Jitsi-Meet : node.js path error

Hi,
I am getting below mentioned error although, I have installed node.js and specified the
path which is mentioned in the error.

Error : path /jitsi-meet-master\node_modules\react-native-background-timer\package.json (The system cannot find the path specified)

What are you trying to do or what commands are you trying to run? Have you done an npm install to download jitsi-meet dependencies?
