1、git clone  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  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。
