“启动python”在Windows的MS Powershell中不起作用

Question

Until yesterday I used to be perfectly able to run python scripts in python like so -

start python [python_script_name]

However by now, (in this span of time, I have installed GitHub, gotten stuck in booting Windows 7 and forced to use Windows Restore which removed GitHub and now Windows 7 boots) I can only use

start python.exe [python_script_name]

Can anyone tell me what's going on here?

[Python version - 2.7.5 Windows 7 Home]

start is a command built into cmd.exe , not PowerShell.exe. In PowerShell, start is a default alias for the Start-Process cmdlet, which operates differently than the start command in cmd.exe.

In PowerShell, you'll want to use a command like:

Start-Process -FilePath c:\path\to\python.exe -ArgumentList 'c:\path\to\script.ps1' -Wait -NoNewWindow;
