4. 配置应用目录

C:\Users\Administrator>e:

E:\>cd python

E:\python>cd web

E:\python\web>virtualenv venv

New python executable in venv\Scripts\python2.7.exe

Not overwriting existing python script venv\Scripts\python.exe (you must use ven

v\Scripts\python2.7.exe)

Installing distribute...........................................................

................................................................................

...............................................done.

Installing pip..............done.

E:\python\web>

5.激活virtualenv 中的 Flask:

E:\python\web>venv\Scripts\activate.bat

(venv) E:\python\web>pip install Flask

Requirement already satisfied (use --upgrade to upgrade): Flask in c:\python27\l

ib\site-packages

Requirement already satisfied (use --upgrade to upgrade): Werkzeug>=0.7 in c:\py

thon27\lib\site-packages (from Flask)

Requirement already satisfied (use --upgrade to upgrade): Jinja2>=2.4 in c:\pyth

on27\lib\site-packages (from Flask)

(venv) E:\python\web>exit

6.进入E:\python\web目录编写app测试文件

from flask import Flask

app = Flask(__name__)

@app.route('/')

def hello_world():

    return 'Hello World!'

if __name__ == '__main__':

    app.run()

7.运行脚本
