I keep getting this error no matter what I do: ImportError: cannot import name 'EnvVar' from 'crewai.tools'

[AImicrowave]

Hi,
I’m trying to install and run CrewAI Studio on my Mac, but I keep running into dependency issues with the crewai and crewai-tools packages. The versions specified in the README (crewai==0.22.6 and crewai-tools==0.0.51) are not available on PyPI, and the latest available versions are not compatible with each other or with CrewAI Studio’s codebase.
Specifically, I get this error:
ImportError: cannot import name 'EnvVar' from 'crewai.tools'
It seems that the latest crewai_tools package expects an EnvVar symbol in crewai.tools, but it does not exist in the latest crewai package.
Could you please provide:
A working requirements.txt or list of package versions that are known to work together?
Or, if possible, the old .whl files for crewai==0.22.6 and crewai-tools==0.0.51?
Or, ideally, an updated version of CrewAI Studio that works with the latest crewai and crewai-tools?
Thank you so much for your help and for making this project open source!

Hi, are you sure you are using this repository and not some fork of it? I didn't put any version specifications neighter to readme or requirements.txt. Are you using venv, conda or docker? What is your python version?

[AImicrowave]

Hi!
Thank you for your quick response.
I am using the official CrewAI Studio repository (not a fork).
I set up a virtual environment using venv.
My Python version is 3.11.
I installed the dependencies using pip install -r requirements.txt and then installed crewai and crewai-tools from PyPI (since there are no version specs in the repo).
When I run the app, I get this error:
ImportError: cannot import name 'EnvVar' from 'crewai.tools'
(/Users/"my name"/Downloads/CrewAI-Studio-main/venv/lib/python3.11/site-packages/crewai/tools/init.py)
It seems the latest crewai_tools package expects an EnvVar symbol in crewai.tools, but it doesn’t exist in the latest crewai package.
Do you have a list of package versions that are known to work, or any advice on which versions of crewai and crewai-tools I should use?
Thank you very much.

I didn't try using conda yet so i'm going to try doing it with conda (I have an older mac so Docker doesn't work)

[strnad]

maybe try to install it using pip without cache (--no-cache), or it could be because of python version... I have these packages and it works without any problem:

Thank you for helping me, I will try using these versions and I will text here if it was succesful

[AImicrowave]

Hi again,
Thank you for your previous help and for sharing your working pip freeze output. I’ve tried to match your environment as closely as possible (using Python 3.12.1, crewai==0.140.0, crewai-tools==0.49.0, and the rest of your package versions).
However, I keep running into a dependency conflict that pip cannot resolve:
crewai==0.140.0 requires onnxruntime==1.22.0, but that version is not available for my platform (macOS, Python 3.12.1).
chromadb==0.5.23 requires onnxruntime>=1.14.1, which would work with the available versions, but not with the strict pin to 1.22.0 from crewai. Pip gives this error: ERROR: Cannot install -r requirements.txt (line 29) and -r requirements.txt (line 34) because these package versions have conflicting dependencies.
The conflict is caused by:
chromadb 0.5.23 depends on onnxruntime>=1.14.1
crewai 0.140.0 depends on onnxruntime==1.22.0
ERROR: ResolutionImpossible
I’ve tried removing the version pin for onnxruntime, but then crewai still requires 1.22.0 specifically, which isn’t available for my system.
Is there a workaround for this, or could you suggest a set of versions (or a requirements file) that would work on macOS? Or is there a way to relax the onnxruntime version requirement in crewai?
Thank you so much for your help and for maintaining this project!

The problem in issue #98 is a version compatibility and missing symbol error.
The latest crewAI_tools package expects an EnvVar symbol in crewai.tools, but that symbol no longer exists in the current package version.

This means:

• The versions listed in the README (crewAI = 0.22.6 and crewAI_tools = 0.5.1) are either not available or incompatible.
• Installing crewAI_tools from PyPI without pinning the version results in ImportError: cannot import name 'EnvVar' from 'crewAI.tools'.
• The error will persist unless a matching pair of crewAI and crewAI_tools versions is used, or the code is updated to remove the dependency on EnvVar.

Using Windows 11. CrewAI Studio installed in d:\code\CrewAI-Studio.
System python: 3.12. (in C:\Python312

Using pip / venv type of environment (as opposed to conda or docker).
Ran install_venv.bat. No issues that I can see.

Ran through install, then run the run_venv.bat file. I am getting this error:
