Jitsi make failed

Hi,

I am very new to jitsi. I want to make some changes to the web-UI. I clone jitsi to my Debian 10 server and run the commands as mentioned in Developer Guide (Web). Node v12.17.0 and npm 6.14.4. First I clone and run npm install. Finally, I ran

make

and I am getting this error.

I was able to fix this issue by adding more heap and increasing the file watch limit.

Was you installation based on windows or Linux operating system?
