正如在stackoverflow上提到这个问题一样，以下程序已经尝试但不能正常工作：

sudo apt-get install build-essential
sudo apt-get install bzip2
sudo apt-get install bzip2-dev
sudo apt-get install gcc
sudo apt-get install gcc-4.4
sudo apt-get install libbz2
sudo apt-get install libbz2-dev
sudo apt-get install libevent
sudo apt-get install libevent1-dev
sudo apt-get install libevent-dev
sudo apt-get install libgcc
sudo apt-get install libgcc1
sudo apt-get install libgcc1-4.7-dev
sudo apt-get install libgcc1-dev
sudo apt-get install libgcc-4.8-dev
sudo apt-get install libpython3.4-dev
sudo apt-get install libpython3.4-stdlib
sudo apt-get install libpython3-dev

sudo apt-get install openssl
sudo apt-get install python3.4-dev
sudo apt-get install python3.4-devel
sudo apt-get install python3-dev
sudo apt-get install python3-devl
sudo apt-get install python3-gcc
sudo apt-get install python-dev
sudo apt-get install python-devel
sudo apt-get install python-setuptools

虽然像朋友建议的那样安装libzbar-dev，但错误信息似乎有所不同，但仍无法正常工作

我怎么能解决这个问题？谢谢你的所有答案

Answer 1

从另一篇文章看起来无关紧要我找出解决方案

ImportError: No module named zbar on Linux Mint

但是只有zbar-tools不足以获得好结果，我投入了

sudo apt-get install zbar-

并按TAB然后找到zbar-dbg，只是试一试，它确实有效。

sudo apt-get install zbar-tools zbar-dbg

当zbar问题导致的gcc错误确实让我感到震惊。也许有些人对类似问题有所启发，所以我把它放在这里。
