在PowerShell控制台中，$PROFILE变量是[string]。为什么在VS代码中不是[string]？

PS C:\> $PROFILE
C:\Users\pwatson2\Documents\PowerShell\Microsoft.PowerShell_profile.ps1
PS C:\> $PROFILE.GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     String                                   System.Object

PS C:\> $PSVersionTable.PSVersion.ToString()
7.1.5

在VS代码终端中，它是一个[PSCustomObject]。

更新2：

以下是VSCode PowerShell扩展启动时TERMINAL窗口中的输出。配置文件脚本如下所示。运行CurrentUserAllHosts脚本时，$PROFILE为NULL。这些脚本都不会设置$PROFILE的值。
有两个问题。
当调用其中一个非用户配置文件脚本（可能是AllUsersAllHosts）时，脚本的路径似乎没有使用正确放置的QUOTATION MARK字符。
当CurrentUserAllHosts脚本运行时，$PROFILE为NULL。

=====> PowerShell Preview Integrated Console v2021.10.3 <=====

Running profile C:\Users\lit\Documents\PowerShell\profile.ps1
PROFILE is NULL
PS C:\Users\lit>

当TERMINAL命令提示符可用时，PROFILE变量现在包含以下内容。

PS C:\Users\lit> $PROFILE | Format-List -Property *

AllUsersAllHosts       : C:\Program Files\PowerShell\7\profile.ps1
AllUsersCurrentHost    : C:\Program Files\PowerShell\7\Microsoft.VSCode_profile.ps1
CurrentUserAllHosts    : C:\Users\lit\Documents\PowerShell\profile.ps1
CurrentUserCurrentHost : C:\Users\lit\Documents\PowerShell\Microsoft.VSCode_profile.ps1

这些是概要文件脚本。请注意，这两个Microsoft.VSCode_profile.ps1文件都不存在。
