javascriptのrequireに変数を渡す

Question

私はjavascriptとnode.jsを使用しています。これはエラーになります

var countryName = "Turkey"; 
var jsonPath = '../'+countryName+'/PersonalDetails.json'; 
console.log(jsonPath); 
var PersonalDetails = require(jsonPath); 

：私は私のコードに次の行を持って見つけることができませんモジュールの../Turkey/PersonalDetails.json "

が、私は

var PersonalDetails = require('../Turkey/PersonalDetails.json'); 

それを使用する場合正常に動作します。私は何が欠けていますか？

参照のために私のjsonファイルも添付してください。あなたはパスリンケを定義することができ

    "fields":[ 
       { 
        "fieldType":"Radio", 
        "fieldLabel":"Relevance to the transaction :", 
        "disclosureField":"" , 
        "fieldList":["One carrying out the transaction","One on behalf of him/her the transaction is carried out","Indirect Relevance"]

この：私はあなたのコードをコピーし、それが正常に動作します

var jsonPath = require(__dirname + '/../' + countryName + '/PersonalDetails.json');
