meteor - SendGrid sgMail.send 使用咖啡脚本流星的错误。作为纯 JS 工作正常

问题描述

当我在 Coffee 中编码时，sgMail.send(msg) 调用会产生错误。如果我离开的是嵌入式 js，它可以正常工作。

这是错误：

解决方案

我不认为consts 是你的问题。在 Coffeescript 中，您可以删除它们。在 JS 中删除const不能破坏以前运行的代码（尽管添加它们可以）。这是您转换为咖啡脚本的示例：

sgMail = require('@sendgrid/mail')
sgMail.setApiKey(process.env.SENDGRID_API_KEY)
msg = 
  to: 'test@example.com'
  from: 'test@example.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(msg)

在这里你可以看到它转换成的 javascript

该错误看起来像一个无限循环或递归函数调用。

如果您将 JS 代码转换为 Coffeescript，请检查您的缩进，因为 Coffeescript 将其用于块而不是大括号。

如果您可以找出错误来自哪一行，您可以发布该代码以及调用它的位置。
