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

问题:

I am getting

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 am trying to import pandas. I don't see why. Importing pandas in the python3 console works just fine. Execution of the code is done with Python3 too

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 the Traceback

回答1:

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

The easy 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 on any other file you encounter with this problem in the dist-packages directory.

回答2:

I was just having similar issues on my machine. Pip wasn't letting my install anything because nothing could be written to my site-packages directory. Not in love with this but I ran sudo chown -R $USER /Library/Python/2.7/site-packages/ and now Pip has no problem writing to my site-packages directory.

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 

In general:

sudo chmod o+r [XXX] 

where XXX is the file it is pointing to.
