使用node.js读取csv文件

我正在尝试使用node.js读取csv文件。我收到错误“输入意外结束”。以下是我使用的代码：

const csv = require('csv-parser');
const fs = require('fs');
const fast = require('fast-csv');


fs.createReadStream('filename.csv')
.pipe(csv())
.on('data', (row) => {
    console.log(row);
})
.on('end', (row) => {
    console.log('CSV file successfully processed');

我已使用代码from here。

当我使用“ node sample.js”在命令模式下运行以上代码时，以下是错误：

C:\Users\learningsql\Desktop\filter>node sample.js
C:\Users\learningsql\Desktop\filter\sample.js:12
    console.log('CSV file successfully processed');

感谢您的帮助。谢谢。

尝试一下：

const csv = require('csv-parser');
const fs = require('fs');
const fast = require('fast-csv');


    fs.createReadStream('accounts.csv')
        .pipe(csv())
        .on('data', (row) => {
            console.log(row);
        })
        .on('end', () => {
            console.log('CSV file successfully processed')
        });
