For Windows Users: Step-by-step guide on how manage your Python projects with pyenv-win.

What is Pyenv?

Install and manage multiple Python versions on your computer. This makes it easier to share your code with others, deploy your code and generally avoid all those annoying table-flipping moments!

1. Open a new PowerShell window, and make sure you select the “Run as Administrator” option:

2. Run this command in the PowerShell prompt:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine

3. Now run this to install pyenv-win install:

Invoke-WebRequest -UseBasicParsing -Uri "https://raw.githubusercontent.com/pyenv-win/pyenv-win/master/pyenv-win/install-pyenv-win.ps1" -OutFile "./install-pyenv-win.ps1"; &"./install-pyenv-win.ps1"

If everything went well, you should see this:

4. List out all available Python versions:

pyenv install --list

5. If you don’t see the version you want in the list, run the pyenv update command:

pyenv update

6. Now install the specific Python version:

pyenv install 3.10.7

7. Set the global (system-wide) Python version with the global keyword:

pyenv global 3.10.7

8. Verify that your global system is now using the version you just set:

python -V

9. Now you can use the localkeyword to set the application-specific Python version in the root of your project directory:

pyenv local 3.10.7

(This command will automatically create a .python-version file in your project).
