Unable to install cartopy using pip

[drorata]

[Cross posting from http://stackoverflow.com/questions/28307950/install-cratopy-using-pip-on-mac-os-and-macports]

I am trying to install cartopy on OS X 10.10 (Yosemite). My python is installed using macports and when I run:

sudo pip install cartopy

I get the following error:

/usr/bin/clang -Wno-unused-result -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -pipe -Os -I/opt/local/Library/Frameworks/Python.framework/Versions/3.4/include -I./lib/cartopy -I/opt/local/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m -c lib/cartopy/trace.cpp -o build/temp.macosx-10.10-x86_64-3.4/lib/cartopy/trace.o

lib/cartopy/trace.cpp:236:10: fatal error: 'geos_c.h' file not found

#include "geos_c.h"

         ^

1 error generated.

error: command '/usr/bin/clang' failed with exit status 1

----------------------------------------
Command "/opt/local/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4 -c "import setuptools, tokenize;__file__='/tmp/pip-build-hwrcv0a1/cartopy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-ytar95bq-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-hwrcv0a1/cartopy

Note that I installed the dependencies as noted here and geos_c.h can be found in /opt/local/include. It seems like pip fails to find this dependency in the macports tree.

Did anyone experienced this kind of problem? How can I fix it?

The code which generates this error is setup at https://github.com/SciTools/cartopy/blob/master/setup.py#L169.

Though I've never tried it, it may be possible to pass the LIBDIR and INCLUDEDIR values at setup.py time:

LIBDIR="/opt/local/lib" INCLUDEDIR="/opt/local/include" python setup.py install

If that fails, perhaps http://stackoverflow.com/questions/18783390/python-pip-specify-a-library-directory-and-an-include-directory will be helpful.

As a heads up, the python3 support is still a little under tested - there is an outstanding PR to get py3 travis-ci testing which will give us much more confidence about maintaining compatibility with py2 and py3 simultaneously.

[drorata]

Sounds interesting but I don't know how to pass arguments to the pip install. Can I use pip and the variables you mentioned?

[QuLogic]

@drorata Do you have a geos-config that outputs the correct path?

[drorata]

@QuLogic I have this binary installed (/opt/local/bin/geos-config). What should I do with it?

[QuLogic]

I've opened a PR (#577) which should automatically determine paths using the geos-config binary. If you're able, maybe you can try installing via that branch. I'm pushing to get this applied before 0.12.0 it released and certainly some confirmation that it will work in cases such as yours will help the argument.

If you are unable to do that, that's fine. I don't know if @pelson's suggestion would work otherwise.

[QuLogic]

BTW, you don't need to (explicitly) clone the repo to test; you can install directly via pip install git+https://github.com/QuLogic/cartopy.git@requirements, though I think it still requires you to have git installed.

[drorata]

I just tried your suggestion, but it did not work:

Command "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python -c "import setuptools, tokenize;__file__='/tmp/pip-iNPm2B-build/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-zKQV6R-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-iNPm2B-build

[QuLogic]

You need to post the beginning of the error, not the end.

[QuLogic]

@drorata ping?

[drorata]

@QuLogic sorry --- I'm very busy. I'll post the complete error as soon as possible.

[pelson]

Found what looks like a solution. A ``.pydistutils.cfg` file may be an option. See http://stackoverflow.com/questions/15725869/pass-build-ext-options-to-pip-install.

I was getting the same error. I resolved it by upgrading goes from 3.5.0 to 3.6.1. On my OSX machine, I did: brew upgrade geos.

This way solved the problem in MacOS 12.6
