PIP is a package manager for Python used for installing and managing additional packages. Once you've switched to a Pyenv version, you can run pip without sudo, and install/upgrade packages easily - without interfering with your system Python: pyenv global 3.7.Python is a general-purpose, high-level programming language used by developers around the world. To check which Python versions are available, run pyenv versions. If you want the “old” system python, run: pyenv global system This switches your python to point to 3.7.4. Now, you can choose your Python version: pyenv global 3.7.4 Choose which Python version you want to use for a given directory, or globallyįor example, to install 3.7, check which versions are available: pyenv install -l | grep 3.7.

That way you don't risk yourself messing around with system-level frameworks (and hence creating a problem removing dependencies etc.). Instead, use a user-level Python distribution installed via pyenv. Here's my number one tip: Do not use sudo with pip. When I try to upgrade pip I'm getting above errors While I was installing it asked me to upgrade pip.
