Sublime怎么更改Powershell为CMD

if os.name == 'nt':             # if os.path.exists(os.environ['SYSTEMROOT'] +             #         'System32windowsPowerShellv1.0powershell.exe'):             #     # This mimics the default powershell colors since calling             #     # subprocess.POpen() ends up acting like launching powershell             #     # from cmd.exe. Normally the size and color are inherited             #     # from cmd.exe, but this creates a custom mapping, and then             #     # the LaunchPowerShell.bat file adjusts some other settings.             #     key_string = 'Console%SystemRoot%_system32_' +              #         'WindowsPowerShell_v1.0_powershell.exe'             #     try:             #         key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER,             #             key_string)             #     except (WindowsError):             #         key = _winreg.CreateKey(_winreg.HKEY_CURRENT_USER,             #             key_string)             #         _winreg.SetValueEx(key, 'ColorTable05', 0,             #             _winreg.REG_DWORD, 5645313)             #         _winreg.SetValueEx(key, 'ColorTable06', 0,             #             _winreg.REG_DWORD, 15789550)             #     default = os.path.join(package_dir, 'PS.bat')             #     sublime_terminal_path = os.path.join(sublime.packages_path(), installed_dir)             #     # This should turn the path into an 8.3-style path, getting around unicode             #     # issues and spaces             #     buf = create_unicode_buffer(512)             #     if windll.kernel32.GetShortPathNameW(sublime_terminal_path, buf, len(buf)):             #         sublime_terminal_path = buf.value             #     os.putenv('sublime_terminal_path', sublime_terminal_path.replace(' ', '` '))             # else :             default = os.environ['SYSTEMROOT'] + 'System32cmd.exe'          elif sys.platform == 'darwin':
