Hi,
I am a Mac user (EI Capitan), trying to run PyRoot in Spyder:
github.com/spyder-ide/spyder/releases
I installed root 6, python 2.7.10, and the corresponding spyder release;
I could open root in my terminal, and open python, import ROOT:
[code]Python 2.7.10 (v2.7.10:15c95b7d81dc, May 23 2015, 09:33:12)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type “help”, “copyright”, “credits” or “license” for more information.
import ROOT[/code]
It works fine.
However, if I try to run this under Spyder:
>>> import ROOT
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/renormalization/root/lib/ROOT.py", line 24, in <module>
import cppyy
File "/Users/renormalization/root/lib/cppyy.py", line 60, in <module>
import libPyROOT as _backend
ImportError: dlopen(/Users/renormalization/root/lib/libPyROOT.so, 2): Library not loaded: @rpath/libCore.so
Referenced from: /Users/renormalization/root/lib/libPyROOT.so
Reason: image not found
Previously, I get the instruction to specify the LD_LIBRARY_PATH; however, if I run this code:
import os, sys
sys.path.append('/Users/renormalization/root/')
os.environ['ROOTSYS'] = '/Users/renormalization/root'
os.environ['LD_LIBRARY_PATH'] = os.path.join(os.environ['ROOTSYS'], 'lib') + os.pathsep + os.environ['LD_LIBRARY_PATH']
os.execv(sys.executable, sys.argv)
import ROOT
Then I get this output:
>>> runfile('/Users/renormalization/.spyder2/temp.py', wdir='/Users/renormalization/.spyder2')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

File "UserDict.pyc", line 23, in __getitem__
KeyError: 'LD_LIBRARY_PATH'
Could you help me with this? Much appreciated!
Best Regards,
Tony
