[GIS] installing rtree on windows 64 bits

oserrorrtree

I am using windows10 64 bits, my os.name is 'nt', I used pip to install but its complaining about the spatialindex_c.dll

 File "C:\Users\Bachir\AppData\Local\Temp\pip-build-td64lrth\rtree\rtree\core.py", line 101, in <module>
   raise OSError("could not find or load spatialindex_c.dll")
 OSError: could not find or load spatialindex_c.dll

I downloaded rtree-0.8.2 and then run python setup.py install and i have the same message 

PS C:\Users\Bachir\documents\Python Scripts\Rtree-0.8.2> python setup.py install
Traceback (most recent call last):
File "setup.py", line 4, in <module>

I donwloaded the spatialindex dll files ' libspatialindex-1.8.1-win-msvc-2010-x64-x32.zip ' . this file contain both 32 and 64 bits , unzip and put in the installation folder, when installing using python setuo.py install it still complaining about the spatialindex dll file

Best Answer

Please, look at How can I install pyproj into arcpy?

1) the RTree module needs to be compiled with a version of libspatialindex installed in the system (your computer) and not simply adding spatialindex dll after
2) Windows has no compiler by default as in Linux or Mac OS X therefore you cannot install RTree with pip or setup.py install
3) in the Python Package Index page of RTree, bellow Download there is specified

Windows binaries http://www.lfd.uci.edu/~gohlke/pythonlibs/#rtree

The files are Rtree-0.8.2-cp27-none-win32.whl and Rtree-0.8.2-cp27-none-win_amd64.whl

To install a whl file, download the file and

pip install Rtree-0.8.2-cp27-none-....whl (32 or 64)
