3. Installation Methods
Open Manus can be installed using two primary methods: Conda or uv
. The uv
method is recommended for its speed and efficient dependency management.
Method 1: Using Conda
Install Dependencies
Install the required Python packages:
pip install -r requirements.txt
Clone the Repository
Clone the Open Manus GitHub repository:
git clone https://github.com/mannaandpoem/OpenManus.git
cd OpenManus
Create a Conda Environment
Open your terminal and run:
conda create -n open_manus python=3.12
conda activate open_manus
Method 2: Using uv
(Recommended)
Install Dependencies
Use uv
to install dependencies:
uv pip install -r requirements.txt
Create a Virtual Environment
Set up and activate a virtual environment:
uv venv
source .venv/bin/activate # For macOS/Unix systems.
Clone the Repository
Similar to the Conda method:
git clone https://github.com/mannaandpoem/OpenManus.git
cd OpenManus
Install uv
Download and install uv
, a fast Python package installer:
curl -LsSf https://astral.sh/uv/install.sh | sh
4. Configuration of Open Manus
After installation, configure Open Manus to connect it with your preferred LLM API.
Steps to Configure
- Save and close the file.
Edit the config.toml
file using a text editor (e.g., nano
, vim
, or Visual Studio Code):
[llm]
model = "gpt-4o"
base_url = "https://api.openai.com/v1"
api_key = "sk-..." # Replace with your actual API key.
max_tokens = 4096
temperature = 0.0
[llm.vision]
model = "gpt-4o"
base_url = "https://api.openai.com/v1"
api_key = "sk-..." # Replace with your actual API key.
Copy the example configuration file:
cp config.example.toml config.toml
Navigate to the config
directory in the project folder:
cd config
5. Running Open Manus
Once configured, you can start using Open Manus:
Basic Usage
Run the main script from the terminal:
python main.py
You can now interact with Open Manus via terminal prompts.
Advanced Usage
For experimental features, use:
python run_flow.py
6. Troubleshooting Common Issues
Here are solutions to some common problems encountered during installation and usage:
Issue: Dependency Conflicts
- Ensure you are using Python 3.12 or higher.
- Recreate the virtual environment if necessary.
Issue: API Key Errors
- Double-check that your API key is correctly entered in
config.toml
. - Ensure that your API key has sufficient permissions.
Issue: Browser Integration Problems
If browser commands fail:
- Reconfigure browser settings in
config.toml
.
Ensure Playwright is installed:
playwright install
