我开发了一个脚本，可以使用 .env 文件下载并安装 AWS CLI 和 Config。即使它已成功安装和配置，当我尝试将 s3 文件复制到服务器时，它无法下载该文件。当我在另一个 Powershell 会话中运行
aws --versionaws configure list我希望在一个触发器中自动执行整个过程：下载 AWS CLI、安装它以及将文件下载到服务器。如何从 s3 下载文件？是否需要刷新路径或帮助我解决此问题？
提前致谢！
错误：

看起来像是路径问题。安装 AWS CLI 时，系统/任何新进程的 PATH 都会更新，但 PATH 的更新不会自动应用于当前进程。
有多种方法可以解决此问题：
aws"C:\Program Files\Amazon\AWSCLIV2\aws.exe"Set-Alias -Name aws -Value "C:\Program Files\Amazon\AWSCLIV2\aws.exe"$env:Path += ";C:\Program Files\Amazon\AWSCLIV2"
