Environment variables missing when executing via pkexec

Question

If I execute print os.environ without pkexec I get lots of useful system environment variables, however, once I execute with, most of them are gone. How can I get them back with using pkexec? I understand there's a workaround using sudo but haven't found one yet for pkexec

总之，你不能。来自pkexec man page：

  

将运行PROGRAM的环境设置为最小的已知和安全环境，以避免通过LD_LIBRARY_PATH或类似机制注入代码。此外，PKEXEC_UID环境变量设置为调用pkexec的进程的用户标识。

您可以pkexec使用$DISPLAY注释保留一些环境变量（即允许X11程序通过保留$XAUTHORITY和org.freedesktop.policykit.exec.allow_gui来工作）。但是，保留所有环境变量似乎是故意拒绝的决定。
