1.系统
666@66:/proc$ cat /proc/version
Linux version 4.4.0-128-generic (buildd@lgw01-amd64-055) (gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.4) )
2.安装
系统默认安装了python2.7，这里演示安装python3.6。
1. 从python官网下载python3.6.5 Source release版本

2. 解压源码安装
- 解压得到Python-3.6.5文件夹
kjs@42:~/下载$ xz -d Python-3.6.5.tar.xz
kjs@42:~/下载$ tar -xvf Python-3.6.5.tar
- 进入文件夹，进行编译（指定目标文件夹，pip 的时候可能缺少 ssl，所以这里配置的时候加上）
kjs@42:~/下载/Python-3.6.5$ ./configure --prefix=/usr/local/python-3.6 --with -ssl
- 编译及安装
kjs@42:~/下载/Python-3.6.5$ make
kjs@42:~/下载/Python-3.6.5$ sudo make install
3.检查python pip版本 并创建软链接到 /usr/bin下
- 检查版本
kjs@42:~/下载/Python-3.6.5$ cd /usr/local/python-3.6/bin
kjs@42:/usr/local/python-3.6/bin$ ./python3
Python 3.6.5 (default, Jul 5 2018, 14:32:19)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
kjs@42:/usr/local/python-3.6/bin$ ./pip3 -V
pip 10.0.1 from /usr/local/python-3.6/lib/python3.6/site-packages/pip (python 3.6)
kjs@42:/usr/local/python-3.6/bin$
- 创建软链接
kjs@42:/usr/local/python-3.6/bin$ sudo ln -s python3 /usr/bin/python3
kjs@42:/usr/local/python-3.6/bin$ sudo ln -s pip3 /usr/bin/pip3
- 检查
kjs@42:~$ python3
Python 3.6.5 (default, Jul 5 2018, 14:32:19)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()
kjs@42:~$ pip3 -V
pip 10.0.1 from /usr/local/python-3.6/lib/python3.6/site-packages/pip (python 3.6)
kjs@42:~$
版本没有问题，执行pip3 install 试试

问题原因：python3.6.5不支持lsb_release -a命令
解决办法：系统自带的python3.4支持该命令
修改 lsb_release 文件
kjs@42:~$ vim /usr/bin/lsb_release
将第一行的 python3 改成相应的python版本
1 #! /usr/bin/python3.4.4.4.4 -Es
2
3 # lsb_release command for Debian

执行 pip3 install request 即可成功
