![]() ![]() In the previous section, we saw how to use pyenv in a global setup. The global version is somethow determined by: ~/.pyenv/version We see that which python points to: ~/.pyenv/shims/pythonīecause ~/.pyenv/shims is prepended to PATH with the rc scripts. We can confirm that everything is locally installed in our clean environemnt with: python -c 'import cowsay print(cowsay._file_)' Python -c 'import cowsay cowsay.tux("Python is fun")' We can now proceed to install and use packages normally: pip install cowsay Select a different python version: pyenv global 3.8.0 We now have: * system (set by /home/cirsan01/.pyenv/version) List available Python versions: pyenv versions ![]() # Build and install a Python version from source. Xz-utils tk-dev libffi-dev liblzma-dev python-openssl git Libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \ Sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \ Install the python version you want: # Increase the chances that the build will have all dependencies. bashrc: export PATH="$/.pyenv/bin:$PATH"įind Python version to install: pyenv install -list Pyenv allows you to manage multiple Python versions without sudo for a single user, much like Node.js NVM and Ruby RVM. This method does not use apt-get, but it is, I believe, the best option available today, as it can easily compile any Python version from source for you, so you don't have to rely on any PPAs. Step 4 – Check the Python VersionĬheck the latest version installed of python using below command. Make altinstall is used to prevent replacing the default python binary file /usr/bin/python. Use below set of commands to compile python source code on your system using altinstall. You can also download latest version in place of specified below. Sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-devĭownload Python using following command from python official site. sudo apt-get install build-essential checkinstall Use the following command to install prerequisites for Python before installing it. If you run run brew doctor without the fix, it will show config warnings related to the python configuration files.Ĭonfiguration for ~/.zshrc or ~/.Just follow this steps (tested) : Step 1 – Install Required Packages When using this method it may conflict with brew as it uses python as well. If they aren't and you are using the same zsh or bash config it will ignore loading them Second to Executable Paths we will add two if statements that will check if the pyenv,pyenv-virtualenv are installed, if they are it will load them.If you have any other path that you use, you can add them at the same line or create a new line below this one. In the example we added all the common paths, including the paths for pyenv, pyenv-virtualenv. First of all we need to include your Executable Paths.It's very imported to maintain the order of the configuration for the loading order In order to use pyenv, pyenv-virtualenv without conflicting with the native macOS python we need to add some configuration to our ~/.zshrc config (for mac os catalina) or your bash config if you are still using bash. Installing and configuring pyenv, pyenv-virtualenv ¶ This way all the system related versions of python and their packages won't be affected and use by you. The right way to use python at macOS is to use Virtual Environments for python. When using Python2, Python3 and their package managers this way, all the packages will be installed at the system level and my effect the native packages and their dependences, this can break or lead to unwanted bugs in OS. When Xcode Command Line Tools are installed Python 3 and pip3 package manager will be available at the cli. The reason for that is that macOS uses Python 2 for its core system with pip as a package manager. Using and developing with Python on macOS sometimes may be frustrating.
