Meteor-CollectionFS createReadStream()错误: FS.Utility.safeStream需要NodeJS流

const { Meteor } = require('meteor/meteor');
const { CollectionFS } = require('meteor/cfs:standard-packages');
const fs = require('fs');

// 创建一个 CollectionFS 集合
const FileStore = new CollectionFS('files', {
  stores: [new FS.Store.GridFS('myFiles')]
});

// 插入文件
const file = '/path/to/your/file.txt';
const fileObj = new FS.File(fs.readFileSync(file));
FileStore.insert(fileObj, { filename: 'file.txt' }, (err, fileRecord) => {
  if (err) {
    console.error('Error inserting file:', err);
    return;
  }

  // 创建可读流
  const readStream = FileStore.createReadStream(fileRecord._id);

  // 处理流数据
  readStream.on('data', (chunk) => {
    console.log('Received chunk:', chunk);
  });

  readStream.on('end', () => {
    console.log('Stream ended');
  });

  readStream.on('error', (err) => {
    console.error('Stream error:', err);
  });
});
