在路径变量中的 PowerShell 中执行一个 exe 文件

Question

我在已添加到我的路径变量的文件夹中有一个 exe 文件 fciv.exe。 我使用

检查了它

$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。

相同的命令在 cmd 命令提示符下有效。

我将执行策略设置为无限制 我还应该做些什么来让它在 Powershell 中工作吗？

注意"E:\My Software\FCIV"为fciv可执行文件所在目录

查看命令跟踪并发现它在正确的文件夹中寻找 fciv.EXE 但直接跳过，我认为扩展名 .EXE 的大写是问题所以我尝试将 .exe 添加到PATHEXT 变量

现在它在正确的文件夹中寻找 fciv.exe，但仍然直接跳过它并说它已经用尽了当前目录中的当前模式。

我想通了，好像在我的PATH环境变量

"E:\My Software\FCIV"

出现在双引号内，而其他目录则没有。 尽管如此，命令提示符 cmd 仍能正常工作，但 powershell 却不行， 我不明白为什么，但我很高兴我至少找到了解决问题的方法。

_{注意：您已经用答案更新了问题，但很高兴发布实际答案。}

在您的调试跟踪中，您得到如下行：

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

路径是 "E:\My Software\FCIV" 而它应该是 E:\My Software\FCIV。
这表明您的路径设置不正确，并且在不需要时在您的路径中引用了此项。

这是我当时的一个示例跟踪的摘录 运行 iexplore.exe:

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，路径未被引用，它找到了可执行文件。
