Windows下安装Web.py快速指南

环境介绍

首先介绍下安装使用的环境

- Windows 7

- Python 3.6

Web.py介绍

web.py是Python在Web领域一个轻量级的解决方案，所谓轻量，就是非常简单快速满足Web页面开发的需求。

首先来感受一下其轻量的程度吧：

import web

urls = (
'/(.*)', 'hello'
)

class hello:
def GET(self, name):
i = web.input(times=1)
if not name: name = 'world'
for c in xrange(int(i.times)): print 'Hello,', name+'!'

if __name__ == "__main__": web.run(urls, globals())

综合来看，是不是非常的轻量….

安装指南

目前默认的web.py版本是0.38， 只要是针对python2而打包的，针对Python3是无法通过pip3的方式来直接安装的：

在安装之前，需要提前安装2个依赖包：

pip3 install db

pip install utils

直接安装web.py会报出若干错误信息：

C:\Users\xx>pip3 install web.py

Collecting web.py

Using cached web.py-0.38.tar.gz

Complete output from command python setup.py egg_info:

Traceback (most recent call last):

File “”, line 1, in

from web import version

File “C:\Users\CHENJU~1\AppData\Local\Temp\pip-build-vxm84t4s\web.py\web__init__.py”, line 14, in

File “d:\program files\python\lib\site-packages\db__init__.py”, line 69

print “var”, var

^

SyntaxError: Missing parentheses in call to ‘print’

----------------------------------------

Command “python setup.py egg_info” failed with error code 1 in C:\Users\xx~1\AppData\Local\Temp\pip-build-vxm84t

从错误信息来看，其错误为print在不同的Python版本下的语法上的差异造成的。

所以，我们直接从github上下载源代码，进行编译安装。

切换到python3的分支上，直接下载器源代码：

打开其地址： https://github.com/webpy/webpy/tree/python3

git clone https://github.com/webpy/webpy.git

待下载完成之后，进入下载目录，进行安装：

python setup.py install

结果信息：

D:\OpenSource\webpy>python setup.py install

从结果信息来看，其中依然存在若干错误信息，对于Python3而言，这些都是在python2下的语法在Python 3下无法被正确解析的问题，估计在后续版本，可以将python2的内容在python 3的分支上逐步更新。

目前的这个分支还是dev分支，存在若干问题还是可以理解的。

总结

web.py的这位作者已经仙逝，继任者还需努力，继续更新呀，从github上最后一次提交是在2017年初，不知道是否绝版了……
