Flask 从新认识

  老是觉的学习东西有点猴子掰玉米的感受。今天就从新再掰一次吧。html

  Installation:python

    安装以前建议先安装virtualenv,这个东东是帮助你在多个python版本之间保持同步,不至于python版本变化了,项目就奔溃了。linux

    某些程序猿的装备好些,可能用的是mac,自有类linux的安装方法。无奈本屌丝只能在win下来写写程序。因此只提供win的virtualenv安装方法:git

      到这里下载http://flask.pocoo.org/docs/installation/#windows-easy-install, 建立python 文件,拷贝 distribute_setup.py的内容。而后双击便可。flask

      也可参考这篇文章,很是详细:http://f.dataguru.cn/thread-36396-1-1.htmlwindows

 

     1. 安装pip : easy_install.py pipide

     2. 安装virtualenv: easy_install.py virtualenv学习

         安装完成记得在环境变量里面添加路径。ui

 

APP:spa

  如今新建立一个文件夹,给这个文件夹设置python环境。

  

F:\>cd flask

F:\flask>cd picshow

F:\flask\picshow>virtualenv env
New python executable in env\Scripts\python.exe

F:\flask\picshow>

  接下来激活这个环境

env\Scripts\activate

  最后,为应用添加Flask:

F:\flask\picshow>env\Scripts\activate
