# Reporters - Javier Mateos (NAUDIT) - Rafael Leira (NAUDIT) - Lluis Gifre (CTTC) # Description There is an incompatibility issue when preparing development environment for TeraFlowSDN; in particular, components E2E Orch, VNTM, and NBI use `websockets==12.0` while Device uses `websockets==10.4`. Upgrading to version 12.0 as features used in Device are compatible with that version also. ## Deployment environment - Operating System (include version): any - MicroK8s (include version and add-ons): any - TeraFlowSDN (include release/branch-name/commit-id): develop ## TFS deployment settings Preparation of development environment. ## Sequence of actions that resulted in the bug Preparation of development environment. ## Document the explicit error Run: ```bash $ ./install_requirements.sh ``` Output log: ``` Creating integrated requirements file... Collecting requirements from components... Compiling requirements... ERROR: Cannot install websockets==10.4 and websockets==12.0 because these package versions have conflicting dependencies.
