Overview

This Conda package uses activation/deactivation scripts to set the environment variable PYTHONPATH="" when activating a Conda environment, effectively insulating the Conda environment from Python modules provided by this variable.

Installation

The package is hosted on Anaconda Cloud. It can be installed with

conda install merv::envvar-pythonpath-null

Users wishing to have PYTHONPATH="" set for all environments by default can use

conda config --add create_default_packages merv::envvar-pythonpath-null

which will include this package automatically in all future environments at environment creation.

Reuse and Repurposing

This package is a proof-of-concept to demonstrate managing environment variables in Conda environments through the "unit of computation" of Conda, which is the Conda package. It is released under a CC0 license (i.e., public domain). Feel free to use this repository as an outline for similar packages.

The environment variables are set/unset in the recipe/[de]activate.{bat,sh} files. While there is not a standing convention for packages managing environment variables, this uses the template envvar-<variable_name>-<value>.

The repository includes a GitHub Workflow that builds and uploads the package to Anaconda Cloud. For the uploading portion to work, users should adjust the ANACONDA_USER variable in the conda-build.yml workflow file and need to set an ANACONDA_TOKEN repository secret corresponding to an access token for their Anaconda Cloud account with the "Allow all API operations" permission.
