Missing dependancies of rtree
Please execute the following command if you are using Anaconda:
conda install -c conda-forge rtree=0.9.3
Though I had rtree version 0.9.7, Spyder couldn't detect it. So I had to manually downgrade it.
Came here with same problem, I don't use conda and could not install libspatialindex with pipenv:
# macOS Mojave 10.14.5
# python 3.7.4 (via pyenv)
Error: Command "python setup.py egg_info" failed with error code 1 in /var/folders/r7/2sx1wsvx0gj5x43wkmymg61w0000gq/T/tmpn09357tzbuild/rtree/
Found solution — install spatialindex via Homebrew:
brew install spatialindex
Then pipenv install rtree succeeded and now geopandas works smoothly
Hope it'll help
I encountered this same problem and tried to all the solutions shown in this page. But failed.
Finally, i find the solution that is...
- run the anaconda-navigator at the base.
- Click and activate the environment what you want to fix
- At the right search bar, type the 'rtree' and you can see the installed 'rtree' which has the version at 0.9.3 maybe.
- Click the small green checkbox on the left of 'rtree' in Name tab then put your mouse cursor over the 'mask for specific installation' menu.
- Click version '0.8.3' to downgrade via the anaconda-navigator.
after then, i executed spyder and the error message disappeared.
It looks like Rtree requires libspatialindex (https://libspatialindex.org) which is not automatically installed. It seems some devs are aware of the problem and working on a fix:
