python坑之编译安装python

 

坑：

　　（1）运行django项目时报错：缺少sqlite3，下面编译迁需要先安装sqlite3

django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named '_sqlite3'

 

1.安装Python依赖包：

yum install libffi-devel zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite sqlite-devel readline-devel tk-devel gcc make -y

2.编译安装python

./configure --prefix=/usr/local/python2.7
# python3.11
./configure --prefix=/usr/local/python3.11 --with-openssl=/usr/local/openssl/


make
make install

3.编译安装 setuptools-41.0.1.zip    pip-19.1.1.tar.gz

解压
编译：/usr/local/python2.7/bin/python setup.py build
安装：/usr/local/python2.7/bin/python setup.py install

4.配置环境变量

vim /etc/profile
#加入以下内容

PATH=/usr/local/python2.7/bin:$PATH

#使用pip安装django后再加入
PATH=/usr/local/python2.7/lib/python2.7/site-packages/django/bin:$PATH

5.创建软连接

先重命名/usr/bin/xxx
mv /usr/bin/python /usr/bin/python2.6.bak
mv /usr/bin/pip /usr/bin/pip2.bak

ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
ln -s /usr/local/python2.7/bin/pip2.7 /usr/bin/pip

6.修改yum

which yum

vim /usr/bin/yum

#!/usr/bin/python2.6
