Create python virtual enviroments on Windows

Sun 11 June 2017 | tags: Python
  1. Before creating the venv you will need to open a PowerShell terminal as root and run the commands below to allow the script that activates the virtual env to run:

    cd ..
    Set-ExecutionPolicy Unrestricted
    
  2. Create the venv. Run in a terminal as a normal user: python3 -m venv .venv If the creation fails due to python3 not found, check that:

    • python3 was added to your your PATH during install.
    • Make a copy of your python.exe executable into python3.exe
  3. Enable the venv: .venv\Scripts\activate

  4. Install the dependencies: pip install -r requires.txt

  5. Install the tests dependencies: pip install -r tests_requires.txt

  6. To install libraries that requires compiled files (like lxml) you can use the wheel files. Most libraries have such a file on pypi so you can install them directly with pip. If not, check this site to find the proper wheel file for your platform and your version of Python. Then to install it, download it and run pip install \path\to\the\weeh.whl
