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，默認只有system

3、查看可以安裝的Python版本

pyenv?install?--list

4、官方建議Python3.6版本，so，安裝需要的Python版本

pyenv install 3.6.2

5、切換Python版本，將Python 3.6.2置為默認

pyenv global 3.6.2,? *號代表默認版本

特別建議：

優先級關系：shell——local——global

6、啟動服務 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、安裝Flask-Script失敗，error: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/itsdangerous.py'

iwm@bogon  /usr/local/Cellar  pip install Flask-Script

9、chomd賦予權限

sudo chmod 777 /Library/Python/2.7/site-packages/

10、再次執行pip install Flask-Script

11、若第七步報如下錯誤，使用：pip --trusted-host?pypi.python.org?install Flask-Script

12、啟動httprunner，提示未發現HttpRunner強依賴的?'PyUnitReport'?

13、install PyUnitReport

14、install PyYAML

15、install requests

16、install pyOpenSSL

17、?hrun -V

18、cd httprunner根目錄下，執行export FLASK_APP=tests/api_server.py

19、接著執行flask run

遇到的問題：

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

問題原因：

使用pyenv 安裝了Python 3.6.4版本，并設置為默認，但提示告知Cellar下面并沒有Python3。

拿Android舉個例子吧，上面這種情況就像是我們只下載了某個版本的Android api，但卻沒有安裝Android SDK

也就是說，具體版本是要依賴于某個開發環境而存在的

解決方案：

使用 brew install python3 命令安裝Python3環境，如下圖所示。安裝成功后再次運行：pip install HttpRunner ，錯誤消失。
