问题

我正在尝试实现一个GitHub操作，用于编译`.mq4`文件。目前，我有一个PowerShell脚本，根据[这里][1]描述的格式执行此操作：

```powershell
$url = "http://www.rosasurfer.com/.mt4/{0}/metaeditor.exe" -f $Version
$exePath = "metaeditor.exe"
if ($verbose) {
    Write-Host "Attempting download from $($url)..."
}

try {
    Invoke-WebRequest -Uri $url -OutFile $exePath
} catch {
    Write-Error "Failed to download MetaEditor from $($url), error: $($_.Exception.Message)"
}

Out-File -FilePath $LogFile

$args = New-Object System.Collections.Generic.List[string]
$args.Add("/portable")
$args.Add('/compile:"{0}"' -f (Resolve-Path $Files))
$args.Add('/inc:"{0}"' -f (Resolve-Path $Includes))
$args.Add('/log:"{0}"' -f (Resolve-Path $LogFile))
if ([System.Convert]::ToBoolean($SyntaxOnly)) {
    $args.Add("/s")
}

$exePath = Resolve-Path $exePath
try {
    Start-Process $exePath -ArgumentList $args
} catch {
    Write-Error "Compilation failed, error: $($_.Excaption.Message)"
}

gc $LogFile

我遇到的问题是，这个脚本没有失败，但也没有生成.ex4文件。日志文件也是空的。我尝试使用完全限定的路径到metaeditor实例，输入文件，包含目录和日志文件，正如这里建议的那样，但我仍然什么都得不到。

I&#39;m trying to implement a GitHub action that compiles `.mq4` files. Currently, I&#39;ve got a Powershell script that does that, according to the format described [here][1]:

$url = "http://www.rosasurfer.com/.mt4/{0}/metaeditor.exe" -f $Version
$exePath = "metaeditor.exe"
if ($verbose) {
Write-Host "Attempting download from $($url)..."
}

try {
Invoke-WebRequest -Uri $url -OutFile $exePath
} catch {
Write-Error "Failed to download MetaEditor from $($url), error: $($_.Exception.Message)"
}

Out-File -FilePath $LogFile

$args = New-Object System.Collections.Generic.List[string]
$args.Add("/portable")
$args.Add('/compile:"{0}"' -f (Resolve-Path $Files))
$args.Add('/inc:"{0}"' -f (Resolve-Path $Includes))
$args.Add('/log:"{0}"' -f (Resolve-Path $LogFile))
if ([System.Convert]::ToBoolean($SyntaxOnly)) {
$args.Add("/s")
}

$exePath = Resolve-Path $exePath
try {
Start-Process $exePath -ArgumentList $args
} catch {
Write-Error "Compilation failed, error: $($_.Excaption.Message)"
}

gc $LogFile

The issue I'm having is that this script doesn't fail, but doesn't produce an `.ex4` files either. The log file is also empty. I tried using fully-qualified paths to the instance of `metaeditor`, the input files, include directory and log file as was suggested [here][2], but I'm still not getting anything.

So, it turns out this was an artifact of the version of MetaEditor I was using. I'm not sure why, but version 4.1370.0 wasn't producing any output. Changing the version to the most recent one, fixed the issue and I can now compile my `.mq4` and `.mqh` files.
