These instructions are written for Python 3.5+. If you need help installing or upgrading Python, please visit the Hitchhiker's Guide to Python.
Check which version of Python you have installed by running this command:
$ python -V
If you have Python 2 installed, you may also have a separate installation of Python 3. Check with this command:
$ python3 -V
For best results, you should use a clean virtual environment. This will help avoid potential problems later.
Start a new virtual environment using these commands:
$ python3 -m venv ~/.virtualenvs/venv$ source ~/.virtualenvs/venv/bin/activate
Use pip to install Ethdata in your virtual environment.
(venv) $ pip install eth-data-tools
From time to time, you may want to upgrade to the latest version.
(venv) $ pip install eth-data-tools --upgrade
