See Digital Ocean's quick guide to setting up a local Python programming environment, including virtual environments, which is what I did for SoundScrape Btw, SoundScrape is a neat tool to download sound files from SoundCloud. [1]

Python Packaging[edit | edit source]
In the old days (2015) there were still debates about how to package Python and install stuff. Now, it's settled. Use pip. Easy_install is dead. See the docs. Also note that venv is the successor to virtualenv
Basic PIP[edit | edit source]
Do NOT (normally) use sudo with pip. Use a virtual environment:
$ virtualenv myenv
.. some output ..
$ source myenv/bin/activate
(myenv) $ pip install what-i-want
You only use sudo or elevated permissions when you want to install stuff for the global, system-wide Python installation.
It is best to use a virtual environment which isolates packages for you. That way you can play around without polluting the global python install.
As a bonus, virtualenv does not need elevated permissions.
- Installing a package is as simple as
pip install foo - Upgrades are
pip install --upgrade foo pip uninstall fooif you want to remove foo
References[edit source]
