无法运行带有脚本中引用参数的程序,但可以直接从命令行运行它

无法运行带有脚本中引用参数的程序,但可以直接从命令行运行它

我有这个脚本(在我的个人资料中别名为ydl):

param(
    [string]$url,
    [switch]$vid=$false
)

$ydl = "D:\youtube-dl\youtube-dl.exe"

$mp3conf = "--config-location `"D:/youtube-dl/config-mp3.txt`""
$vidconf = "--config-location `"D:/youtube-dl/config-mp4.txt`""

$finalArgs = $mp3conf

If ($vid) {
    $finalArgs = $vidconf
}

Write-Host $ydl $url $finalArgs
& $ydl $url $finalArgs

Powershell 输出:

PS D:\> ydl https://www.youtube.com/watch?v=c_7Mcb6iLN0
D:\youtube-dl\youtube-dl.exe https://www.youtube.com/watch?v=123 --config-location "D:/youtube-dl/config-mp3.txt"
Usage: youtube-dl.exe [OPTIONS] URL [URL...]

youtube-dl.exe: error: no such option: --config-location D:/youtube-dl/config-mp3.txt

好吧?真不幸……但如果我尝试直接运行该命令——Write-Host从脚本的输出中复制它,会怎么样?

Powershell 说参数列表的结果如下:
D:\youtube-dl\youtube-dl.exe https://www.youtube.com/watch?v=123 --config-location "D:/youtube-dl/config-mp3.txt"

好的,我们来尝试一下:

PS D:\> D:\youtube-dl\youtube-dl.exe https://www.youtube.com/watch?v=123 --config-location "D:/youtube-dl/config-mp3.txt"
[youtube] 123: Downloading webpage
[youtube] 123: Downloading video info webpage
[youtube] 123: Extracting video information

[ffmpeg] Destination: D:\youtube-dl\MP3\123.mp3
Deleting original file D:\youtube-dl\MP3\123.webm (pass -k to keep)

怎么回事?它在命令行中可以工作,但在脚本中却不行?
