Hi all! I just wanted to have a prefect3 version on my MacOS 14.6.1 to test. Python 3.11.6 and in venv I ran ‘pip install -U prefect’ and completed. To verify I ran prefect version and get errors. Please help me like prefect again... (thanks!) Error: Traceback (most recent call last): File “/Users/common/work/prefect/bin/prefect”, line 5, in <module> from prefect.cli import app File “/Users/common/work/prefect/lib/python3.11/site-packages/prefect/cli/__init__.py”, line 12, in <module> import prefect.cli.shell File “/Users/common/work/prefect/lib/python3.11/site-packages/prefect/cli/shell.py”, line 16, in <module> from prefect import flow File “<frozen importlib._bootstrap>“, line 1229, in _handle_fromlist File “/Users/common/work/prefect/lib/python3.11/site-packages/prefect/__init__.py”, line 117, in getattr module = import_module(module_name, package=package) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File “/opt/homebrew/Cellar/python@3.11/3.11.6/Frameworks/Python.framework/Versions/3.11/lib/python3.11/importlib/__init__.py”, line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File “/Users/common/work/prefect/lib/python3.11/site-packages/prefect/main.py”, line 55, in <module> prefect.logging.configuration.setup_logging() File “/Users/common/work/prefect/lib/python3.11/site-packages/prefect/logging/configuration.py”, line 71, in setup_logging config = load_logging_config( ^^^^^^^^^^^^^^^^^^^^ File “/Users/common/work/prefect/lib/python3.11/site-packages/prefect/logging/configuration.py”, line 41, in load_logging_config template.substitute(current_settings.to_environment_variables()) File “/opt/homebrew/Cellar/python@3.11/3.11.6/Frameworks/Python.framework/Versions/3.11/lib/python3.11/string.py”, line 121, in substitute return self.pattern.sub(convert, self.template) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File “/opt/homebrew/Cellar/python@3.11/3.11.6/Frameworks/Python.framework/Versions/3.11/lib/python3.11/string.py”, line 114, in convert return str(mapping[named]) ~~~~~~~^^^^^^^ KeyError: ‘PREFECT_LOGGING_SERVER_LEVEL’

Did you have an older prefect on your machine before installing prefect 3? Sometimes I have to reset my profiles in ~/.prefect if some sort of configuration/settings change happened.

@Janet Carson yup, that did the trick. I’ll start testing but I did have errors on our install on a linux server but I will check for similar issues - thanks, sometimes hours can be saved with one message!
