Flask 從新認識

  老是覺的學習東西有點猴子掰玉米的感受。今天就從新再掰一次吧。

  Installation：

    安裝以前建議先安裝virtualenv，這個東東是幫助你在多個python版本之間保持同步，不至於python版本變化了，項目就奔潰了。

    某些程序猿的裝備好些，可能用的是mac，自有類linux的安裝方法。無奈本屌絲只能在win下來寫寫程序。因此只提供win的virtualenv安裝方法：

      到這裏下載http://flask.pocoo.org/docs/installation/#windows-easy-install, 建立python 文件，拷貝 distribute_setup.py的內容。而後雙擊便可。

      也可參考這篇文章，很是詳細：http://f.dataguru.cn/thread-36396-1-1.html

 

     1. 安裝pip ： easy_install.py pip

     2. 安裝virtualenv: easy_install.py virtualenv

         安裝完成記得在環境變量裏面添加路徑。

 

APP:

  如今新建立一個文件夾，給這個文件夾設置python環境。

  

F:\>cd flask

F:\flask>cd picshow

F:\flask\picshow>virtualenv env

  接下來激活這個環境

env\Scripts\activate

  最後，爲應用添加Flask：

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