在库中（您可以看到here）：

module.exports = function(accountSid, authToken, opts) {
    return new Twilio(accountSid, authToken, opts);
}

module.exports = Car将等效于export default Car
因此，您可以使用以下命令导入模块：

import twilio from "twilio";
//     ^ this will select default export

const client = twilio(YOUR_ACCOUNT_SID, YOUR_AUTH_TOKEN);

您可以执行以下操作：

import * as Twilio from 'twilio';

const YOUR_AUTH_TOKEN = process.env.TWILIO_AUTH_TOKEN;
const YOUR_ACCOUNT_SID = process.env.TWILIO_ACCOUNT_SID;

const client = Twilio(YOUR_ACCOUNT_SID, YOUR_AUTH_TOKEN);

client.messages
  .create({
     body: 'This is the ship that made the Kessel Run in fourteen parsecs?',
     from: '+15017122661',
     to: '+15558675310'
   })
  .then(message => console.log(message.sid));

确保正确安装twilio。
