定位到 C:ProgramsPythonPython35Scripts>
执行 pip --version 命令，查看pip版本

PS C:ProgramsPythonPython35Scripts> pip --version

执行 pip install -U pip 命令，更新pip到最新版本

PS C:ProgramsPythonPython35Scripts> pip install -U pip

再次执行 pip --version 命令，查看pip版本是否已经更新

PS C:ProgramsPythonPython35Scripts> pip --version

jupyter安装

执行 python -m pip install jupyter 命令，进行安装，会下载很多包，

PS C:ProgramsPythonPython35Scripts> python -m pip install jupyter

注意：假如出现这个错误 ERROR: Could not install packages due to an EnvironmentError: raw write() returned invalid length 2 (should have been between 0 and 1)

再次执行 python -m pip install jupyter 命令，会在上一次的基础上继续安装，

PS C:ProgramsPythonPython35Scripts> python -m pip install jupyter

启动jupyter

PS C:ProgramsPythonPython35Scripts> jupyter notebook

会打开浏览器，进到这个地址 http://localhost:8888/tree

右侧 new 下拉选项中选择python3 选项，会进到一个新的笔记页， http://localhost:8888/notebooks/Untitled.ipynb?kernel_name=python3

此时就可以进行python 编码了
