    You can use copy and paste it in another directory or computer, but its not a best way to use virtualenv. you better notedown your requirements in any txt file like requirement.txt and run the use pip freeze > requirement.txt to write all the requirements in requirement.txt

    script using pip.

    pip install -r requirement.txt

    If your goal is to make sure that everything including your OS are the same in both computers then you can use virtual box and vagrant on top to setup a virtual box and then create your virtualenv using either requirements or any other way to reproduce it.

    You should not. The other computer can have a different operating system, other packages or package versions installed, so copying the files will not work.

    The point of a virtual environment is to be able to replicate it everywhere you need it.

    Make a script which installs all necessary dependencies from a requirements.txt file and use it.

    Use pip freeze > requirements.txt to get the list of all python packages installed. Then install the dependencies in another virtual environment on another computer using pip install -r requirements.txt.

    If you want the exact environment, including system packages, on another computer, use Docker.
