1、git clone https://github.com/HttpRunner/HttpRunner.git 到本地
2、查看目前正在使用的Python版本：pyenv versions，默认只有system
3、查看可以安装的Python版本
pyenv install --list
4、官方建议Python3.6版本，so，安装需要的Python版本
pyenv install 3.6.2
5、切换Python版本，将Python 3.6.2置为默认
pyenv global 3.6.2, *号代表默认版本
特别建议：
优先级关系：shell——local——global
6、启动服务 需要Flask-Script支持
iwm@bogon ~ pip install Flask-Script
zsh: command not found: pip
7、提示找不到pip命令
iwm@bogon /usr/local/Cellar sudo easy_install pip
8、安装Flask-Script失败，error: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/itsdangerous.py'
iwm@bogon /usr/local/Cellar pip install Flask-Script

9、chomd赋予权限
sudo chmod 777 /Library/Python/2.7/site-packages/
10、再次执行pip install Flask-Script
11、若第七步报如下错误，使用：pip --trusted-host pypi.python.org install Flask-Script
12、启动httprunner，提示未发现HttpRunner强依赖的 'PyUnitReport'
13、install PyUnitReport
14、install PyYAML
15、install requests
16、install pyOpenSSL
17、 hrun -V
18、cd httprunner根目录下，执行export FLASK_APP=tests/api_server.py
19、接着执行flask run
遇到的问题：
bogon:libexec luxiaoying$ pip install HttpRunner
/usr/local/Cellar/pyenv/1.2.1/pyenv.d/exec/pip-rehash/pip: /usr/local/bin/pip: /usr/local/Cellar/python3/3.6.4_2/bin/python3.6: bad interpreter: No such file or directory
问题原因：
使用pyenv 安装了Python 3.6.4版本，并设置为默认，但提示告知Cellar下面并没有Python3。
拿Android举个例子吧，上面这种情况就像是我们只下载了某个版本的Android api，但却没有安装Android SDK
也就是说，具体版本是要依赖于某个开发环境而存在的
解决方案：
使用 brew install python3 命令安装Python3环境，如下图所示。安装成功后再次运行：pip install HttpRunner ，错误消失。
