我正在编写将文件写入 s3 的服务，但偶尔会遇到此MODULE_NOT_FOUND错误。消息是"Could not find API configuration s3-2006-03-01"。它似乎发生在集群中（多次调用这个函数都会出错，然后另一个请求不会出错），我在本地从未遇到过这个错误。

我没有将明确的配置引用传递给new AWS.S3()，但这似乎不是问题……如果您遇到/解决了这个问题，很想收到您的来信。

错误和堆栈如下：

}

.../node_modules/aws-sdk/clients/s3.js 代码如下（引用的文件都在，而且好像没有一直报错）：

require('../lib/node_loader');
var AWS = require('../lib/core');
var Service = AWS.Service;
var apiLoader = AWS.apiLoader;

apiLoader.services['s3'] = {};
AWS.S3 = Service.defineService('s3', ['2006-03-01']);
require('../lib/services/s3');
Object.defineProperty(apiLoader.services['s3'], '2006-03-01', {
  get: function get() {
    var model = require('../apis/s3-2006-03-01.min.json');
    model.paginators = require('../apis/s3-2006-03-01.paginators.json').pagination;
    model.waiters = require('../apis/s3-2006-03-01.waiters2.json').waiters;
    return model;
  },
  enumerable: true,
  configurable: true
});

module.exports = AWS.S3;

我的代码（/app/async/worker.js）调用了这个：

const AWS = require('aws-sdk');

function s3upload(file_location, upload_name, bucket, public = false) {
    return new BPromise(function(resolve, reject) {
        const s3 = new AWS.S3();    // STACK TRACE REFERENCES THIS LINE
        let body = fs.createReadStream(file_location);

        let upload_options = {
            Bucket: bucket,
            Key: upload_name,
            Body: body
        };

        if (public) {
            upload_options.ACL = 'public-read';
        }

        s3.upload(upload_options, function(err, data) {
            if (err) {
                return reject(err);
            }

            resolve(data.Location);
        });
    });
}
