Spyder 5.2.0 (installed with Conda) complains about missing dependency: Rtree >= 0.9.7 : None (NOK)
Opened this issue · 4 comments
Using conda 4.10.3 on Windows 10 64-bit.
Installed Spyder 5.2.0 from conda-forge, and rtree 0.9.7 was downloaded and deployed automatically. So far so good. However, shortly after starting Spyder the missing dependency error pops up.
Copying the missing spatialindex_c-64.dll
to ...miniconda3\envs\<env name>\Lib\site-packages\rtree
is a suitable workaround, which suggests that the problem is with how rtree looks for the dll.
It seems to me that the root of the issue is in finder.py
. Line 58 is currently :
rt = ctypes.cdll.LoadLibrary(os.path.join(path, lib_name))
but I think it should rather read
rt = ctypes.cdll.LoadLibrary(lib_name)
In my case at least this solves the problem.

@bghadam, folks,
Line 58 is for os.name == 'nt'
, os.name == 'posix'
is farther down.
On Macos 10.14 with Miniconda3-py37_4.10.3-MacOSX-x86_64.pkg I had to
cd /opt/miniconda3/lib/python3.7/site-packages/rtree
ln -s /opt/miniconda3/lib/libspatialindex_c.6.1.1.dylib libspatialindex_c.dylib
(Imho, it would be nice if rtree wheels just worked, i.e. had the .dylib inside.
Maybe this used to work, see the comments in rtree setup.py;
the finder
approach is almost impossible to test thoroughly, so breaks easily, and does break.)
Got hit with the same issue on Windows. I can confirm my problem is that I'm using 32-bits Python 3.10, and there's no wheels published for this combination. Just like #245, I think in this case setup should just die, not pretend it has the library.
