[BUG] Can't import crewai -> PydanticUserError

[Michal-Mikolas]

Description

Because I have some issues with older version of CrewAI which make it unusable, I tried to install the newest Python, create new virtual environment and install the newest CrewAI version. However I can't import it because it throws exception.

Steps to Reproduce

1. Create fresh virtual environment using python -m venv
2. Install current CrewAI with pip
3. Try to import crewai

Expected behavior

It should import the crewai without any error.

Screenshots/Code snippets

Python file:

import crewai

Output:

Exception has occurred: PydanticUserError
The `__modify_schema__` method is not supported in Pydantic v2. Use `__get_pydantic_json_schema__` instead in class `SecretStr`.

Same problem here. Tried installing it fresh today. This happened after I installed langchain-openai. Those were the two packages installed in the environment.

pip install --upgrade crewai crewai-tools does this help? It should fix dependencies and their versions.

[Michal-Mikolas]

After deleting my .venv folder, creating fresh one and installing crewai again, it works now. I even tried to install langchain-openai as well, no problem.

@BurgosNY Can you please try it again like this?

[Michal-Mikolas]

P.S. @BurgosNY I think you don't need to install langchain-openai manually anymore since CrewAI now uses LiteLLM for handling the communication with selected model: https://docs.crewai.com/how-to/LLM-Connections/
