Hi all, I set up the dagster dev environment in my labtop and try to run some test with:

python -m pytest python_modules/dagster/dagster_tests

based on the contribution page. However, import error raised as below:

ImportError while loading conftest '/Users/dong.kim/Documents/projects/dagster/python_modules/dagster/dagster_tests/conftest.py'.
python_modules/dagster/dagster_tests/conftest.py:9: in <module>
    from dagster_test.dagster_core_docker_buildkite import (
    ModuleNotFoundError: No module named 'dagster_test'

it looks like that

dagster_test

package was not imported properly. Do you have any suggestion how i can fix this error? ``````

hey @Dong Kim - I think you can fix this with

pip install -e python_modules/dagster-test

@sandy Thanks. That works. I did not know that

python_modules/dagster-test

needed to be install in dev mode.
