解析服务器和 mongodb 问题

Question

我正在尝试为我的快速应用程序设置解析服务器的本地安装。这是我所做的：

npm install -g parse-server mongodb-runner

然后：

mongodb-runner start

这触发了这个错误：

  Starting a MongoDB deployment to test against...{ HTTPError: Response code 403 (Forbidden)

因此，我决定在 mongodb.com 上创建一个集群，而不是在本地运行 mongodb。然后我尝试运行这个连接到集群的命令（当然我用正确的值替换了 APP_ID、MASTER_KEY 和 MONGODB_DATABASE_URI）：

parse-server --appId APP_ID --masterKey MASTER_KEY --databaseURI MONGODB_DATABASE_URI

这是我得到的错误：

/usr/local/lib/node_modules/parse-server/lib/ParseServer.js:225
      throw err;
      ^

我已经在谷歌上搜索了这么久，我无法弄清楚这一点。parse-server 和 mongodb 都是最新的。说 parse-server 是 3.0.0 而 mongodb 是 3.1.8

看起来 mongodb-runner 第一次从 mongodb.org 下载一些文件，并且根据此线程，这些链接对于某些版本已更改。MONGODB_VERSION因此，在运行 mongodb-runner 时通过设置环境变量来尝试不同的 mongo 版本：

MONGODB_VERSION=3.4.1 mongodb-runner
