我在将Get-WmiObject添加到用于远程推送软件的某些代码时遇到错误。我希望代码在继续之前检查当前安装的应用程序，但当我运行它时，遇到错误：
获取WmiObject：术语“Get-WmiObject”未被识别为cmdlet、函数、脚本文件或可操作程序的名称。请检查名称的拼写，或者如果包含路径，请验证路径是否正确，然后重试。At C：\code\getwmiobj.ps1：1 char：1 + Get-WmiObject-Class“win32_Product”-ComputerName“$computer”|......+ ~~~~~~~~~~~~~~ +类别信息：找不到对象：（Get-WmiObject：字符串）[]，命令未找到异常+完全限定的错误ID：未找到命令异常
