Can't install zbar

问题:

I am trying to use the qrtools module with Python 3.4.2 on my Raspberry Pi 2, however it cannot run as I don't have the zbar module installed. Trying

pip-3.2 install zbar 

Gives the error message shown in the picture

sudo pip-3.2 install zbar 

gives a similar error

Any ideas?

(I do have it installed with Python 2.7)

UPDATE: Both libzbar-dev and python3-dev are up to date. Still...

No module named  'zbar'  

回答1:

assuming you're using a debian derivative (like ubuntu), you need to install zbar's developement package, which contains the header file zbar.h

$ sudo apt-get install libzbar-dev 

for redhat/fedora systems:

$ sudo yum install zbar-devel 

and probably python's dev package too:

$ sudo apt-get install python3-dev
