意外的关键字或标识符.ts(1434)

Question

我有以下代码尝试从本地计算机读取文件并将其上传到 AWS s3 云服务：

import AWS from 'aws-sdk';
import fs, { ReadStream } from "fs";
import path from "path";

class Uploads {

  static const bucketName = "myappllbuck";
  static const s3 = new AWS.S3({ apiVersion: '2006-03-01' });
  static const filePath = "/home/s/img2.png";

  static const uploadParams: {
    Bucket: string;
    Key: string;
    Body: string | ReadStream;
    ContentType: any; ACL: string
  } = {
      Bucket: this.bucketName,
      Key: '',
      Body: '',
      ContentType: null,
      ACL: 'public-read',
    };

  static const fileStream  = fs.createReadStream(this.filePath);

  
  fileStream.on('error', function(err) {
    console.log('File Error', err);
  });
   this.uploadParams.Body = this.fileStream;
   this.uploadParams.Key = path.basename(filePath);
   this.uploadParams.ContentType = 'image/png';
   this.uploadParams.ACL = 'public-read';
}

但是我收到以下错误 @ fileStream.on()行：

Unexpected keyword or identifier.ts(1434)
Member 'fileStream' implicitly has an 'any' type.ts(7008)

以及以下错误@ this.UploadParams. 代码行：

Unexpected token. A constructor, method, accessor, or property was expected.ts(1068)
Object is possibly 'undefined'.ts(2532)

从fileStream.on('error', function(err) {开始的代码仍然在 class 中。确保在运行此代码之前关闭 class 声明。
