Error while installing crewai and crewai tools

I have been using the crewai template for my agents but since today i have been getting the following error ie while building the wheel

Showing the command and only the section where the error occurred:

base) PS C:\Users\viv_k\crewai-examples\PLAY GROUND\TestCase> pip install -U crewai[tools]

File "C:\Users\viv_k\AppData\Local\Temp\pip-build-env-6gfi0kj4\overlay\Lib\site-packages\pkg_resources\__init__.py", line 2191, in <module>
register_finder(pkgutil.ImpImporter, find_on_path)
^^^^^^^^^^^^^^^^^^^
AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'?
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

× Getting requirements to build wheel did not run successfully.

I encountered some error with mismatch in token. Any help would be highly appreciated .

try installing like this:

pip install -U 'crewai[tools]'

here’s the docs for reference: Installation - CrewAI

I tried exactly the same way mentioned in the crewai documentation. I have five this earlier this week and I was sble to run the agent . But today I am facing this issue.

What system are you using; windows?
