Set/change the global(default) Python version in your computer.

Pyenv is a tool used to manage different Python versions. As mentioned, there are many tools to do this, and I will talk about the ones I find easy to understand and use. You will be able to install, uninstall, update, etc in one virtual environment, without affecting the rest of them. Many combinations of compatibility issues can be found but by having those isolated environments you can avoid them. As well as this, a determined version of a package can generate conflicts with packages or Python versions. Also, you may need a determined version of a package in one project and another version for others. ItвЂ™s common for certain package versions to be supported only by determined Python versions. In the following image, you can see an abstract example of different Python projects containing the different combinations of packages that you can install:Д®ach big colored box represents a Python virtual environment. There are many ways to do this and I will highlight two tools to do so: PyenvВ and Pipenv. However, this can generate a lot of compatibility issues unless you manage them correctly using virtual environments.

If working locally on several Python projects, developers may need to use different Python versions on each.Д«y doing this, they will be able to install different packages and have different versions of the named packages for each environment.

Open a new terminal session and youвЂ™ll see that itвЂ™s still 3.10.0 Additional Python versionsДЇor this session we actually want Python 3.9.6, to accomplish this install 3.9.6 like so: pyenv install 3.9.A Python virtual environment is an important tool for developers when separating project dependencies in isolated environments.

Great! Now how do we set that as the вЂњglobalвЂќ default? ~ pyenv global 3.10.0

No, not yet, we still need to enable it, do so for this session by running: ~ pyenv local 3.10.0 OK, letвЂ™s check it out did it work? python -version ~ python -version Then install Python 3.10 pyenv install 3.10.0 I have Xcode installed, if you donвЂ™t then you may need to follow these steps first xcode-select -install LetвЂ™s install Python 3.10 and set it as the local version of Python to use for this terminal session. We now have pyenv correctly installed and ready for application. Now we have to reload our terminal source ~/.zshrc Now I am use zsh if you are using bash that should read: cat > ~/.bash_profile If command -v pyenv 1>/dev/null 2>&1 then

Next we update and install pyenv brew updateД®xport PATH=' $PYENV_ROOT /shims: $PATH ' You can install HomeBrew in a terminal like so: /bin/bash -c ' $(curl -fsSL ) '

To accomplish this we first start with Homebrew, If your reading this your likely familiar, if not Homebrew is a software manager that is priamrliy used for MacOs ( though I do use it on linux ) to install the software I require with ease. I really want Python 3.10 for Pygame, and 3.9 for AWS Lambda, this is how you can accomplish that.

In this example I am setting up my 2020 M1 MacBook pro, by default the Python version is: ~ python -version Pyenv allows me to install and manage as many version as python as I need and flip between them where required, it uses a convention to allow my terminal to use a version on Python installed under my home directory rather then over writing the global install. I do not want to edit symlinks to the python binaries.I do not want to override the default version of Python on the Mac in-case itвЂ™s required some something else.I want to use multiple versions of Python locally.I use Python more and more regularly and each time I set up a new machine I go through the same steps, I forget a step and am left scratching my head, this time I decided to document them.
