CentOs 6安装python2.7.13及异常解决

1、CentOS安装Python的依赖包

yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

2、下载Python2.7.13的源码包并编译

wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
tar xf Python-2.7.13.tgz
cd Python-2.7.13
./configure --prefix=/usr/local
make
make install

可能出现的异常:

1. import sqlite3时抛出异常：ModuleNotFoundError: No module named '_sqlite3'

2. 没有安装pip

1.import sqlite3时抛出异常：ModuleNotFoundError: No module named '_sqlite3'

yum install --installroot=/usr/local/ sqlite3

修改python setup.py文件

cd Python-2.7.13
vi ./setup.py

sqlite_inc_paths = [ '/usr/include',
                             '/usr/local/sqlite3/include', #增加该部分内容
                             '/usr/include/sqlite',
                             '/usr/include/sqlite3',
                             '/usr/local/include',
                             '/usr/local/include/sqlite',
                             '/usr/local/include/sqlite3',]

然后重新编译就可以了。

2.没有安装pip

# 安装Pip
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz
tar -vxf setuptools-1.4.2.tar.gz 
cd setuptools-1.4.2
python2.7 setup.py install  # 若系统默认的为python2.7可以直接使用python
easy_install-2.7 pip
