Disecting the installation command

[muzammil360]

Describe the bug Hi @rbonghi, I wanted to understand disect the command you share for installation

sudo -H pip install -U jetson-stats

From the documentation, it seems that -U will Upgrade all specified packages to the newest. It means that this flag will only make sure you always have the latest packages installed after running it.

However, -H is a bit interesting. sudo documentation says that it will set the HOME directory to current user's directory instead of /root. In this case, will the jetson-stats package be installed in system-wide location /usr/local/lib/python3.6/dist-packages or in ${HOME}/.local/lib/python3.6/site-packages?

In any case, what's the goal of using -H flag?

Hi @muzammil360 ,

I am sorry for my late reply, you have right. I start to use -H in the beginning but now is not necessary. I will check on my board, just to be sure all work and I will remove from all readme.

Thank you!

Picking up an old issue:

Install without -H, I catch always this warning:

WARNING: The directory '/home/nvidia/.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 should use sudo's -H flag.

I need to investigate

I remove this option from next release
