javascript - TypeError : csv. fromPath 不是函数(将 csv 文件转换为 sha1 脚本)

Question

我正在尝试执行读取 CSV 文件的示例脚本。然后将数据进行SHA1哈希。我从这个 git 复制了示例:

https://gist.github.com/cdurth/6735c82cd11c5a057bd4

我收到此错误:

C:\Users\test\Desktop\convert\csvParseToSha1.js:14
 .fromPath(inputFile)
  ^

TypeError: csv.fromPath is not a function
    at Object.<anonymous> (C:\Users\Nope\Desktop\convert\csvParseToSha1.js:14:3)

    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:74:12)
    at internal/main/run_main_module.js:18:47

示例代码:

var fs = require('fs');
var csv = require("fast-csv");
var sha1 = require('sha1');

var inputFile = 'emailList.csv';
var outputFile = 'sha1List.csv';

var csvStream = csv.format({headers: false}),
    writableStream = fs.createWriteStream(outputFile);

csvStream.pipe(writableStream);

csv
 .fromPath(inputFile)
 .on("data", function(data){
   var hashed = sha1(data[0])
   csvStream.write([hashed]);
 })
 .on("end", function(){
     csvStream.end();
     console.log("done");
 });

fast-csv版本是4.1.3

对于“fast-csv”版本 >= 3.0.0 :- fromPath 已弃用
