Answer 1

User DYZ provided the correct answer in the comments.

You need to install spatialindex.

This question should be set to answered so it is not misleading

Answer 2

If you are using MacOS, it's as simple as follow:

brew install spatialindex
pip install rtree

If you are working on linux environment you have to build this from source:

1. Install spatialindex

   curl -L https://github.com/libspatialindex/libspatialindex/archive/1.8.5.tar.gz | tar xz
   cd libspatialindex-1.8.5/
   ./autogen.sh
   ./configure
   make
   sudo make install
   sudo ldconfig
   

2. install rtree: pip install rtree

Answer 3

I had the same issue while working in Linux Subsystem at Windows 10 (speaking about this). What helped was installing the version for developers using apt. Namely:

sudo apt install libspatialindex-dev did the job.

I did not need to work with make.

edit: Nice to see my answer has been upvoted so many times; in the time of writing it, however, this was not the most popular answer and it was preceeded by the other answers that suggested using make. This is why I am referring to this command; and I think the other answers are worth reading anyway.

Linux installation steps for Docker users:

RUN apt-get update
RUN apt-get install -y --fix-missing curl autoconf libtool automake
RUN curl -L https://github.com/libspatialindex/libspatialindex/archive/1.8.5.tar.gz | tar -xz
RUN cd libspatialindex-1.8.5 && ./autogen.sh && ./configure && make && make install && ldconfig
