powershell - 在PowerShell中的路径变量中执行exe文件

Question

我在添加到我的路径变量的文件夹中有一个exe文件fciv.exe。
我用

$env:Path

但是，如果我只指定命令的名称，

fciv -h

powershell显示命令未找到异常。

该命令在cmd命令提示符下起作用。

我已将执行策略设置为无限制
为了使它在Powershell中工作，我还有什么需要做的吗？

请注意，“E:\ My Software \ FCIV”是fciv可执行文件所在的目录。

查看命令跟踪并发现它在正确的文件夹中寻找fciv.EXE，但跳过正确的地方，我认为扩展.EXE的大写是问题所在，因此我尝试将.exe添加到PATHEXT变量中

现在，它在正确的文件夹中查找fciv.exe，但仍会跳过它，并说它已用尽当前目录中的当前模式。

我已经弄清楚了，看来在我的 PATH 环境变量中

"E:\My Software\FCIV"

出现在双引号中，没有其他目录。
尽管有此功能，但命令提示符 cmd 仍然可以工作，
我不明白为什么，但我很高兴至少找到了解决问题的方法。

注意:您已经用答案更新了您的问题，但是发布实际答案很好。

在调试跟踪中，您将获得如下所示的代码行:

DEBUG: CommandDiscovery Information: 0 : Looking for fciv.ps1 in "E:\My Software\FCIV"

路径应为"E:\My Software\FCIV"，但应为E:\My Software\FCIV。
这表明您的路径设置不正确，并且在不需要时将其引用在您的路径中。

这是我运行iexplore.exe之后的示例跟踪的摘录:

DEBUG: CommandDiscovery Information: 0 : Looking for iexplore.exe.* in C:\Program Files (x86)\Internet Explorer
DEBUG: CommandSearch Information: 0 : WriteLine Next path found: C:\Program Files (x86)\Internet Explorer\iexplore.exe
DEBUG: CommandDiscovery Information: 0 : Command Found: path (C:\Program Files (x86)\Internet Explorer\iexplore.exe) is an application with name: iexplore.exe

请注意，没有引用路径，而是找到了可执行文件。
