无法加载redis模块，RedisJSON

Question

按照here指定的指令编译RedisJson的源代码后，在project_root/target/release得到rejson.so文件，然后我输入这个命令 sudo redis-server --loadmodule /home/username/RedisJSON /target/release/rejson.so 加载 redis 模块。但是我收到了这个错误信息。

To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

请问如何解决这个问题？

RedisJSON 需要 Redis 6+，看来您是在旧版本的 Redis 上运行。
