Getting "IOError: [Errno 13] Permission denied:.." when importing pandas.DataFrame
提问by kave
I am getting
我正进入（状态
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
当我尝试导入熊猫时。我不明白为什么。在 python3 控制台中导入熊猫工作得很好。代码的执行也是用 Python3 完成的
start_simulation.py
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:
LiteForexHandler.py 的开始：
import sqlite3 as lite
from pandas import DataFrame
from DataHandler import DataHandler
import logging as log
from collections import defaultdict
...
And, finally the Traceback
最后，回溯

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.
这是 python-dateutil 的一个已知问题，其中 pypi 包中的权限设置不正确：https://bugs.launchpad.net/dateutil/+bug/1243202 。这不是 pip 的问题，因为 pip 规范了权限，但是如果您以不同的方式安装它，您可能会遇到问题。
The easy solution is to run
简单的解决方案是运行
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.
以及在 dist-packages 目录中遇到此问题的任何其他文件上的相同命令。

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.
我只是在我的机器上遇到了类似的问题。Pip 没有让我安装任何东西，因为没有任何东西可以写入我的 site-packages 目录。不喜欢这个，但我跑了sudo chown -R $USER /Library/Python/2.7/site-packages/，现在 Pip 写入我的 site-packages 目录没有问题。

In my case:
就我而言：
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:
一般来说：
sudo chmod o+r [XXX]
where XXX is the file it is pointing to.
其中 XXX 是它指向的文件。
