当我得到入门 “IO错误：[错误13]许可被拒绝：..” 进口pandas.DataFrame
IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/top_level.txt'
当我试图导入大熊猫。我不明白为什么。在python3控制台中导入熊猫工作得很好。代码的执行与Python3做得太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()`
开始的
LiteForexHandler.py：
import sqlite3 as lite
from pandas import DataFrame
from DataHandler import DataHandler
import logging as log
from collections import defaultdict
...
而且，最后回溯

你可以尝试的一件事是将每个包安装在virtualenv中。出于某种原因，一个模块试图访问'/ usr/local/lib'中的一个文件，这是因为您没有以超级用户的身份运行脚本。 – elbear
我推荐anaconda安装熊猫，你可以安装不带sudo的熊猫。 –
我从python3-pandas软件包中的ubuntu存储库安装了熊猫...应该不是最好的方法吗？ – kave
