I can't ping between 2 Nexus 9k's. Both interfaces are configured as follows:
Nexus Switch 1:
int eth1/18
ip address 192.168.1.1/31
no shut
Nexus Switch 2:
int eth1/18
ip address 192.168.1.2/31
no sh
I also tried configuring an 'ip route' on either switch to each other. It's still saying 'no route to host'....Do I need a routing protocol put on the interface since it a 'routed' port? Thanks for your help!

Hello!
In a way, the Nexus is telling you the truth here - 192.168.1.1/31 and 192.168.1.2/31 are in different subnets. Since you are using /31 subnets, the two IP addresses in the first subnet are 192.168.1.0 and 192.168.1.1, while the two IP addresses in the second subnet are 192.168.1.2 and 192.168.1.3. Therefore, 192.168.1.1/31 and 192.168.1.2/31 are in two different subnets.
To fix this, you have the following options:
I hope this helps - thank you!

I cannot post full configuration, its a secure network.
Version: nxos 9.3.7
However, here is the features:

The interfaces are:
Nexus Switch 1:
int eth1/18
ip address 192.168.1.1/31
no shut
Nexus Switch 2:
int eth1/18
ip address 192.168.1.2/31
