Flask 重新认识

总是觉的学习东西有点猴子掰玉米的感觉。今天就重新再掰一次吧。

Installation：

安装之前建议先安装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。

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。所以只提供win的virtualenv安装方法：

到这里下载http://flask.pocoo.org/docs/installation/#windows-easy-install, 创建python 文件，拷贝 distribute_setup.py的内容。然后双击即可。

也可参考这篇文章，非常详细：http://f.dataguru.cn/thread-36396-1-1.html

1. 安装pip ： easy_install.py pip

2. 安装virtualenv: easy_install.py virtualenv

安装完成记得在环境变量里面添加路径。

APP:

现在新创建一个文件夹，给这个文件夹设置python环境。

F:>cd flask

F:flask>cd picshow

F:flaskpicshow>virtualenv env
New python executable in envScriptspython.exe

接下来激活这个环境

envScriptsactivate

最后，为应用添加Flask：

F:flaskpicshow>envScriptsactivate
(env) F:flaskpicshow>pip install Flask
