dagster dev not working inside conda env

[nsteins]

Dagster version

1.8.8

What's the issue?

I am not able to run a webserver using the dagster dev command inside a conda env. Inside a fresh environment, running dagster dev yields the error:

Usage: dagster dev [OPTIONS] Try 'dagster dev --help' for help.

Error: The dagster-webserver Python package must be installed in order to use the dagster dev command. If you're using pip, you can install the dagster-webserver package by running "pip install dagster-webserver" in your Python environment.

However dagster-webserver does run correctly as expected

What did you expect to happen?

I expect dagster dev to launch a dagster webserver locally

How to reproduce?

Tested from a fresh environment

conda create -n test_env python=3.10
conda activate test_env
pip install dagster-webserver
dagster dev

It appears that everything is installed and located correctly in the env:

whereis pip dagster dagster-webserver

pip: /usr/local/Caskroom/miniconda/base/envs/test_env/bin/pip dagster: /usr/local/Caskroom/miniconda/base/envs/test_env/bin/dagster dagster-webserver: /usr/local/Caskroom/miniconda/base/envs/test_env/bin/dagster-webserver

The issue was not with locating the code, but the error claiming dagster-webserver was not installed, regardless of commands passed to the command.

However, I am no longer able to reproduce this error, which leads me to believe I had something misconfigured with my environment that has been fixed, so I am closing the issue.
