使用绝对路径包含空格执行Powershell文件

Question

I'm trying to execute a ps1 file in my python script.

proc = subprocess.Popen(["powershell.exe", 'F:/FOLDER/FOLDER OK/myfile.ps1'])

It stopped at F:/FOLDER/FOLDER so I added additional quotes like this:

proc = subprocess.Popen(["powershell.exe", '"F:/FOLDER/FOLDER OK/myfile.ps1"'])

No error now, but it didn't execute the script either... Any idea?

Answer 1

powershell.exe does not assume that a parameter is automatically a file to execute; you need to identify all parameters. Use the -File switch

proc = subprocess.Popen(["powershell.exe", "-File", r"F:\FOLDER\FOLDER OK\myfile.ps1"])

^{The r in r"..." (for raw ) turns off escape-sequence processing so that \\ can be used without escaping.}

See PowerShell Command Line Help at Microsoft Docs.
