This will create a virtual environment for you with the following files in the virtual environment directory my_env: We can run the following command to create a virtual environment: python3 -m venv my_env Each virtual environment has its own Python binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Python packages in its site directories. The venv module provides support for creating lightweight “virtual environments” with their own site directories, optionally isolated from system site directories. Use venv to create Virtual EnvironmentĪs per the official documentation of venv module, To verify the successful installation of Python 3.x version, run the python3 command and the IDLE should start in your terminal.
#REMOVE PYTHON ON MAC INSTALL#
Homebrew will also install pip for you which you can verify by running the pip3 command. Once you have Homebrew set up, run the following command to install the latest version of Python: $ brew install python If you don't have Homebrew installed on your Macbook, you can install Homebrew on your MacOSX and then use it to install Python 3.8 on your machine. We will use Homebrew to install Python 3.8 and will then move on to creating a virtual environment.
So to set up a virtual environment, we won't be using virtualenv or virtualenvwrapper module, which are most popular to set up a virtual environment.īut we will be using the venv module which comes as a default with Python 3.x version and is recommended to use for virtual environment creation.
You can set up a different virtual environment for each project for example if you are working on one project based on Tkinter module, some other projects based on Numpy module, then you can easily do this. We can have different versions of Python installed inside the virtual environment. When we have a virtual environment, then we can install new packages inside the virtual environment which will not affect the operating system's python modules. You must be thinking about why we need a virtual environment? So here are a few points in its favor: Instead, you should set up a virtual environment for your development purpose.
#REMOVE PYTHON ON MAC UPDATE#
If you are a Mac user, you should know that Python 2.7.x comes pre-installed in your Macbook, but as that is required by your operating system, so you cannot modify it or update it and I would recommend that you don't use it at all.
#REMOVE PYTHON ON MAC MAC OS#
This article will help you to set up a Python virtual environment on Mac OS or your Macbook.
