek-head-logo-template-Stock-Vector.jpg '

    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

我无法纠正此错误。需要帮助。

抱歉给您带来麻烦，我通过消除路径末尾的空格解决了这个问题。我觉得自己很蠢。
