<Note>
  **Python Version Requirements**

CrewAI requires `Python >=3.10 and <3.14`. Here's how to check your version:

```bash
python3 --version
```

If you need to update Python, visit [python.org/downloads](https://python.org/downloads)

</Note>

<Note>
  **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.

</Note>

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**.

<Steps>
    <Step title="Install uv">
      - **On macOS/Linux:**

        Use `curl` to download the script and execute it with `sh`:

        ```shell
        curl -LsSf https://astral.sh/uv/install.sh | sh
        ```
        If your system doesn't have `curl`, you can use `wget`:

        ```shell
        wget -qO- https://astral.sh/uv/install.sh | sh
        ```

      - **On Windows:**

        Use `irm` to download the script and `iex` to execute it:

        ```shell
        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.
    </Step>

    <Step title="Install CrewAI 🚀">
      - Run the following command to install `crewai` CLI:
        ```shell
        uv tool install crewai
        ```
          <Warning>
            If you encounter a `PATH` warning, run this command to update your shell:
            ```shell
            uv tool update-shell
            ```
          </Warning>

          <Warning>
            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++*.
          </Warning>

      - To verify that `crewai` is installed, run:
        ```shell
        uv tool list
        ```
      - You should see something like:
        ```shell
        crewai v0.102.0
        - crewai
        ```
      - If you need to update `crewai`, run:
        ```shell
        uv tool install crewai --upgrade
        ```
      <Note>
        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).

# Creating a CrewAI Project

`crewai create crew` now creates a JSON-first crew project. Agents live in `agents/*.jsonc`, tasks and crew-level settings live in `crew.jsonc`, and `crewai run` loads that JSON definition directly.

<Steps>
  <Step title="Generate Project Scaffolding">
    - Run the `crewai` CLI command:
      ```shell
      crewai create crew <your_project_name>
      ```

    - This creates a new project with the following structure:
      ```
      my_project/
      ├── .gitignore
      ├── .env
      ├── agents/
      │   └── researcher.jsonc
      ├── crew.jsonc
      ├── knowledge/
      ├── pyproject.toml
      ├── README.md
      ├── skills/
      └── tools/
      ```

    - If you need the older Python/YAML scaffold with `crew.py`, `config/agents.yaml`, and `config/tasks.yaml`, run:
      ```shell
      crewai create crew <your_project_name> --classic
      ```

  </Step>

  <Step title="Customize Your Project">
    - Your project will contain these essential files:
      | File | Purpose |
      | --- | --- |
      | `crew.jsonc` | Configure the crew, task order, process, and input defaults |
      | `agents/*.jsonc` | Define each agent's role, goal, backstory, LLM, tools, and behavior |
      | `.env` | Store API keys and environment variables |
      | `tools/` | Optional Python files for `custom:<name>` tools |
      | `knowledge/` | Optional knowledge files for agents |
      | `skills/` | Optional skill files applied to the crew |

    - Start by editing `crew.jsonc` and the files in `agents/` to define your crew's behavior.
    - Use `{placeholder}` values in agent and task text, then set defaults in `crew.jsonc` under `inputs`. When you run `crewai run`, the CLI prompts for any missing values.
    - Keep sensitive information like API keys in `.env`.

  </Step>

  <Step title="Run your Crew">
    - Before you run your crew, make sure to run:
      ```bash
      crewai install
      ```
    - If you need to install additional packages, use:
      ```shell
      uv add <package-name>
      ```
      <Note>
        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.
      </Note>
    - To run your crew, execute the following command in the root of your project:
      ```bash
      crewai run
      ```
  </Step>
</Steps>
