linux环境搭配和处理

安装python3.5

安装python3.5可能使用的依赖

::

apt-get install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

到python官网找到下载路径, 用wget下载

::

wget https://www.python.org/ftp/python/3.5.1/Python-3.5.1.tgz

#解压
tar -zxvf Python-3.5.1.tgz


cd Python-3.5.1               
./configure --enable-shared --prefix=/usr/local
make && make altinstall

搭建python3开发环境

1.安装virtualenv

::

pip install virtualenv

创建虚拟环境

::

virtualenv -p /usr/local/bin/python3.4 py34env

激活虚拟环境

::

source py34env/bin/activate

在虚拟环境中安装ipython

::

pip install ipython

如果安装过程中提示如下错误：

Can't connect to HTTPS URL because the SSL module is not available. - skipping
请安装以下库:

::

yum install openssl-devel 

然后重新编译安装Python：

::

./configure --prefix=/usr/local &&  make && make altinstall  

在虚拟环境中启动ipython

::

ipython

退出虚拟环境

::

deactivate
