@azizullah2017 This looks like a permissions problem similar to https://github.com/npm/npm/issues/7407. It was recommended in that issue to take ownership of your .npm directory with

$ sudo chown -R $(whoami) $HOME/.npm

and try installing again with

$ sudo npm install mrbot-ai/rasa-webchat

Hi @azizullah2017, the permissions error is still coming from your .npm directory. This is a common issue with npm, with the solution here.

It looks like even though you are installing locally, the git repo is being cloned to the tmp directory in your global .npm directory (/home/user/.npm/_cacache/tmp) which has restricted permissions. If you follow the steps in the link it should fix the issue. I hope this helps.

Edit: If you follow the steps it should no longer be necessary to run the command with sudo
