Description

There is a dependency conflict in requirements.txt that prevents installation with package managers like uv and potentially causes issues with pip.

The Conflict

• Pillow version specified: pillow~=11.1.0 (means >=11.1.0, <12.0.0)
• crawl4ai requirement: crawl4ai~=0.6.3 requires pillow>=10.4,<11.0

These version constraints are mutually exclusive.

Error Output

When using uv pip install -r requirements.txt:

× No solution found when resolving dependencies:
╰─▶ Because crawl4ai==0.6.3 depends on pillow>=10.4,<11.dev0 and only the
    following versions of crawl4ai are available:
        crawl4ai<=0.6.3
        crawl4ai>0.7.dev0
    we can conclude that crawl4ai>=0.6.3,<0.7.dev0 depends on
    pillow>=10.4,<11.dev0.
    And because you require pillow>=11.1.0,<11.2.dev0 and
    crawl4ai>=0.6.3,<0.7.dev0, we can conclude that your requirements are
    unsatisfiable.

Environment

• Python version: 3.12.10
• Package manager: uv 0.8.19 (also affects pip)
• OS: macOS Darwin 24.3.0 (ARM64)
• Date discovered: 2025-01-19

Steps to Reproduce

1. Clone the repository
2. Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
3. Create virtual environment: uv venv --python 3.12
4. Activate venv: source .venv/bin/activate
5. Try to install: uv pip install -r requirements.txt

Suggested Solutions

Option 1: Downgrade Pillow

Change line 13 in requirements.txt:

- pillow~=11.1.0
+ pillow~=10.4

Option 2: Update crawl4ai

Check if a newer version of crawl4ai supports Pillow 11.x and update accordingly.

Option 3: Use flexible versioning

- pillow~=11.1.0
+ pillow>=10.4

This allows the dependency resolver to find a compatible version.

Impact

This blocks new users from setting up OpenManus following the documented installation instructions, particularly when using the recommended uv package manager from Method 2 in the README.
