Set-StrictMode是否与参数块不兼容？

Question

我有一个简单的脚本

Param([string] $myStringValue)
echo $myStringValue

当我打电话给它时./test.ps1 -myStringValue steve,它运作得很好.

但是如果我在开头添加Set-StrictMode:

Set-StrictMode -Version Latest
Param([string] $myStringValue)
echo $myStringValue

我收到以下错误:

> ./test.ps1 -myStringValue steve
The variable '$myStringValue' cannot be retrieved because it has not been set.
At D:\code\cadgraphics\test.ps1:2 char:20
+     Param([string] $myStringValue)
+                    ~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (myStringValue:String) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined

The variable '$myStringValue' cannot be retrieved because it has not been set.
At D:\code\cadgraphics\test.ps1:3 char:10
+     echo $myStringValue
+          ~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (myStringValue:String) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined

我$myStringValue事先尝试过设置

$myStringValue = ''
Set-StrictMode -Version Latest
Param([string] $myStringValue)
echo $myStringValue

但这只是让它在Param块上窒息:

Param : The term 'Param' 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.
At D:\code\cadgraphics\test.ps1:3 char:5
+     Param([string] $myStringValue)
+     ~~~~~
    + CategoryInfo          : ObjectNotFound: (Param:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

我究竟做错了什么？

我认为问题在于param()需要首先(或者仅在某些特殊陈述之前).放在块Set-StrictMode后面param().

您可以在ISE中看到这一点,因为语法突出显示param()将从深蓝色(语句)更改为蓝色(cmdlet/function/expression).
