Step 1: get pyenv-win #

LINK: https://github.com/pyenv-win/pyenv-win#get-pyenv-win

My preferred appraoch: choco install pyenv-win

Ensure you can run:

pyenv --version

Step 2: install preferred versions of python #


pyenv install 3.6.8 3.8.10 etc.

If it’s miniconda, you’ll have to do a bit more work on the windows version: https://github.com/pyenv-win/pyenv-win/issues/25

  • Download the latest miniconda
  • Do the user installation (don’t set any variables to PATH)
  • Installation directory should be:
    • C:/Users/MYUSERNAME/.pyenv/pyenv-win/versions/anaconda3-2020.11

Step 3: Set your dbt project to use your pyenv dir #

Within your dbt project directory:

pyenv local 3.8.10 (your version here)

Step 3: Create a venv for your dbt project #

Per usual with python, create a venv with:

python -m venv dbt_venv

Activate it with: dbt_venv\Scripts\activate.bat

If you already have a requirements txt file:

pip install -r requirements.txt

Otherwise: pip install dbt==0.20.1 (your version here)

Step 4: Set this to be the default python in this vscode workspace: #

create .vscode as a directory if it does not exist. in a file called settings.json, drop in:

    "python.defaultInterpreterPath": "dbt_venv\\Scipts\\python.exe"

Step 5: reload / relaunch and REJOICE #

Now when you open this folder, this project, etc, it will always use your pyenv local python version and the specific venv within the project dir.

You can launch terminal (with your venv pre-loaded) any time now by hitting: `Ctrl+Shift+``

Should anything ever happen to the installation, easily re-clone the repo / dir and run the following:

git clone myrepo.git
cd myrepo
pyenv local 3.8.10
python -m venv dbt_venv
pip install -r requirements.txt

And you’re back up and running with the original python / dbt environment according to spec.
