Question: I have a local python project called jive that I would like to use in an another project. My current method of using jive in other projects is to activate the conda env for the project, then move to my jive directory and use python setup.py install. This works fine, and when I use conda list, I see everything installed in the env including jive, with a note that jive was installed using pip. But what I really want is to do this with full conda. When I want to use jive in another project, I want to just put jive in that projects environment.yml. So I did the following:  write a simple meta.yaml so I could use conda-build to build jive locally build jive with conda build . I looked at the tarball that was produced and it does indeed contain the jive source as expected In my other project, add jive to the dependencies in environment.yml, and add 'local' to the list of channels. create a conda env using that environment.yml.  When I activate the environment and use conda list, it lists all the dependencies including jive, as desired. But when I open python interpreter, I cannot import jive, it says there is no such package. (If use python setup.py install, I can import it.) How can I fix the build/install so that this works? Here is the meta.yaml, which lives in the jive project top level directory: package: name: jive version: "0.2.1" source: path: . build: script: python -m pip install --no-deps --ignore-installed . requirements: host: - python>=3.5 - pip - setuptools run: - python>=3.5 - numpy - pandas - scipy - seaborn - matplotlib - scikit-learn - statsmodels - joblib - bokeh test: imports: jive  And here is the output of conda build .

Answer: The immediate error is that the build is generating a Python 3.10 version, but when testing Conda doesn't recognize any constraint on the Python version, and creates a Python 3.9 environment. I think the main issue is that python >=3.5 is only a valid constraint when doing noarch builds, which this is not. That is, once a package builds with a given Python version, the version must be constrained to exactly that version (up through minor). So, in this case, the package is built with Python 3.10, but it reports in its metadata that it is compatible with all versions of Python 3.5+, which simply isn't true because Conda Python packages install the modules into Python-version-specific site-packages (e.g., lib/python-3.10/site-packages/jive). Typically, Python versions are controlled by either the --python argument given to conda-build or a matrix supplied by the conda_build_config.yaml file (see documentation on "Build variants"). Try adjusting the meta.yaml to something like package: name: jive version: "0.2.1" source: path: . build: script: python -m pip install --no-deps --ignore-installed . requirements: host: - python - pip - setuptools run: - python - numpy - pandas - scipy - seaborn - matplotlib - scikit-learn - statsmodels - joblib - bokeh  If you want to use it in a Python 3.9 environment, then use conda build --python 3.9 ..
