1A. INSTALLING PYTHON, PIP, ON WINDOWS USING CHOCOLATEY AND PYENV-WIN
Chocolatey is the Windows package manager.
Open PowerShell in Administrative mode (Windows key ⊞ » type “Windows Powershell” » right click » “Run as Administrator”).
If PowerShell doesn’t show up, install PowerShell
Once PowerShell is running, run the following command. It may be easiest to copy and paste to avoid typos.
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
Install Pyenv-Win
Pyenv-Win is a Python installation manager, which allows one to install multiple versions of python on their computer.
still in Powershell
choco install pyenv-win
You may be prompted to approve the installation with the following text (or similar):
Do you want to run the script?([Y]es/[A]ll - yes to all/[N]o/[P]rint):
Here you can enter A and press Enter
Install sudo
Also install sudo, which allows you to run command-line applications (like choco) with administration rights without opening an administrator PowerShell window:
choco install sudo
Again, you will be asked to confirm this is what you want by entering A and pressing Enter.
Install Python via Pyenv
New POWERSHELL
pyenv install 3.8.5
pyenv global 3.8.5
pyenv local 3.8.5
Set PATH to run these from the PowerShell command line
New POWERSHELL
sudo setx /m PATH "%HOMEPATH%\.pyenv\pyenv-win\versions\3.8.5;%PATH%"
sudo setx /m PATH "%HOMEPATH%\.pyenv\pyenv-win\versions\3.8.5\Scripts;%PATH%"
sudo setx /m PATH "%HOMEPATH%\appdata\roaming\python\python38\site-packages;%PATH%"
sudo setx /m PATH "%HOMEPATH%\AppData\Roaming\Python\Python38\Scripts;%PATH%"
Create an Alias for Python (optional)
The rest of this tutorial uses the command python3 when executing python commands; on macOS you can usually use the commands python or python3 interchangeably, but not always. Windows will sometimes send you to the Microsoft Store to download a different version of Python if you enter python3. To follow the rest of the tutorial verbatim, tell Windows to treat the command python3 as an alias for python by entering the following command in PowerShell:
Set-Alias python3 python
Or, you can remind yourself that subsequent references to python3 in this tutorial should be run as python in Windows.
You can now close your administrative shell by typing exit and pressing Enter.
Install Handprint
New CMD or POWERSHELL
pip install handprint
