You can use the _winregmodule on windows: First find out the path in the registry (eg starting regedit.exeand using its find function). Then you can query this path as I did it once to find the home directory of R:
您可以_winreg在 windows 上使用该模块：首先在注册表中找出路径（例如启动regedit.exe并使用其查找功能）。然后你可以查询这个路径，就像我曾经做过的那样找到R的主目录：
key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, "Software\R-core\R")
value = _winreg.QueryValueEx(key, "InstallPath")[0]
