@SANTOSH-KUMAR Did you run npm install in the Nodebb folder?

[SANTO007]

yeah installed
is this the code
npm install
or
sudo apt-get npm install

[a_5mith]

@SANTOSH-KUMAR Just npm install

Does this command install redis db
sudo apt-get install git nodejs redis-server build-essential imagemagick

@SANTOSH-KUMAR Your redis is out of date. Needs to be greater than v2.4
