PowerShell New-Item 将创建脚本所在的目录，而不是指定的路径

Question

我正在编写一个 PowerShell 脚本，我需要在 C:\Users

中创建一个目录

我的脚本位于桌面上。

我创建目录的脚本行是这样的：

New-Item -ItemType "directory" -Force -Path "C:Users\username\scripts\documents"

而是创建目录：

C:\Users\username\Desktop\Users\username\scripts\documents

如何直接在C:\Users中新建目录？

Answer 1

路径根（驱动器盘符）后缺少反斜杠 \：

New-Item -ItemType "directory" -Force -Path "C:\Users\username\scripts\documents"

另请参阅：https://docs.microsoft.com/en-us/dotnet/api/system.io.path.ispathrooted?view=net-5.0

A rooted path is file path that is fixed to a specific drive or UNC path; it contrasts with a path that is relative to the current drive or working directory. For example, on Windows systems, a rooted path begins with a backslash (for example, \Documents) or a drive letter and colon (for example, C:Documents).

Note that rooted paths can be either absolute (that is, fully qualified) or relative. An absolute rooted path is a fully qualified path from the root of a drive to a specific directory. A relative rooted path specifies a drive, but its fully qualified path is resolved against the current directory. The following example illustrates the difference.

$relative1 = "C:Documents"
$relative2 = "\Documents"
$absolute = "C:\Documents"

foreach ($p in $relative1,$relative2,$absolute) {
    "'$p' is Rooted: {0}" -f [System.IO.Path]::IsPathRooted($p)
    "Full path of '$p' is: {0}" -f [System.IO.Path]::GetFullPath($p)
}

（我没有在链接示例中包含 [System.IO.Path]::IsPathFullyQualified() 调用，因为它不包含在 Windows PowerShell 5.1 中）
