不可天，
在遵循@Trevor Sullivan发布的回复this question的教程时，我无法让脚本运行。它失败了，因为它无法找到日志文件。起初我以为它可能是一个权限问题，所以我明确指定了日志文件的文件路径，我仍然收到相同的错误消息。
如何修复代码以使其运行？
这里的代码：
function Copy-WithProgress {
[CmdletBinding()]

[Parameter(Mandatory = $true)]
[string] $Source
, [Parameter(Mandatory = $true)]
[string] $Destination
, [int] $Gap = 0
, [int] $ReportGap = 2000
)

# NC = Don't log file classes (existing, new file, etc.)
# BYTES = Show file sizes in bytes

看着你的代码，它几乎就像有人用反斜杠逃脱了它。将所有\\替换为\，并将\'替换为'。看看这是否无法解决您的问题。

隔离Get-Content行并使用文字路径进行测试。如果仍然失败，请尝试添加-Force开关。
