TypeError: csv.fromPath is not a function (convert csv file to sha1 script)

TypeError: csv.fromPath is not a function (convert csv file to sha1 script)

我正在尝试执行读取 CSV 文件的示例脚本。然后将数据做成 SHA1 散列。我从这个 git:

复制了样本

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

我收到这个错误:

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

TypeError: csv.fromPath is not a function

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 版本为 4.1.3

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

https://github.com/C2FO/fast-csv/blob/master/History.md#v300

所以我已经将 csv.fromPath() 更改为 csv.parseFile()

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

现在我明白了:

internal/fs/utils.js:535
    throw new ERR_INVALID_ARG_TYPE(propName, ['string', 'Buffer', 'URL'], path);
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string or an instance of Buffer or URL. Received undefined
