1.修改163的yum源

使用说明

首先备份/etc/yum.repos.d/CentOS-Base.repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)

CentOS6

运行以下命令生成缓存

yum clean all  yum makecache

2.更新python从2.6.6版本为2.7

#wget http://www.python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2  #tar jxvf Python-2.7.5.tar.bz2  #cd Python-2.7.5  #./configure --prefix=/usr/local  #make && make altinstall  #mv /usr/bin/python /usr/bin/python2.6.6  #ln -s /usr/local/bin/python2.7 /usr/bin/python

3.安装pip 1）安装setuptools 解压安装遇到错误 RuntimeError: Compression requires the (missing) zlib module

yum install zlib& zilib devel

然后遇到yum因为python版本不对错误错误：

[root@localhost bin]# yum install pip  There was a problem importing one of the Python modules  required to run yum. The error leading to this problem was:       No module named yum    Please install a package which provides this module, or  verify that the module is installed correctly.    It's possible that the above module doesn't match the  current version of Python, which is:  2.7.3 (default, Jan 16 2016, 05:59:11)  [GCC 4.4.6 20120305 (Red Hat 4.4.6-4)]    If you cannot solve this problem yourself, please go to  the yum faq at:    http://yum.baseurl.org/wiki/Faq

查找yum文件,并编辑此py文件

[root@develop local]# which yum  /usr/bin/yum  [root@develop local]# vi /usr/bin/yum    将  #!/usr/bin/python  改为:  #!/usr/bin/python2.6    然后保存OK.    补充：yum基于python写的。

4.安装zlib&zlib-devel 重新编译python /.configure make make install 然后重新安装setuptools

5.遇到wangqi is not in the sudoers file.

#visudo  ## Allow root to run any commands anywhere  root    ALL=(ALL)       ALL  wangqi  ALL=(ALL)       ALL

6.遇到ImportError: cannot import name HTTPSHandler yum install openssl openssl-devel -y 之后，再重新安装Python即可。 /.configure make make install

7.pip安装完成 8.安装numpy, 9.安装pandas 出现问题： UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 32: ordinal not in range(128) 解决方法： 修改mimetypes.py文件，路径位于python的安装路径下的Libmimetypes.py文件。在import下添加如下几行：

if sys.getdefaultencoding() != 'gbk':      reload(sys)      sys.setdefaultencoding('gbk')

依然报错：

gcc: error trying to exec 'cc1plus': execvp: No such file or directory    error: command 'gcc' failed with exit status 1

尝试解决： yum -y install gcc

依然报错：

Command /usr/local/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/pandas/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('rn', 'n'), __file__, 'exec'))" install --record /tmp/pip-5RbGXm-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/pandas  Traceback (most recent call last):    File "/usr/local/bin/pip", line 9, in <module>      load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()    File "/usr/local/lib/python2.7/site-packages/pip-1.5.6-py2.7.egg/pip/__init__.py", line 185, in main      return command.main(cmd_args)    File "/usr/local/lib/python2.7/site-packages/pip-1.5.6-py2.7.egg/pip/basecommand.py", line 161, in main      text = 'n'.join(complete_log)  UnicodeDecodeError: 'gbk' codec can't decode bytes in position 97-98: illegal multibyte sequence

使用安装包直接进行安装，发现是以下问题：

gcc: error trying to exec 'cc1plus': execvp: No such file or directory  error: command 'gcc' failed with exit status 1

安装gcc-c++

[root@localhost pandas-0.17.1]# yum list gcc-c++  Loaded plugins: fastestmirror, refresh-packagekit, security  Loading mirror speeds from cached hostfile  Available Packages  gcc-c++.i686                                 4.4.7-16.el6                                  base  [root@localhost pandas-0.17.1]# yum -y install gcc-c++.i686

遇到问题

No local packages or download links found for python-dateutil  error: Could not find suitable distribution for Requirement.parse('python-dateutil')

pip install python-dateutil

终于大功告成
