我在 mac 上执行此操作，在启动 localstack 之前，我运行了 pip install --upgrade localstack。然后，我做了localstack start。然后我得到了以下异常

我实际上检查了lsof -n -iTCP:4564 | grep LISTEN 是否有任何进程正在监听 4564，但没有返回任何内容。

【解决方案1】：

Try this:

DEBUG=1 localstack start

在报错之前的日志中你可能会发现一个路径包含：localstack.ddb.zip（替换下面的some_path）删除该文件并从 localstack/infra 中删除 dynamodb 包。

rm -f /var/folders/some_path/localstack.ddb.zip
rm -rf /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/localstack/infra/dynamodb/

现在您可以尝试重新启动 localstack。

此外：当我在 docker 中运行时，我看到了同样的问题，但我无法删除任何内容，因为容器是从每个 compose-up 的图像创建的。
