Good Evening guys,
i am having issue installing ErpNext on my Local ubuntu 16.04.
below is my error. any help please
Can't rollback cryptography, nothing uninstalled.
Command "/usr/bin/python3 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-q8lonrrg/cryptography/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-hnxc2rng-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-q8lonrrg/cryptography/
You are using pip version 8.1.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Awaits response
As Error message suggests, you are using older version of pip. upgrading it will help you install all required packages easily.
Assuming you are using frappe as user
su - frappe
cd ~/frappe-bench/
./env/bin/pip install --upgrade pip
If you are installing ERPNext v12, then it is recommended you use virtual environment + python 3.6+
This is error i get updating the pip
Defaulting to user installation because normal site-packages is not writeable
Requirement already up-to-date: pip in ./.local/lib/python2.7/site-packages (20.0.2)
i have not even installed ErpNext yet
the command that led to that error is
python install.py --production --user frappe
Your local python version due to misconfiguration may lead to even more errors, try isolating your environments to not break your OS python modules and dependencies.
Search for how to install python version 3+ without removing your existing python on your machine once installed try following:
python3 install.py --production --version 12 --python python3 --user frappe
Note: if it is broken during install. You may safely delete frappe user and its home directory if you want to clean start.
If you are familiar with docker then now you have option to deploy erpnext and its components using docker. it is far more clean, easier to deploy approach is above one does not work for you.
