QR码解码器库为python

我想在python中编译和解码QR码的应用程序。我用编码器成功了，但是我没有找到用于在python中解码的库（但是zbar）。我在Windows 7系统中使用Python 2.7。我不能在我的系统中安装zbar。我安装了库所需的依赖模块，甚至在我试图安装它时，最终会出现很多错误 - 在zbar.h和zbarmodule.c中出现了很多的语法错误。我不明白为什么，也不知道问题是什么。QR码解码器库为python

我收到以下错误，同时安装zbar和

什么是错误？ – geoffspear 2012-02-16 11:29:52

请过去的错误，让人们可以了解你在做什么 – Nilesh 2012-02-16 11:34:08

我已经包括了错误，请通过并告诉我什么是问题。感谢@lafada和wooble。 – vijay 2012-02-17 03:48:51

pyqrcode支持编码和解码QR码。

关于zbar，正如其他人所评论的，在不知道任何错误消息的情况下很难帮助您。

你是否从Windows二进制包或源代码安装zbar？

zbar有一个预编译的Windows二进制包可用here，它也有二进制Python模块2.5和2.6可用here。

关于zbar和安装通过看到这些zbar Installation Instructions

的需要基于上述链接以安装从源zbar和Python模块上采取如下所示的步骤的总结。

（从二进制here最好）
安装zbar和安装MinGW
添加zbar和\ BIN和MinGW \ BIN（二进制安装目录）到Windows路径变量
下载zbar和Python模块源自here并将其解压缩到临时文件夹
修改setup.py脚本以使用自定义zbar包含和库路径。

添加from distutils.sysconfig import get_config_vars排队3和以下参数添加到分机呼叫：
```
library_dirs=["""zbarlibdirectory"""], 
    include_dirs=[get_config_vars('INCLUDEDIR'), 
        get_config_vars('INCLUDEPY'), 
        """zbarincludedirectory"""] 
```
其中zbarlibdirectory是像C:\zbar\lib和zbarincludedirectory是一样的东西C:\zbar\include
安装zbar和Python模块使用修改建立。PY

python setup.py build --compiler=mingw32

python setup.py install

至于Windows7的上安装pyqrcode，我没有那么做，但认为自己只是为相关标题下的来源的指示，先安装所有的依赖然后运行make并使用nmake进行安装，或者使用MinGW进行安装。

感谢@Appleman的回答。现在如何在Windows中安装pyqrcode？我已经包含了我在zbar中得到的错误，我从源代码安装了它（使用easy_install从[zbar]（http://pypi.python.org/pypi/zbar/0.10）打包到pypi） – vijay 2012-02-17 03:57:33
