Python常用模块安装
最近经常需要安装一些python环境的模块，每次安装后，没有记录，都要找，今天打算开个博，记录下，后续相关安装，陆续更新！1、首先要安装pip，linux下安装pip，我之前记录，详细可以参考如下链接

2、python模块安装
2.1 安装requests模块
pip install requests
报错：ImportError: cannot import name HTTPSHandler
解决办法： 重新编译安装python
wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar zxvf Python-2.7.13.tgz
cd Python-2.7.13
./configure
make
make install
2.2 安装PyQuery模块
pip install PyQuery
问题：
Requirement already satisfied (use --upgrade to upgrade): pyquery in /usr/local/lib/python2.7/site-packages
Cleaning up...
解决办法： pip install --upgrade pip
升级完成后，在次安装解决
2.3 安装MySQLdb模块
wget https://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/MySQL-python-1.2.3.tar.gz --no-check-certificate
$ tar xfz MySQL-python-1.2.3.tar.gz
$ cd MySQL-python-1.2.3
$ # edit site.cfg if necessary
$ python setup.py build
$ sudo python setup.py install # or su first
注：如果报错：error: command 'gcc' failed with exit status 1
解决办法：yum install gcc python-devel mysql-devel
