ERROR: pip’s dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.  
langchain-google-genai 2.0.0 requires langchain-core\<0.4,\>=0.3.0, but you have langchain-core 0.2.40 which is incompatible.  
langchain-google-vertexai 2.0.0 requires langchain-core\<0.4,\>=0.3.0, but you have langchain-core 0.2.40 which is incompatible.

How do I fix this issue, (it occurs when I run pip install crewai after pip install langchain-google-genai)? I want to use crewai with langchain-google-genai to work with Gemini as the LLM. Is there another way to use Gemini as an LLM besides this method?

Thanks.

Hey @theg8

## I had the same problem since I use Gemini 1.5 flash as my llm manager. You don’t need to use langchain anymore. I also don’t use langchain-google-genai anymore as it doesn’t work either. I had to uninstall poetry, clear cache, reinstall poetry, reinitialize with poetry. I dont know if this was all needed but eventually helped me resolve the issue same issue you’re having. I also updated my pyproject.toml to include the following before running poetry install again: -------------------pyproject.toml--------------------- [tool.poetry.dependencies] python = “\>=3.10,\<=3.13” crewai = “^0.60.00” # Added this line filelock = “\*” # Added this line

Here’s my current set-up for the crewai.py file that works in 0.60.00 (with Gemini)

import os  
from crewai import Agent, Crew, Process, Task  
from crewai.project import CrewBase, agent, crew, task  
from langchain\_community.llms import OpenAI, Ollama  
from dotenv import load\_dotenv  
import litellm # Added for using google API for Gemini  
from crewai\_tools import SerperDevTool

search\_tool = SerperDevTool()

load\_dotenv()

# Set the Google API key for LiteLLM to use Gemini LLM Models

litellm.api\_key = os.getenv(‘GOOGLE\_API\_KEY’)

I set up a basic crew that uses local models and gemini llm manager if needed. It also accepts TOPIC user input instead of hard coding. Make’s it easier to use. Here’s the repo.

Hope that helps!

I would reinstall your crew to latest version in a fresh ENV as crewai no longer has langchain as a dependency

Oh, I see. Thank you so much! Can I ask how I can use Gemini as the LLM in the CrewAI framework?

If it’s not too much trouble, I would like to ask a bit more, such as how to set the model name and model temperature for Gemini 1.5 Flash.

Thank you so much. I’m new to this. 😭

See here for all models: [https://models.litellm.ai](https://models.litellm.ai)

For google flash ar you going through vertex or google dev?

Assign to your agent for vertex AI flash

```auto
llm='gemini-1.5-flash'

```

OR for google Dev

```auto
llm='gemini/gemini-1.5-flash'

```

I got this error. How do I fix it?

Give Feedback / Get Help: `https://github.com/BerriAI/litellm/issues/new`  
LiteLLM.Info: If you need to debug this error, use `litellm.set_verbose=True`.

Here is the code I used:  
import os  
from dotenv import load\_dotenv  
load\_dotenv()  
os.environ[“GOOGLE\_APPLICATION\_CREDENTIALS”] = os.getenv(“GOOGLE\_APPLICATION\_CREDENTIALS”)  
os.environ[“temperature”] = “0.0”  
os.environ[“top\_p”] = “0.1”

llm=‘gemini-1.5-flash’ at agent

Sorry, my mistake. This thing always appears, and after that, the work results in an error like this:

BadRequestError: litellm.BadRequestError: VertexAIException BadRequestError - { “error”: { “code”: 400, “message”: “Request contains an invalid argument.”, “status”: “INVALID\_ARGUMENT” } }
