PowerShell无法识别安装在同一脚本中的AWS CLI

Question

我已经使用powershell脚本安装了aws-cli

$command = "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12"
Invoke-Expression $command
Invoke-WebRequest -Uri "https://awscli.amazonaws.com/AWSCLIV2.msi" -Outfile C:AWSCLIV2.msi
$arguments = "/i `"C:AWSCLIV2.msi`" /quiet"
Start-Process msiexec.exe -ArgumentList $arguments -Wait
aws --version

当我尝试打印aws --version时，会出现以下错误。

aws : The term 'aws' is not recognized as the name of a cmdlet, function, 
script file, or operable program. Check the spelling of the name, or if a path 
was included, verify that the path is correct and try again.

我在安装aws-cli:后添加了以下行，从而解决了这个问题

$env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine")

完整代码：

$command = "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12"
Invoke-Expression $command
Invoke-WebRequest -Uri "https://awscli.amazonaws.com/AWSCLIV2.msi" -Outfile C:AWSCLIV2.msi
$arguments = "/i `"C:AWSCLIV2.msi`" /quiet"
Start-Process msiexec.exe -ArgumentList $arguments -Wait
$env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine")
aws --version
aws s3 ls
