Easy install script installs bench only in editable mode!?

Hello,

I have installed ERPNext using the easy install script as below. This is what the official easy installation instructions say.

$ wget https://raw.githubusercontent.com/frappe/bench/develop/install.py
$ python3 install.py --production

However the bench gives the following message saying it is in editable mode. Can someone please tell me how to correct this?

WARN: bench is installed in editable mode!

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: `pip install frappe-bench`

I have tried to uninstall and reinstall bench again but no command worked! Including
sudo pip uninstall bench which gives Skipping bench as it is not installed.
