git clone https://github.com/Ultimaker/Cura.git 
cd Cura

3. Initialize the Virtual Python Development Environment

Install the dependencies for the development environment and initialize a virtual Python environment. Execute the following command in the root directory of the Cura repository.

# optional for a specific version: conan install . cura/<version>@<user>/<channel> --build=missing --update
conan install . --build=missing --update -o cura:devtools=True -g VirtualPythonEnv

If you use PyCharm, append -g PyCharmRunEnv. This will create a run/debug/test configurations. You must click Add Configuration..., and click Apply for these to be displayed.

If you get an error like ERROR: while executing system_requirements(): Aborted due to CONAN_SYSREQUIRES_MODE=verify. Some system packages need to be installed you need to install the required system packages.

4. Activate the Virtual Python Environment

Activate the virtual environment by executing the following command in the root directory of the Cura repository.

# For Linux/MacOS
source venv/bin/activate

# For Windows (Powershell)
.\venv\Scripts\activate.ps1
