  let toArr;
  if (isDevelopmentMode()) {
    const mailList = process.env.REACT_APP_RECIPIENT_MAIL;
    console.log(mailList);
    toArr = mailList.split(',');
  } else {
    toArr = Array.isArray(to) ? to : [to];
  }
  const toAddrs = toArr.map(toAddr => ({
    emailAddress: {

要使新添加的 env 变量可用，您需要停止 React 服务器并使用npm start重新启动它。
