mkdir ~/envs
cd ~/envs    # move to envs directory
/usr/local/bin/python3.11 -m venv bottle  # create virtual environment using venv
cd bottle
source bin/activate  # activate the environment
pip --version        # double-check the pip version

## On Windows, you typically navigate to the Scrips folder to activate the virtual environment:
python -m venv myenv
cd myenv\Scripts
activate.bat

######  Installing Same Packages as Prior Python Version  ######
pip freeze > installed.txt  (on older Python version)
pip install -r installed.txt (current Python version)

### Installing Packages using pip ###
pip install <package-name>
pip install git+https://github.com/scikit-learn/scikit-learn.git

### Installing the master branch
pip install 'ibis-framework[duckdb]@git+https://github.com/ibis-project/ibis@master'


# If using miniconda3, add conda-forge channel:
conda config --add channels conda-forge


### To add environment variables to your profile
edit .profile file, then:
export <your_environment_variable_name>=<value>

To "update" the .profile file, do: source .profile
