Question

脚本在Powers shell ISE中给我回复，但收到错误消息，表明HelpList未被识别为cmdlet的名称' 下面是脚本。

param($param1 = '')
if($param1 -eq '' )
{
    HelpList
}
function HelpList() 
{ 
   Write-Host "DevelopmentBuild.ps1 help"
}
function clean()
{
    Write-Host "Cleaning solution"
}

从Powershell控制台运行时，下面是错误。

PS C:\WorkSpace\Dev> .\deploymentScript.ps1
HelpList : The term 'HelpList' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At C:\WorkSpace\Dev\deploymentScript.ps1:17 char:13

Answer 1

PowerShell的范围规则基于所谓的＆＃34;词汇范围＆＃34;。必须在使用之前定义或导入任何未内置的变量或函数。在上面的脚本中，您没有在调用它时定义HelpList。重新排列代码：

param($param1 = '')

function HelpList() 
{ 
   Write-Host "DevelopmentBuild.ps1 help"
}

function clean()
{
    Write-Host "Cleaning solution"
}

if($param1 -eq '' )
{
    HelpList
}

这样，当脚本到达您调用它的点时，将定义HelpList，并且不会抛出undefined-cmdlet错误。

Answer 2

尝试在代码之前定义函数：

function HelpList() 
{ 
    Write-Host "DevelopmentBuild.ps1 help"
}
function clean()
{
    Write-Host "Cleaning solution"
}

param($param1 = '')
if($param1 -eq '' )
{
    HelpList
}

脚本在Powershell ISE中工作但不在PowerShell控制台中？
