sendgrid sgmail.使用咖啡网流星对错误进行错误.作为纯JS的正常工作正常

Question

sgmail.send（msg）呼叫在我在咖啡中代码时会产生错误。如果我离开的是嵌入式JS，则可以正常工作。

这是错误：

Answer 1

我不认为const是您的问题。在Coffeescript中，您可以将它们删除。在JS中删除const不能破坏以前运行的代码（尽管添加它们可能可以）。这是您的样本转换为咖啡文字：

sgMail = require('@sendgrid/mail')
sgMail.setApiKey(process.env.SENDGRID_API_KEY)
msg = 
  to: '[e-mail]'
  from: '[e-mail]'
  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)

在这里您可以看到JavaScript转换为

错误看起来像无限循环或递归功能调用。

如果将JS代码转换为Coffeescript，请检查您的缩进，因为Coffeescript将其用于块而不是支撑。

如果您可以弄清楚错误来自哪个行，则可以发布该代码，以及该代码。
