Windows 10.0.105 Pro 上的 Pip 问题

问：

Pip 应该与 Python 3.5 捆绑在一起，但它显然不在我的路径中，我没有看到它的二进制文件。

我尝试了这个解决方法：

C:\Python35>py -m pip install requests
You are using pip version 7.0.1, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting requests
  Downloading requests-2.9.1-py2.py3-none-any.whl (501kB)
    100% |################################| 503kB 561kB/s
Installing collected packages: requests
Successfully installed requests-2.9.1

看起来它很成功，但显然仍然存在一个问题：

C:\Python35>pip3 install --upgrade pip

operable program or batch file.

C:\Python35>pip install --upgrade pip
