Issue in installing ujson in ubuntu

Question

I am trying to install ujson which is required dependency for the installation of RASA. The command I triggered is follows:

sudo pip3 install ujson

And got the following error message.

WARNING: The directory '/home/kamaldeep/.cache/pip' or its parent directory is not owned or is not writable by the current user. The cache has been disabled. Check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.
