In the upcoming article, we will discuss How to manage multiple versions of python in different virtual environments and How to manage multiple versions of python Simultaneously. In this article, we have discussed How to Manage multiple Python Versions with Pyenv. We will discuss more features of pyenv in our upcoming article. Like, managing multiple versions of python in a different virtual environment and Managing multiple versions of python Simultaneously. Similarly, pyenv can do much more things apart from basic version management. See the installed location of the python: $ pyenv which python.Deactivate the virtual environment: $ pyenv deactivate.Activate your Virtual environment: $ pyenv activate env_name.Create Virtualenv out of a specific version of python: $ pyenv virtualenv 3.7.2 env_name.Set Python shell specific: $ pyenv shell 3.7.2.Set back System Python version: $ pyenv global system.Set python version locally: $ pyenv local 3.7.2.So the asterisk pointed is the default version of the python which is install and set default by pyenv globally. System (set by /home/vagrant/.pyenv/version) $ python -VĪnd the same can be seen on the pyenv listing. Now go ahead and check the python version like we normally do with python command and you will see the default version changed. Now if you want to keep the python version 3.7.2 as the system default, you can simply use the following commands. * system (set by /home/vagrant/.pyenv/version) To see the list of installed python versions, use the following command $ pyenv versions Once you install and keep the needed list of python on your pyenv list, you can chose and set the default version of the python using pyenv commands.

Before that, you can see all the available versions of python by running the following command $ pyenv install -list So, you can use the install command and following that the version number to install the python. Just like any other package manager, using pyenv, you can install a specific version of python and manage the versions in your operation system. Then, restart the terminal session to make it effective. Then, don’t forget to add the following lines in to the. Once you installed all the dependencies as mentioned in the above section, you can go and straightaway runs the following command to install the pyenv. openSUSE: use zipper: zypper install gcc automake bzip2 libbz2-devel xz xz-devel openssl-devel ncurses-devel readline-devel zlib-devel tk-devel libffi-devel sqlite3-devel.CentOS: use yum – yum install gcc zlib-devel bzip2 bzip2-devel readline-devel sqlite sqlite-devel openssl-devel tk-devel libffi-devel.Debian: use Apt-get – sudo apt-get update sudo apt-get install -no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev.MacOS : use brew – brew install openssl readline sqlite3 xz zlib. ![]()
