我无法正确安装 Graphene ( https://graphene.readthedocs.io/en/latest/building.html )。运行示例代码时，我收到以下错误

Cannot open device /dev/gsgx. Please make sure the Graphene SGX kernel module is loaded.

这可能是因为，在安装命令期间 sudo insmod gsgx.ko，我收到以下错误

insmod: ERROR: could not insert module gsgx.ko: Required key not available.

其余所有（与 SGX 相关）似乎很好，因为我能够运行示例 SGX 示例并sudo service aesmd status给出

您是否尝试过单独安装 /dev/gsgx（如2b步骤中所述）？我在尝试运行一些 GSC 示例时遇到了同样的错误，但遵循 2b 应该可以工作，即使它不是用于生产。
