Question

当我在knex中使用种子将csv文件中的数据添加到数据库时，我的种子无法读取csv文件，但是如果我独立运行文件csv该文件，则可以在下面将其作为代码读取。

>

var loader = require('csv-load-sync');
console.log(2);
var csv = loader('document.csv');
console.log(3);
// module.exports = csv;
console.log(csv);
exports.seed = function(knex, Promise) {
  console.log(csv);
  return knex('documents').del()
  .then(function () {
    return knex('documents').insert(csv);
  });
  console.log(csv);
};

如果我不通过种子运行文件运行：节点demo.js

console.log(1);
var loader = require('csv-load-sync');
console.log(2);
var csv = loader('./document.csv');
console.log(3);
module.exports = csv;
console.log(4);
console.log(module.exports);
