2020-07-02 离线安装python 2.7的requests模块

requests 是 Python 的一个 HTTP 客户端库，跟 urllib，urllib2 类似，不过 requests 的优势在于使用简单，相同一个功能，用 requests 实现起来代码量要少很多。毕竟官方文档都很直白的说：

python 的标准库 urllib2 提供了大部分需要的 HTTP 功能，但是 API 太逆天了，一个简单的功能就需要一大堆代码。

所以，使用 requests 方便的多。

参考pip在线安装

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

随后解压并准备安装

错误的离线安装命令

F:\Python27\python.exe F:\Programs\requests-2.24.0\requests-2.24.0\setup.py install

报错`readme.md`找不到

G:\Projects\github\hmac-auth-java-sdk\hmac-auth\jars>F:\Python27\python.exe F:\Programs\requests-2.24.0\requests-2.24.0\setup.py install
Traceback (most recent call last):

    with open('README.md', 'r', 'utf-8') as f:
  File "F:\Python27\lib\codecs.py", line 898, in open
    file = __builtin__.open(filename, mode, buffering)
IOError: [Errno 2] No such file or directory: 'README.md'

意识到可能是使用了相对路劲去找上述问价，导致找不到，所以打算进入到`setup.py`所在目录
