Installation

Dependencies

Binary wheels should be available for most systems. If one is not available for your operating system, you will need a C compiler installed.

Install from github

Use this if you want the current code and/or if you don’t want to install it into the python path but just have a local version.

1. Clone or download the git repository:

   git clone https://github.com/jbailinua/gravhopper.git
   

2. Go into the gravhopper directory and build the code:

   cd gravhopper
   python setup.py build_ext --inplace
   

3. Copy the gravhopper subdirectory to wherever you want to use it.
