标签（空格分隔）： 未分类
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 makecache2.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/python3.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 /.configuremakemake 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) ALL6.遇到ImportError: cannot import name HTTPSHandleryum install openssl openssl-devel -y
之后，再重新安装Python即可。/.configuremakemake 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Lib\mimetypes.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('\r\n', '\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):

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
