--- title: Installation description: Get started with CrewAI - Install, configure, and build your first AI crew icon: wrench mode: "wide" --- ### 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 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 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. - Run the following command to install `crewai` CLI: ```shell uv tool install crewai ``` If you encounter a `PATH` warning, run this command to update your shell: ```shell 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 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 ``` 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 `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. - Run the `crewai` CLI command: ```shell crewai create crew ``` - 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 --classic ``` - 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:` 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`. - Before you run your crew, make sure to run: ```bash crewai install ``` - If you need to install additional packages, use: ```shell 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 crewai run ``` ## Enterprise Installation Options For teams and organizations, CrewAI offers enterprise deployment options that eliminate setup complexity: ### CrewAI AMP (SaaS) - Zero installation required - just sign up for free at [app.crewai.com](https://app.crewai.com) - Automatic updates and maintenance - Managed infrastructure and scaling - Build Crews with no Code ### CrewAI Factory (Self-hosted) - Containerized deployment for your infrastructure - Supports any hyperscaler including on prem deployments - Integration with your existing security systems Learn about CrewAI's enterprise offerings and schedule a demo ## Next Steps Follow the quickstart to scaffold a Flow, run a one-agent crew, and produce a report.
