spyder: WPy32-3880 Spyder 5.0.5 missing dependency rtree>=0.9.7 : none (NOK)

The problem is in rtree, but there is a workaround.

• Find the location of "spatialindex_c-64.dll".
• In my case it was in "%USERPROFILE%\Anaconda3\pkgs\libspatialindex-1.9.3-h6c2663c_0\Library\bin".
• Create a System Environment Variable called "SPATIALINDEX_C_LIBRARY" pointing to the path of that directory.
• Restart Spyder.

My solution was, copy spatialindex_c-64.dll and paste into folder rtree. I use miniconda 3, and spyder for windows…

Hey @cnsltnt51, thanks for reporting. I have one question for you: how did you install Spyder?

I am having this problem as well, just attempted to update Spyder via

conda install spyder=5.0.5

on a fresh install of Anaconda.

The problem is in rtree, but there is a workaround.

• Find the location of "spatialindex_c-64.dll".
• In my case it was in "%USERPROFILE%\Anaconda3\pkgs\libspatialindex-1.9.3-h6c2663c_0\Library\bin".
• Create a System Environment Variable called "SPATIALINDEX_C_LIBRARY" pointing to the path of that directory.
• Restart Spyder.

This workaround worked for me with Spyder 5.1.5.

Did you restart after setting the environment variable? If that variable is set correctly, rtree should not raise that error. Also, try creating a new conda environment. In my testing, this error only occurred in the conda (base) environment.
