Hello, all. I'm having trouble getting the dagit Hello World to work on my Windows conda installation. I've made a conda environment called dagster, then conda installed pip in the environment and pip installed dagster and dagit in the environment. I am able to successfully run
dagster pipeline execute -f hello_world.py -n hello_world_pipeline
in the environment, but running
dagit -f hello_world.py -n hello_world_pipeline
yields a missing command error:
'dagit' is not recognized as an internal or external command, operable program or batch file.
I've tried doing this in an Anaconda prompt as an administrator, and I've tried adding the
[conda path]/envs/dagster/Scripts
folder (which contains the
dagit-cli
windows executable) to PATH but this still yields the same error. I have also tried creating the env and pip-installing packages while in an administrator prompt, but get the same error. Thank you for your time.

Hi Tommy, I don't have windows currently set up, but let's see how much I can help. So if you do
pip show dagit
you can see where the dagit package is. In that folder
bin/dagit
is the python file that should execute. Could you try and execute that directly and see if it works on windows? I am trying to discern whether this is a pathing issue or if it is just not executable on windows.
here is what that looks like for me https://dagster.phacility.com/P17

Thank you for the response. Which of the python files should I execute?
running
pip show dagit
shows me that dagit lives in
[env path]/Lib/site-packages/
and the parent folder has python scripts
__init__, __main__, app, cli, subscription_server, version
and folders
__pycache__, schema, templates, webapp

oh, i was checking my
-e
editable install for development, let me check a real install
do you see both
dagit
and
dagit-cli
in that Scripts folder?
Copy code
(prod) ~:$ ls /Users/alangenfeld/venvs/prod/bin/dagit*
/Users/alangenfeld/venvs/prod/bin/dagit     /Users/alangenfeld/venvs/prod/bin/dagit-cli

yes, although the
dagit
file has no extension and the
dagit-cli
is an .exe

what happens if you execute those directly?
for context:
dagit-cli
does the real work,
dagit
is a wrapper script that restarts when files have changed for an improved dev experience. If
dagit-cli
works and
dagit
does not you should be able to proceed (while we work on fixing)

when I run
dagit-cli
in the
Scripts
directory, I get the following:

alright so that works, and
dagit
? I think running
dagit-cli -f hello_world.py -n hello_world_pipeline
where you were originally doing the tutorial should unblock you.

running
python dagit
? I get this:
Traceback (most recent call last):
File "dagit", line 66, in <module>
handler.start()
File "C:\Users\tnaugle\AppData\Local\Continuum\anaconda3\envs\dagster\lib\site-packages\watchdog\tricks\__init__.py", line 147, in start

AttributeError: module 'os' has no attribute 'setsid'
Using
dagit-cli
in place of
dagit
for the hello world tutorial works! Thank you so much for your time, Alex.
