推荐答案
如果已安装AWS PowerShell模块，则尚未将其正确加载到当前会话中.我们将其识别为问题，因为您指定的错误意味着找不到给定的cmdlet.
If you have installed the AWS PowerShell Module, you haven't correctly loaded it into your current session. We're identifying this as the issue because the error you specified means that the given cmdlet can't be found.
首先通过以下任一选项验证模块是否已安装:
Verify first that the module is installed, by any of the options below:
将模块加载到现有会话中:(PowerShell v3和v4):
从文档中:
在PowerShell 4.0和更高版本中，Import-Module还会在Program Files文件夹中搜索已安装的模块，因此不必提供模块的完整路径.您可以运行以下命令来导入AWSPowerShell模块.在PowerShell 3.0和更高版本中，在模块中运行cmdlet还会自动将模块导入会话中.
In PowerShell 4.0 and later releases, Import-Module also searches the Program Files folder for installed modules, so it is not necessary to provide the full path to the module. You can run the following command to import the AWSPowerShell module. In PowerShell 3.0 and later, running a cmdlet in the module also automatically imports a module into your session.
要验证安装是否正确，请将以下命令添加到脚本的开头:
To verify correct installation, add the following command to the beginning of your script:
PS C:\> Import-Module AWSPowerShell
将模块加载到现有会话中:(PowerShell v2):
要验证安装是否正确，请将以下命令添加到脚本的开头:
To verify correct installation, add the following command to the beginning of your script:
PS C:\> Import-Module "C:\Program Files (x86)\AWS Tools\PowerShell\AWSPowerShell\AWSPowerShell.psd1"
使用Windows PowerShell for AWS Desktop Shortcut打开新会话:
一个快捷方式被添加到您的桌面，该快捷方式在将正确的模块加载到会话中的情况下启动PowerShell.如果安装成功，则应该显示此快捷方式，并且应该正确加载AWS PowerShell模块，而无需您付出额外的努力.
A shortcut is added to your desktop that starts PowerShell with the correct module loaded into the session. If your installation was successful, this shortcut should be present and should also correctly load the AWS PowerShell module without additional effort from you.
从文档中:
安装程序会创建一个名为Amazon Web Services的开始菜单组，
其中包含一个称为Windows PowerShell for AWS的快捷方式.为了
PowerShell 2.0，此快捷方式自动导入AWSPowerShell
模块，然后运行Initialize-AWSDefaults cmdlet.对于PowerShell
3.0中，每当您运行AWS cmdlet时，都会自动加载AWSPowerShell模块.因此，对于PowerShell 3.0，由
安装程序仅运行Initialize-AWSDefaults cmdlet.欲了解更多
有关Initialize-AWSDefaults的信息，请参阅使用AWS凭证.
The installer creates a Start Menu group called, Amazon Web Services,
which contains a shortcut called Windows PowerShell for AWS. For
PowerShell 2.0, this shortcut automatically imports the AWSPowerShell
module and then runs the Initialize-AWSDefaults cmdlet. For PowerShell
3.0, the AWSPowerShell module is loaded automatically whenever you run an AWS cmdlet. So, for PowerShell 3.0, the shortcut created by the
installer only runs the Initialize-AWSDefaults cmdlet. For more
information about Initialize-AWSDefaults, see Using AWS Credentials.
