node.js - 如何纠正此错误“TypeError：EthereumTransaction 不是构造函数”？

Question

如何纠正这种类型的错误？这是进行交易的代码，还添加了在终端收到的错误。

var transaction = new EthereumTransaction(rawTransaction)

^TypeError: EthereumTransaction is not a constructor

这是我的代码：

   var privateKeySender = '*************************************'
   var privateKeySenderHex = new Buffer(privateKeySender, 'hex')
   var transaction = new EthereumTransaction(rawTransaction)
   transaction.sign(privateKeySenderHex)


   $ node index.js
   C:\Users\asus\Desktop\projectFolder\index.js:43
   var transaction = new EthereumTransaction(rawTransaction)
                  ^
     TypeError: EthereumTransaction is not a constructor
