TypeError：无法读取未定义的属性'isMultiple'（在Windows控制台上通过nodejs使用sendgrid）

Question

我一直在尝试通过Windows控制台上的nodeJs通过sendgrid发送电子邮件。我尝试使用sendgrid教程安装它：

echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
echo "sendgrid.env" >> .gitignore
source ./sendgrid.env

当我输入“ source ./sendgrid.env”时，Windows控制台无法识别该命令。之后，我尝试改用setx命令，现在控制台显示此错误日志：

(node:23300) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'isMultiple' of undefined

使用的代码段：

// using SendGrid's v3 Node.js Library
// https://github.com/sendgrid/sendgrid-nodejs
const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
  to: '***@gmail.com',
  from: '***@gmail.com',
  subject: 'Sending with SendGrid is Fun',
  text: 'and easy to do anywhere, even with Node.js',
  html: '<strong>and easy to do anywhere, even with Node.js</strong>',
};
sgMail.send();

Answer 1

我知道这已经很晚了，但是您需要发送信息：更改sgMail.send()至sgMail.send(msg)。

Answer 2

在nativescript js上有相同的错误。
