Meteor.js和npm

Question

所以我使用流星包meteorhacks:npm爲了在我的流星代碼中使用npm包。所以我有一個模板：

Template.upload.events({ 
    'submit form': function(event){ 
     var file1 = document.getElementById("file1").files; 

     var file2 = $('[name=file1]').val(); 
     //console.log(file1[0].type); 

     var reader = new FileReader(); 
     reader.onload = function(event) { 
      var contents = event.target.result; 
      Meteor.call("saveFileinFolder",contents); 
      //console.log(contents); 

     }; 

這是流星方法我打電話：

Meteor.methods({ 
    saveFileinFolder: function (content){ 
     var nodeFS = Meteor.npmRequire('node-fs'); 
     var fs = new nodeFS({version:'0.1.7'}); 
     console.log(content); 
    } 
}); 

我試圖使用節點包節點-FS爲了保存文件到一個文件夾，但我不斷收到錯誤：

你誤解了使用meteorhacks的方式：npm。你需要把你想要的版本號到名爲packages.json文件：

{「節點-FS」：「0.1.7」}

然後重新啓動流星，它會安裝節點包您滿意。然後在您的代碼中，按照慣例require繼續，只需使用Meteor.npmRequire。您將獲得與節點中的require相同的對象。
