关于Python 2.6/2.7软件包安装的困惑
我有一台安装了 Redhat 6 的服务器，最初安装的是 Python 2.6（通过 /usr/bin/python 调用）。几天前我安装了 Python 2.7.10（通过 /usr/local/bin/python 或者简单地使用 python 调用）。\n今天早些时候，我使用 sudo easy_install pip 命令安装了 pip。通过 whereis pip 命令可以得到结果 pip: /usr/bin/pip2.6 /usr/bin/pip。\n然后我想要通过运行 sudo pip install pandas 命令安装 pandas 包。它报告安装成功，但是无论对于哪个版本的 python，import pandas 都会产生错误：\nmyPrompt 733] python\nPython 2.7.10 (default, Jul 16 2015, 14:41:11) \n[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2\nType \"help\", \"copyright\", \"credits\" or \"license\" for more information.\n>>> import pandas\nTraceback (most recent call last):\n File \"\", line 1, in \nImportError: No module named pandas\n>>> exit()\nmyPrompt 734] /usr/bin/python\nPython 2.6.6 (r266:84292, Nov 21 2013, 10:50:32) \n[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2\nType \"help\", \"copyright\", \"credits\" or \"license\" for more information.\n>>> import pandas\nTraceback (most recent call last):\n File \"\", line 1, in \nImportError: No module named pandas\n>>> exit()\nmyPrompt 735] pip install pandas\nTraceback (most recent call last):\n File \"/usr/bin/pip\", line 5, in \n from pkg_resources import load_entry_point\n File \"/usr/lib/python2.6/site-packages/pkg_resources.py\", line 2655, in \n working_set.require(__requires__)\n File \"/usr/lib/python2.6/site-packages/pkg_resources.py\", line 648, in require\n needed = self.resolve(parse_requirements(requirements))\n File \"/usr/lib/python2.6/site-packages/pkg_resources.py\", line 546, in resolve\n raise DistributionNotFound(req)\npkg_resources.DistributionNotFound: pip==7.1.0\nmyPrompt 736] sudo pip install pandas\nEnter PASSCODE:\nRequirement already satisfied (use --upgrade to upgrade): pandas in /usr/lib64/python2.6/site-packages\nRequirement already satisfied (use --upgrade to upgrade): python-dateutil in /usr/lib/python2.6/site-packages (from pandas)\nRequirement already satisfied (use --upgrade to upgrade): pytz>=2011k in /usr/lib/python2.6/site-packages (from pandas)\nRequirement already satisfied (use --upgrade to upgrade): numpy>=1.7.0 in /usr/lib64/python2.6/site-packages (from pandas)\nRequirement already satisfied (use --upgrade to upgrade): six>=1.5 in /usr/lib/python2.6/site-packages (from python-dateutil->pandas)\n\n所以 pip 的配置和包的安装存在某种混淆。我应该如何解决这个问题？我需要重新安装 pip 吗？\n最终，我不关心 Python 2.6，只想使用 Python 2.7。\n谢谢
