我正在尝试使用以下命令在本地启动 Dynamodb

yarn start:beta

哪个调用此脚本

source ./scripts/prod-assumerole.sh && SLS_DEBUG=* sls offline start --region us-east-1 --stage local-beta --inMemory true --migrate true  --seed local --noAuth true --dontPrintOutput

问题

此调用失败，并出现本文末尾链接的错误。如果我导航到 localhost:8000/shell，aws 本地已加载，但没有表。

以前的尝试

  • 我们尝试过使用不同版本的java。当前版本是 13.0.2
  • 我们尝试删除 node_modules 文件夹和 .dynamodb 文件夹，然后使用 yarn 重新安装它们
  • 我们确认已安装无服务器（版本信息如下）
Serverless: Running "serverless" installed locally (in service node_modules)
Framework Core: 1.54.0
Plugin: 3.1.2
SDK: 2.1.2
Components Core: 1.1.1
Components CLI: 1.4.0

问题

有谁知道可能导致此错误的原因？
或者有没有人有任何故障排除的想法？

我们发现我不小心修改了我的 /etc/hosts 文件并删除了对 localhost 的引用。
在我重新添加以下内容后，我能够毫无问题地启动 dynamodblocal：

127.0.0.1    localhost
255.255.255.255 broadcasthost
::1       localhost

我们通过在连接和不连接我的 vpn 的情况下测试启动 dynamodblocal 发现了这个问题。它在未连接时工作，但在连接时失败（并且 localhost:3000 无法解析并显示错误）。这促使我们检查确实缺少这些引用的“etc/hosts”文件。
