PowerShell 仅在控制台中运行时有效，而不是作为 PS1 可执行文件

Question

我对 PowerShell 相当陌生，并且在尝试使 PS1 可执行文件正常工作时遇到了挑战。在 PowerShell 控制台中运行脚本完全可以正常工作并复制项目并创建正确的日志文件名。

希望右键单击包含脚本的 PS1 文件，使用“使用 PowerShell 运行”运行脚本，然后在用户提示选择是时允许脚本完成填充日志文件并复制文件。

此时，除了 PS1 文件脚本被大量无法识别的符号/字符替换并将日志文件创建为“Box Project Files.ps1JobFileLocations.log”而不是“JobFileLocations.log”之外，没有任何错误消息.

使用的 PowerShell 版本是 5.1。视窗 10 操作系统。对于 CurrentUser 和 LocalMachine，Set-ExecutionPolicy 设置为 Unrestricted 并确认为 Unrestricted。 Unblock-File也试过了。

以下是在 PowerShell 控制台中运行但不能作为 PS1 可执行文件运行的脚本。

有人可以帮我理解将脚本作为 PS1 文件运行有什么问题吗？

您的脚本的问题在于这一行：

$dstRoot = $MyInvocation.MyCommand.Path

$MyInvocation.MyCommand.Path 将根文件系统路径解析为脚本本身 - 这就是您在日志路径中获得Box Project Files.ps1（可能是脚本的名称）的原因。

获取任意文件路径的父目录路径，可以使用Split-Path -Parent：

$dstRoot = Split-Path -LiteralPath $MyInvocation.MyCommand.Path -Parent

话虽如此，从 Windows PowerShell 3.0 开始，目录和脚本文件路径都可以通过 $PSCommandPath 和 $PSScriptRoot 自动变量获得，因此您可以将代码简化为：

$dstRoot = $PSScriptRoot
