首先可以去django官网查一下合适的版本(支持python 2.7 和python3.x)
安装方法参考官网，Option 2中 development version是非稳定版本，可以下载tar.gz包安装
Python环境(3.7.1)
方法一：使用pip安装("==" 后写django版本号)
pip install Django==2.1.4
安装成功后可以使用命令 python -m django --version 查看版本，也可以进入python交互环境执行 import django确认无报错。
Python 3.7.1 (default, Dec 15 2018, 19:57:31)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> import django
>>>
方法二：使用源码安装
首先，把官网下载的tar.gz上传至服务器并解压缩
# tar -xzvf Django-2.1.4.tar.gz
然后进入Django解压后的路径，里面有setup.py，执行python setup.py install
# ls
Django-2.1.4 Django-2.1.4.tar.gz
# cd Django-2.1.4
# python setup.py install
如果顺利的话，安装完成。但是，遇到了两个问题
问题1：
[root@xxx Django-2.1.4]# python setup.py install
Traceback (most recent call last):
File "setup.py", line 32, in
""".format(*(REQUIRED_PYTHON + CURRENT_PYTHON)))
ValueError: zero length field name in format
[root@xoam Django-2.1.4]# python setup.py help
Traceback (most recent call last):
File "setup.py", line 32, in
""".format(*(REQUIRED_PYTHON + CURRENT_PYTHON)))
ValueError: zero length field name in format
原因：上网查了一下有博主进一步分析得出是python版本的问题。检查了一下自己的环境除了python3.7还妆了python2.6，而python2.6是不支持django的。
解决：执行python命令带上python3全路径，例如
[root@xxx Django-2.1.4]# /opt/python3/Python-3.7.1/python setup.py install
或者使用python3(没有试，应该可以)
[root@xxx Django-2.1.4]# python3 setup.py install
以上报错解决后，安装过程遇到了第二个报错
问题2：
...

Searching for pytz
Reading https://pypi.python.org/simple/pytz/

Couldn't find index page for 'pytz' (maybe misspelled?)
Scanning index of all packages (this may take a while)

Download error on https://pypi.python.org/simple/: unknown url type: https -- Some packages may not be found!

于是去python官网下载pytz安装(同样解压后去pytz路径执行python setup.py install)
再去安装Django，成功~
