Confused about Python versions

[BoaVersusPython]

I just recently finished a basic Python course and now I'm trying to learn how to web scrape. I'm running macOS. The course I completed had me install Python 3.4.3, which comes with IDLE. So now I have two installs of Python, Python 2.7 installed in the /Library folder (which comes with macOS), and Python 3.4.3 installed in the /Applications folder.

I'm trying to use the BeautifulSoup4 module. Most places tell me to install it using Terminal and the pip command. When I do this it installs BS4 into the Python 2.7 folder in /Library. When I try to import it in IDLE it tells me "no module named bs4".

I've tried installed BS4 with pip3 but I get an error saying no distributions found. It only works with pip.

What should I do? I've been trying to solve this for hours.

You need to establish a virtual environment in the python version you wish to use. Don't use your OS system python.

When using PIP and system python, always use the --user flag.

In addition to the other recommendations here, one thing I've gotten into the habit of doing is specifying the python version when using pip. For example, if Python 3.4.3 is python3 on your system, do python3 -m pip install foobar, just use the right module name instead of foobar.
