[garethbrickman]

What's the issue?

After installing the latest version of dagster and dagster-webserver (1.9.10), running dagster dev in Windows results in:

PermissionError: [Errno 13] Permission denied: 'C:\\...\\Temp\\tmpzpovtxtw'

This is despite the Windows user having administrator and/or full access to all the folders and files.

What did you expect to happen?

dagster dev should start without error

How to reproduce?

Also happens if you scaffold a new project by running: dagster project scaffold --name test_dagster_project

One short term workaround for this while we fix the underlying file permissions issue, is to run dagster dev with the --use-legacy-code-server-behavior argument or downgrade to dagster 1.9.9.

I'm having the same issue. Even though i have full access to the folders and files, it's not running. How to solve it?

@zoezhouDA Until the fix for this is released, you can run dagster dev --use-legacy-code-server-behavior or downgrade your Dagster version to 1.9.9 or earlier.

This should be fixed in dagster 1.9.11, released earlier today.
