关键字:python,python3,ssl,安装,pip

1. openssl的下载与安装

python 3若无或未指定openssl,则会报错“pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.”

wget https://www.openssl.org/source/openssl-1.1.1-pre9.tar.gz
tar xzf openssl-1.1.1-pre9.tar.gz
cd openssl-1.1.1-pre9/
./config shared --prefix=/home/python/python36/SSL && make && make install

2. python环境的准备与安装

wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
tar -xzf Python-3.6.6.tgz
cd Python-3.6.6/
export LDFLAGS="-L/home/python/python36/SSL/lib/"
export LD_LIBRARY_PATH="/home/python/python36/SSL/lib/"
export CPPFLAGS="-I/home/python/python36/SSL/include -I/home/python/python36/SSL/include/openssl"
./configure --prefix=/home/python/python36/ && make && make install

3. 优化环境配置

3.1 修改.bash_profile,添加如下内容

#
## ENV Settings for python366
#
export LDFLAGS="-L/home/python/python36/SSL/lib/"
export LD_LIBRARY_PATH="/home/python/python36/SSL/lib/"
export CPPFLAGS="-I/home/python/python36/SSL/include -I/home/python/python36/SSL/include/openssl"
PYHOME=/home/python/python36/bin
export PATH=$PYHOME:$PATH

3.2 建立软连接并使变量生效

cd /home/python/python36/bin
ln -s pip3 pip
ln -s python3.6 python
source ~/.bash_profile

4. 验证环境正确安装

pip install --upgrade pip
pip install virtualenv
pip list
显示结果如下:
Package Version
---------- -------
pip 18.0
setuptools 39.0.1
virtualenv 16.0.0
