Linux下面安装python 的常见报错解决方法

1、升级完Python ，报No module named yum Please install a package which provides this module, or。。。。这个错误

解决方法：

# vi /usr/bin/yum

#!/usr/bin/python2.6     改成老版本的python

2、安装python辅助工具 setuptools报错，报File "/usr/local/python2.7.12/lib/python2.7/zipfile.py", line 736, in __init__
    "Compression requires the (missing) zlib module"
RuntimeError: Compression requires the (missing) zlib module。。。。这个错误

解决方法： 出现这个问题的原因是由于安装Python的时候没有进行依赖包的检查。所有首先，安装zlib

$wget http://zlib.net/zlib-1.2.8.tar.gz
$tar -xvzf zlib-1.2.8.tar.gz
$cd zlib-1.2.8.tar.gz
$./configure
$make
$sudo make install

安装完成以后，重新安装Python

cd Python-2.7.12
./configure --prefix=/usr/local/python2.7.12
make && make install

再次安装setuptools，运行sudo python setup.py install

结果如下：

copying setuptools.egg-info/top_level.txt -> build/bdist.linux-x86_64/egg/EGG-INFO
creating 'dist/setuptools-1.4.2-py2.7.egg' and adding 'build/bdist.linux-x86_64/egg' to it
removing 'build/bdist.linux-x86_64/egg' (and everything under it)
