• Install virtualenv: apt install python3-virtualenv.
• Setup virtualenv: apt install python3-venv.

python3 -m venv venv # If this fails you probably need to add Python3 to your PATH.
virtualenv venv -p python3
source ./venv/bin/activate
python3 -m pip install -r requirements.txt

Windows

• NOTE: Only Python 3.9 or later is supported!
• If needed, install Python:
  • Download Python here.
  • When installing, enable "add Python to PATH".
  • If the Python version is at least 3.10, a default local install works.
  • If the Python version is 3.9, choose "Custom installation", keep the defaults on the Optional Features page, and choose "Install for all users" in the Advanced Options page.
• Start Terminal, PowerShell, cmd, or your preferred command prompt.
• Upgrade pip: py -m pip install --upgrade pip.
• Download the repo into lichess-bot directory.
• Navigate to the directory: cd [folder's address] (for example, cd C:\Users\username\repos\lichess-bot).
• Install virtualenv: py -m pip install virtualenv.
• Setup virtualenv:

py -m venv venv # If this fails you probably need to add Python3 to your PATH.
venv\Scripts\activate
pip install -r requirements.txt

PowerShell note: If the activate command does not work in PowerShell, execute Set-ExecutionPolicy RemoteSigned first and choose Y there (you may need to run Powershell as administrator). After you execute the script, change execution policy back with Set-ExecutionPolicy Restricted and pressing Y.

• Copy config.yml.default to config.yml.
