Trying to use DbtShellTask on windows but get the following error:
Copy code
[2022-06-27 17:16:15+0200] ERROR - prefect.DbtShellTask | /bin/bash: C:UsersUSERAD~1AppDataLocalTempprefect-6rbqzzlx: No such file or directory
This line in prefect.tasks.shell.py generates a strange path:

with tempfile.NamedTemporaryFile(prefix="prefect-") as tmp:
Running something simple with ShellTask
Copy code
from prefect import Flow
from prefect.tasks.shell import ShellTask

task = ShellTask(log_stderr=True)
with Flow("My Flow") as f:
    # both tasks will be executed in home directory
    contents = task(command='ls')

out = f.run()
gives the same error:

This looks like bash is not in the Windows path?
a
My interpretation is that this file does not exist: C:UsersUSERAD~1AppDataLocalTempprefect-_exffnpu

Oh not even, the path out of your TemporaryFile looks weird
I guess you could use the 
os.subprocess
call inside a task
a
Yes not sure what is the issue with tempfile behaviour, will have to solve it with os.subprocess
