Zbar安装错误

Question

它是早些时候安装的，但是这个错误再次出现。

sudo apt-get install libzbar-dev

安装Zbar时会出现此错误。

pip3 install zbar

错误

Answer 1

试一试，对于pyhon3

sudo apt install python3-zbar

对于python2

sudo apt install python-zbar

Answer 2

或者，使用zbarlight，这是zbar的简单包装器。在GitHub上，最后一次提交是在2020年(zbar-py为2019年)，它有156颗星(zbar-py为80 )。
