How to create a virtual environment in Python?

Question

Can anyone tell me how to create a virtual environment in Python?

Answer 1

For creating a virtual environment in Python, you can use pip.

• For a Windows machine, you can follow the below steps:

First, update your pip:

py -m pip install --upgrade pip

Then, write the below code:

py -m pip --version

pip 9.0.1 from c:\Python36\lib\site-packages (Python 3.6.1)

• For Linux or macOS, you can use the following:

Use the system pip to load the operating system into its memory:

Python3 -m pip install --user --upgrade pip 

Python3 -m pip --version 

pip 9.0.1 from $HOME/.local/lib/Python3.6/site-packages (Python 3.6)

Now, after installing pip, to create a virtual environment, you need to browse to your project’s folder and run venv. If you are having the Python 2 version, then you can just replace venv with virtualenv in the below commands. 

• For Windows, the command is: 

py -m venv env

• For macOS and Linux, the command is: 

Python3 -m venv env 

After creating the VMs, now, you have to activate them with the below commands.

• For Windows: 

.\env\Scripts\activate

• For macOS and Linux: 

source env/bin/activate
