Question

我在我添加到路径变量的文件夹中有一个exe文件fciv.exe。我用

检查了一下

$env:Path

但是，如果我只是指定命令的名称，

fciv -h

powershell显示命令未找到异常。

相同的命令在cmd命令提示符下有效。

我将执行策略设置为不受限制我还有什么办法让它在Powershell中运作吗？

修改

请注意＆＃34; E：\ My Software \ FCIV＆＃34;是fciv可执行文件所在的目录。

查看命令跟踪，看到它正在寻找fciv.EXE在正确的文件夹中，但跳过右侧，我认为扩展的大写.EXE是问题，所以我尝试添加.exe到PATHEXT变量

现在它在正确的文件夹中查找fciv.exe，但仍然跳过它并说它已经耗尽当前目录中的当前模式。

我已经弄清楚了，似乎在我的 PATH 环境变量中

"E:\My Software\FCIV"

出现在双引号内，而没有其他目录。命令提示符 cmd 能够工作尽管如此，但PowerShell不是，我不知道为什么，但我很高兴我至少知道如何解决问题。

_{注意：您已经用答案更新了您的问题，但发布实际答案真的很棒。}

在调试跟踪中，您将获得如下所示的行：

DEBUG：CommandDiscovery信息：0：在＆＃34; E：\ My Software \ FCIV＆＃34;
中寻找fciv.ps1

路径为"E:\My Software\FCIV"，应为E:\My Software\FCIV 这表示您的路径设置不正确，并且当您不需要时，会在您的路径中引用此项目。

以下是我运行iexplore.exe的示例跟踪的摘录：

DEBUG：CommandDiscovery信息：0：寻找iexplore.exe。* in   C：\ Program Files（x86）\ Internet Explorer
DEBUG：CommandSearch   信息：0：WriteLine找到下一个路径：C：\ Program Files   （x86）\ Internet Explorer \ iexplore.exe
调试：CommandDiscovery   信息：0：找到命令：路径（C：\ Program Files（x86）\ Internet   Explorer \ iexplore.exe）是一个名称为：iexplore.exe
的应用程序

请注意，路径未引用，并且找到了可执行文件。
