powershell - 找不到已安装的脚本作为可执行文件

Question

有一个名为 Get-Stuff.ps1 的脚本以 PSScriptInfo 为首堵塞。该脚本将发布到 NuGet 存储库。然后将其安装到预期位置 C:\Users\lit\Documents\WindowsPowerShell\Scripts\Get-Stuff.ps1 . Get-InstalledScript报告它已安装。但是，它不是一个可执行文件。 C:\Users\lit\Documents\WindowsPowerShell\Scripts\目录不在 $Env:PSModulePath 中.
安装后我错过了什么步骤才能使该命令可执行？

PS C:\> (Get-ChildItem -Recurse -File -Path 'C:\' -Filter 'Get-Stuff*' -ErrorAction SilentlyContinue).FullName

是$env:PATH这对于仅按文件名调用 *.ps1 很重要文件 (脚本文件)，而不是 $env:PSModulePath ，仅适用于模块。
不幸的是， PowerShellGet module 的早期版本未提供添加 Install-Script 所针对的目录cmdlet 到 $env:PATH坚持，但至少从 v2.2.4 开始，他们会这样做(出现提示)，下次您调用 Install-Script执行实际安装。
尝试更新您的 PowerShellGet带有 Update-Module PowerShellGet 的版本或者，如果失败，Install-Module -Force PowerShellGet (在 Windows PowerShell 中需要提升，除非您指定 -Scope CurrentUser )。

如果你想做这些 $env:PATH添加自己，运行以下代码:
笔记:

修改$env:PATH通过注册表持久化，仅在 Windows 上受支持(在 Unix 上，定义持久性环境变量的机制因平台而异)。

然而，在 Unix 上， session 中的 $env:PATH 也是如此。变量被更新。

& {
  
  Write-Verbose -vb "Adding Install-Script install directories to `$env:PATH..."
  
  $isWin = $env:OS -eq 'Windows_NT'
  $isAdmin = if ($isWin) { [bool] (net session 2>$null) } else { 0 -eq (id -u) }

  $ErrorActionPreference = 'Stop'

  # Determine the locations: current-user, all-user.
  $scriptDirs = (Join-Path (Split-Path ($PROFILE, "$HOME/.local/share/powershell/Modules")[$env:OS -ne 'Windows_NT']) Scripts),
                (Join-Path (Split-Path ("$env:ProgramFiles\$(if ($PSVersionTable.PSEdition -ne 'Core') { 'Windows' })PowerShell\Modules", '/usr/local/share/powershell/Modules')[$env:OS -ne 'Windows_NT']) Scripts)

  if (-not $isWin) {
    # Note: There's no unified mechanism across macOS and Linux.
    Write-Warning "On Unix, this script only supports modifying the *current session*'s `$env:PATH variable."
  } elseif (-not $isAdmin) {
    Write-Warning "Since this session isn't elevated, only the *current-user* location will be added *persistently*."
  }

  $pathVarSep = [IO.Path]::PathSeparator

  $i = 0
  foreach ($dir in $scriptDirs) {
    # Always update the in-session variable.
    Write-Verbose -vb "-- Adding $dir..."
    if ($env:PATH -split $pathVarSep -notcontains $dir) { 
      $env:PATH = ($env:PATH -replace "$pathVarSep`$") + $pathVarSep + $dir 
    } 
    else { 
      Write-Verbose -vb "Already present in-session: $dir" 
    }
    # On Windows, also try to update the *persistent* definitions
    if ($isWin) {
      $scope = ('User', 'Machine')[$i++ -eq 1]
      if ($scope -eq 'Machine' -and -not $isAdmin) { break } # skip due to lack of permissions
      # Note: We query the registry directly, so as to preserve unexpanded REG_EXPAND_SZ values.
      $currVal = Get-ItemPropertyValue ('registry::HKEY_CURRENT_USER\Environment', 'registry::HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment')[$scope -eq 'Machine'] Path
      if ($currVal -split $pathVarSep -notcontains $dir) { 
        [Environment]::SetEnvironmentVariable('Path', (($currVal -replace "$pathVarSep`$") + $pathVarSep + $dir), $scope)
      } else {
        Write-Verbose -vb "Already present persistently in the $scope scope: $dir"
      }
    }
  }

  Write-Verbose -vb 'Done.'
