這是我定義函數并使用 module.exports 導出它們的地方class GITHelper extends Helper {addLatestReport(){  simpleGitPromise.addRemote(date,remote);    return simpleGitPromise.add('.')      .then(          (addSuccess) => {            console.log(addSuccess);          }, (failedAdd) => {            console.log('adding files failed');      });}commitLatestReport(){  console.log("Committing...");  return simpleGit.commit("Latest output from Automated UI Testing", "./output");}pushLatestReport() {    console.log('Pushing...');    return simpleGit.push(remote);}}module.exports = GITHelper;我需要在另一個節點依賴文件（mochawesome）中使用這個模塊var gitHelper = require('../../../helpers/GITHelper.js');然后我像這樣調用函數：async function gitSender(){ await gitHelper.addLatestReport(); await gitHelper.commitLatestReport(); await gitHelper.pushlatestReport(); console.log("Upload completed");}“類型錯誤：gitHelper.addLatestReport 不是函數”這些不是定義的函數嗎？它們沒有被正確導出嗎？
