Installation |
Get started with CrewAI - Install, configure, and build your first AI crew |
wrench |
CrewAI requires Python >=3.10 and <3.13
. Here's how to check your version:
python3 --version
If you need to update Python, visit python.org/downloads
Before installing CrewAI, it's recommended to set up a virtual environment. This helps isolate your project dependencies and avoid conflicts.
Choose your preferred method to create a virtual environment: **Using venv (Python's built-in tool):**
```shell Terminal
python3 -m venv .venv
```
**Using conda:**
```shell Terminal
conda create -n crewai-env python=3.12
```
</Step>
<Step title="Activate the Virtual Environment">
Activate your virtual environment based on your platform:
**On macOS/Linux (venv):**
```shell Terminal
source .venv/bin/activate
```
**On Windows (venv):**
```shell Terminal
.venv\Scripts\activate
```
**Using conda (all platforms):**
```shell Terminal
conda activate crewai-env
```
</Step>
Now let's get you set up! 🚀
Install CrewAI with all recommended tools using either method: ```shell Terminal pip install 'crewai[tools]' ``` or ```shell Terminal pip install crewai crewai-tools ``` <Note>
Both methods install the core package and additional tools needed for most use cases.
</Note>
</Step>
<Step title="Upgrade CrewAI (Existing Installations Only)">
If you have an older version of CrewAI installed, you can upgrade it:
```shell Terminal
pip install --upgrade crewai crewai-tools
```
<Warning>
If you see a Poetry-related warning, you'll need to migrate to our new dependency manager:
```shell Terminal
crewai update
```
This will update your project to use [UV](https://github.com/astral-sh/uv), our new faster dependency manager.
</Warning>
<Note>
Skip this step if you're doing a fresh installation.
</Note>
</Step>
<Step title="Verify Installation">
Check your installed versions:
```shell Terminal
pip freeze | grep crewai
```
You should see something like:
```markdown Output
crewai==X.X.X
crewai-tools==X.X.X
```
<Check>Installation successful! You're ready to create your first crew.</Check>
</Step>
This creates a new project with the following structure:
<Frame>
```
my_project/
├── .gitignore
├── pyproject.toml
├── README.md
├── .env
└── src/
└── my_project/
├── __init__.py
├── main.py
├── crew.py
├── tools/
│ ├── custom_tool.py
│ └── __init__.py
└── config/
├── agents.yaml
└── tasks.yaml
```
</Frame>
<Tip>
UV is our preferred package manager as it's significantly faster than pip and provides better dependency resolution.

| File | Purpose |
| --- | --- |
| `agents.yaml` | Define your AI agents and their roles |
| `tasks.yaml` | Set up agent tasks and workflows |
| `.env` | Store API keys and environment variables |
| `main.py` | Project entry point and execution flow |
| `crew.py` | Crew orchestration and coordination |
| `tools/` | Directory for custom agent tools |
<Tip>
Start by editing `agents.yaml` and `tasks.yaml` to define your crew's behavior.
Keep sensitive information like API keys in `.env`.
