为了在虚拟环境下开发AI工具，项目经理给我们一个项目启动环境的安装guide，总共10步非常简单，其中有几步如下，计划10步总消耗Effort：0.5H

§ curl -sSL https://install.python-poetry.org | python -
§ cd ./ProjectDir/Lib/

+ curl -sSL https://install.python-poetry.org| python -
+ ~~~~
+ CategoryInfo : InvalidArgument: (:) [Invoke-WebRequest], ParameterBindingException
+ FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.Commands.InvokeWebRequestCommand
