# Installation
> Get started with CrewAI - Install, configure, and build your first AI crew
### Watch: Building CrewAI Agents & Flows with Coding Agent Skills
Install our coding agent skills (Claude Code, Codex, ...) to quickly get your coding agents up and running with CrewAI.
You can install it with `npx skills add crewaiinc/skills`
## Video Tutorial
Watch this video tutorial for a step-by-step demonstration of the installation process:
## Text Tutorial
**Python Version Requirements**
CrewAI requires `Python >=3.10 and <3.14`. Here's how to check your version:
```bash theme={null}
python3 --version
```
If you need to update Python, visit [python.org/downloads](https://python.org/downloads)
**OpenAI SDK Requirement**
CrewAI 0.175.0 requires `openai >= 1.13.3`. If you manage dependencies yourself, ensure your environment satisfies this constraint to avoid import/runtime issues.
CrewAI uses the `uv` as its dependency management and package handling tool. It simplifies project setup and execution, offering a seamless experience.
If you haven't installed `uv` yet, follow **step 1** to quickly get it set up on your system, else you can skip to **step 2**.
* **On macOS/Linux:**
Use `curl` to download the script and execute it with `sh`:
```shell theme={null}
curl -LsSf https://astral.sh/uv/install.sh | sh
```
If your system doesn't have `curl`, you can use `wget`:
```shell theme={null}
wget -qO- https://astral.sh/uv/install.sh | sh
```
* **On Windows:**
Use `irm` to download the script and `iex` to execute it:
```shell theme={null}
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```
If you run into any issues, refer to [UV's installation guide](https://docs.astral.sh/uv/getting-started/installation/) for more information.
* Run the following command to install `crewai` CLI:
```shell theme={null}
uv tool install crewai
```
If you encounter a `PATH` warning, run this command to update your shell:
```shell theme={null}
uv tool update-shell
```
If you encounter the `chroma-hnswlib==0.7.6` build error (`fatal error C1083: Cannot open include file: 'float.h'`) on Windows, install [Visual Studio Build Tools](https://visualstudio.microsoft.com/downloads/) with *Desktop development with C++*.
* To verify that `crewai` is installed, run:
```shell theme={null}
uv tool list
```
* You should see something like:
```shell theme={null}
crewai v0.102.0
- crewai
```
* If you need to update `crewai`, run:
```shell theme={null}
uv tool install crewai --upgrade
```
This upgrades the **global `crewai` CLI tool** only. To upgrade the `crewai` version inside your project's virtual environment, see [Upgrading CrewAI in a project](/en/guides/migration/upgrading-crewai).
Installation successful! You're ready to create your first crew! 🎉
# Creating a CrewAI Project
We recommend using the `YAML` template scaffolding for a structured approach to defining agents and tasks. Here's how to get started:
* Run the `crewai` CLI command:
```shell theme={null}
crewai create crew
```
* This creates a new project with the following structure:
```
my_project/
├── .gitignore
├── knowledge/
├── 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
```
* Your project will contain these essential files:
| 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 |
| `knowledge/` | Directory for knowledge base |
* Start by editing `agents.yaml` and `tasks.yaml` to define your crew's behavior.
* Keep sensitive information like API keys in `.env`.
* Before you run your crew, make sure to run:
```bash theme={null}
crewai install
```
* If you need to install additional packages, use:
```shell theme={null}
uv add
```
As a supply-chain security measure, CrewAI's internal packages use `exclude-newer = "3 days"` in their `pyproject.toml` files. This means transitive dependencies pulled in by CrewAI won't resolve packages released less than 3 days ago. Your own direct dependencies are not affected by this policy. If you notice a transitive dependency is behind, you can pin the version you want explicitly in your project's dependencies.
* To run your crew, execute the following command in the root of your project:
```bash theme={null}
crewai run
```
