最近想要看看Django，以前安装过python，现在想按照教程来学习，结果发现在安装Django包（命令：pip install django）时候出问题了，说我的pip版本低建议更新一下：
C:\Users\me>pip install django
Collecting django
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x000001A8F0612898>, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/django/

You are using pip version 10.0.1, however version 20.0.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
查看pip版本
C:\Users\me>pip --version
pip 10.0.1 from c:\program files\python36\lib\site-packages\pip (python 3.6)
目前版本是20.0.2，的确有点低，就按照给出的命令（python -m pip install --upgrade pip）试试：
C:\Users\me>python -m pip install --upgrade pip

发现不行，根据提示说明，是需要在命令汇总加“--user”，加上试试，但是不知道从哪加，百度一手然后试试

提示成功了，再pip --version看看
C:\Users\me>pip --version
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.
pip 20.0.2 from C:\Users\me\AppData\Roaming\Python\Python36\site-packages\pip (python 3.6)
ok了，开始Django
