Unable to install mbed on Debain 10

I have followed below steps to install mbed on my Debian Linux Machine by taking this page(https://os.mbed.com/docs/mbed-os/v6.6/build-tools/install-and-set-up.html) as a reference.

After running "pip install mbed-cli" i'm getting below output:

Afther this i run "mbed --version" then it was showing mbed command not found.

Can anyone help me in resolving this issue.

Start by comparing the Python 2.7 installation output and the `mbed --version` failure with the installation and setup page linked in the issue. Check why the installed `mbed` command is not available on Debian 10; done means the command is discoverable and `mbed --version` runs successfully.
