Amazon Mechanical Turk 命令行工具 - 发生了 JNI 错误

Question

我正在尝试安装并使用 Amazon Mechanical Turk 命令行工具，我刚刚从https://requester.mturk.com/developer/tools/clt

我正在尝试从 Windows 10 中的管理员命令提示符运行它们。

当我尝试 getBalance 脚本时，出现以下错误：

c:\mypath\aws-mturk-clt\aws-mturk-clt-1.3.4>bin\getBalance
Error: A JNI error has occurred, please check your installation and try again

错误消息告诉我检查我的安装，但实际上没有什么可安装的。
