使用CustomBookNavigationBlock，报错：Call to a member function getCurrentRequest() on null in Drupald8modulePluginBlockCustomBookNavigationBlock->build()

替换CustomBookNavigationBlock如下：

mount -t nfs 192.168.19.133:/volume3/supreme5 /www/wwwroot/data 报错：mount.nfs: access denied by server while mounting 192.168.19.133:/volume3/supreme5

解决办法，群晖上要设置允许要mount机器的ip。
mount -t nfs 192.168.19.133:/volume3/supreme5 /www/wwwroot/data   #注意133是群晖ip。不是nfs配置的ip
