1）已从pypi官网下载到安装包（.whl文件）即line_profiler-3.3.1-cp35-cp35m-manylinux1_x86_64.whl
出现line_profiler-3.3.1-cp35-cp35m-manylinux1_x86_64.whl is not a supported wheel on this platform问题
顺便一提：pip3 install line_profiler-3.3.1-cp35-abi3-manylinux1_x86_64.whl (将原安装包的文件名改一下)——****该方法行不通****
建议直接选用下面方法
2）直接pip install安装
出现Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-3MSooA/line-profiler/问题
解决方法：pip3 install line_profiler
如图所示
