Getting "IOError: [Errno 13] Permission denied: .." when importing pandas.DataFrame

Question

I get

IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/top_level.txt' 

when i try to import pandas. I do not understand why. Importing pandas into the python3 console works fine. Code execution is also done using Python3

start_simulation.py

 from Market import Market from TestingAlgorithm import TestingAlgorithm from LiteForexHandler import LiteForexHandler from Broker import Broker from Portfolio import Portfolio market = Market('./simulations/', 'test', TestingAlgortihm, LiteForexHandler, Broker, Portfolio) market.run()` 

Start of LiteForexHandler.py :

 import sqlite3 as lite from pandas import DataFrame from DataHandler import DataHandler import logging as log from collections import defaultdict ... 

And finally, Traceback

 Traceback (most recent call last): File "start_simulation.py", line 3, in <module> from LiteForexHandler import LiteForexHandler File "/home/ioan/Dokumente/finance/stocker/LiteForexHandler.py", line 2, in <module> from pandas import DataFrame File "/usr/local/lib/python2.7/dist-packages/pandas-0.13.1_501_g4c3b9e5-py2.7-linux-x86_64.egg/pandas/__init__.py", line 38, in <module> import pandas.core.config_init File "/usr/local/lib/python2.7/dist-packages/pandas-0.13.1_501_g4c3b9e5-py2.7-linux-x86_64.egg/pandas/core/config_init.py", line 17, in <module> from pandas.core.format import detect_console_encoding File "/usr/local/lib/python2.7/dist-packages/pandas-0.13.1_501_g4c3b9e5-py2.7-linux-x86_64.egg/pandas/core/format.py", line 9, in <module> from pandas.core.index import Index, MultiIndex, _ensure_index File "/usr/local/lib/python2.7/dist-packages/pandas-0.13.1_501_g4c3b9e5-py2.7-linux-x86_64.egg/pandas/core/index.py", line 11, in <module> import pandas.index as _index File "index.pyx", line 34, in init pandas.index (pandas/index.c:15559) File "/usr/local/lib/python2.7/dist-packages/pytz-2014.2-py2.7.egg/pytz/__init__.py", line 29, in <module> from pkg_resources import resource_stream File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2823, in <module> add_activation_listener(lambda dist: dist.activate()) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 710, in subscribe callback(dist) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2823, in <lambda> add_activation_listener(lambda dist: dist.activate()) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2255, in activate self.insert_on(path) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2362, in insert_on self.check_version_conflict() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2401, in check_version_conflict for modname in self._get_metadata('top_level.txt'): File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2249, in _get_metadata for line in self.get_metadata_lines(name): File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 1219, in get_metadata_lines return yield_lines(self.get_metadata(name)) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 1211, in get_metadata return self._get(self._fn(self.egg_info,name)) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 1326, in _get stream = open(path, 'rb') IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/top_level.txt' 

Answer 1

This is a known issue with python-dateutil where permissions are not set correctly in the pypi package: https://bugs.launchpad.net/dateutil/+bug/1243202 . This is not a problem with pip because pip normalizes permissions, but if you install it differently, you may run into problems.

A simple solution is to run

 sudo chmod o+r /usr/local/lib/python2.7/dist-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/top_level.txt 

and the same command in any other file you encounter this problem in the dist-packages directory.

Answer 2

I had similar problems on my machine. Pip did not allow my installation to do anything because nothing could be written to my site directory. I didn’t fall in love with this, but I ran sudo chown -R $USER /Library/Python/2.7/site-packages/ , and now Pip has no problem writing package sites to my directory.

Answer 3

In my case:

 sudo chmod o+r /usr/local/lib/python2.7/dist-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/top_level.txt 

Generally:

 sudo chmod o+r [XXX] 

where XXX is the file it points to.
