问题描述

我有一个网站托管在 Heroku ，我现在想使用 python-qrtools 包使用 ZBar条形码扫描器。在一个常规的debian（基于）我可以做一个简单的：

  sudo apt-get install python-qrtools

根据命令 dpkg-query -L python-qrtools 这将安装以下内容：

  /usr/lib/python2.7/dist-packages/qrtools-1.2.egg-info 
 /usr/lib/python2.7/dist-packages/qrtools.py 
 / usr / share / doc / python-qrtools / copyright 
 / usr / share / doc / python-qrtools / changelog.Debian.gz

当我查看导入的 qrtools.py ，它也是一个 import zbar ，这是（据我所知）ZAR包的python绑定（此处的Pipi链接）。我很惊讶，zbar或其python绑定不在列表中，而 python-qrtools apt包。所以我的第一个问题：



这个zbar软件包安装的时间和地点在哪里？



这个ZBar buildpack 安装ZBar，所以我只需要安装zbar的Python绑定。从python命令行我已经看到它是源自.so文件的绑定：

 >>>导入zbar 
>>> zbar .__ file__ 
'/usr/lib/python2.7/dist-packages/zbar.so'

所以我做了一个简单的 sudo pip install zbar ，这不幸导致我下面粘贴了大量的编译错误。所以我的主要问题实际上是如下：



如何单独安装zbar python绑定（所以没有apt）？所有提示都是欢迎！

所以我试图使用



分别安装Python zbar绑定不幸的是，我甚至似乎无法在linux上安装zbar软件包

解决方案

  sudo apt-get install libzbar-dev 
 sudo pip install zbar

通常是一个-dev包，当您收到这些错误时，您会丢失一个简单的方法软件包是 apt-cache search 如下所示：

 〜$ apt -cache search zbar 
 libbarcode-zbar-perl  - 条形码扫描器和解码器（Perl绑定）
 libzbar-dev  - 条形码扫描器和解码器（开发）
 libzbar0  - 条码扫描器和解码器（库）
 libzbargtk-dev  - 条码扫描器和解码器（GTK +绑定开发）
 libzbargtk0  - 条形码扫描器和解码器（GTK +绑定）
 libzbarqt-dev  - 条形码扫描器和解码器（Qt绑定开发）
 libzbarqt0  - 条形码扫描器和解码器（Qt绑定）
 python-qrtools  - 用于读取和生成QR码的高级库
 python-zbar  - 条形码扫描器和解码器（Python绑定）
 python-zbarpygtk  - 条形码扫描器和解码器（PyGTK绑定）
 zbar-dbg  - 条形码扫描器和解码器（调试）
 zbar-tools  - 条码扫描器和解码器（实用程序）

FWIW，我用来安装的程序是 python-qrtools ， libzbar-dev 最后 pip install zbar p>

I've got a website hosted at Heroku, and I now want to use the python-qrtools package which uses the ZBar bar code scanner. On a regular debian (based) I can do a simple:

sudo apt-get install python-qrtools

According to the command dpkg-query -L python-qrtools, this installs the following:

/usr/lib/python2.7/dist-packages/qrtools-1.2.egg-info
/usr/lib/python2.7/dist-packages/qrtools.py
/usr/share/doc/python-qrtools/copyright
/usr/share/doc/python-qrtools/changelog.Debian.gz

When I look at the imports of qrtools.py, it also does an import zbar, which is (as far as I understand) the python binding for the Zbar package (Pypi link here). I'm kinda surprised that zbar or its python bindings are not in the list with the python-qrtools apt package though. So my first question:

When and where is this zbar package installed?

Moving on I decided to install ZBar and the python binding for it on Heroku. I managed to install ZBar using this ZBar buildpack so I only need to instal the zbar Python binding. From the python command line I already see that it is a binding originating from a .so file:

>>> import zbar
>>> zbar.__file__
'/usr/lib/python2.7/dist-packages/zbar.so'

So I did a simple sudo pip install zbar, which unfortunately results in a massive compiling error which I pasted below. So my main question is actually the following:

How do I install the zbar python bindings separately (so without apt)? All tips are welcome!

Downloading/unpacking zbar
  Downloading zbar-0.10.tar.bz2
  Running setup.py (path:/tmp/pip_build_root/zbar/setup.py) egg_info for package zbar

Installing collected packages: zbar
  Running setup.py install for zbar

 #include <zbar.h>

                  ^

compilation terminated.

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

So I tried to install the Python zbar binding separately using

Unfortunately I don't even seem to be able to install the zbar package on linux

解决方案 

sudo apt-get install libzbar-dev
sudo pip install zbar

It is usually a -dev package that you are missing when you get those kind of errors, an easy way to find the package is apt-cache search like below:

~$ apt-cache search zbar
libbarcode-zbar-perl - bar code scanner and decoder (Perl bindings)
libzbar-dev - bar code scanner and decoder (development)
libzbar0 - bar code scanner and decoder (library)
libzbargtk-dev - bar code scanner and decoder (GTK+ bindings development)
libzbargtk0 - bar code scanner and decoder (GTK+ bindings)
libzbarqt-dev - bar code scanner and decoder (Qt bindings development)
libzbarqt0 - bar code scanner and decoder (Qt bindings)
python-qrtools - high level library for reading and generating QR codes
python-zbar - bar code scanner and decoder (Python bindings)
python-zbarpygtk - bar code scanner and decoder (PyGTK bindings)
zbar-dbg - bar code scanner and decoder (debug)
zbar-tools - bar code scanner and decoder (utilities)

FWIW, the procedure I used to install was python-qrtools ,libzbar-dev and finally pip install zbar.
