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
