Cannot find 'QR' from 'qrtools'

[sanderfoobar]

Just a message for those that are having trouble with from qrtools import QR or import qrtools; qrtools.QR()

I am using windows (py 3.5.0) and I got it to work by using:

from qrtools.qrtools import QR

As opposed to what the installation docs say.

Also; there seems to be a problem with the package 'zbar' as I cannot install it on my Windows machine but that's a problem with the zbar package.

Thanx for the info skftn, this helped me out a lot...sort of. Still sitting with the zbar dependency now unfortunately. I found a zbar wrapper for python 3 which works, but not with this package obviously. Would it be possible to get these two to "work" together? Package name is zbar-ctypes

I have the same issue here, and your fix doesn't work (I use Linux)

Some wrong with zbar installation, which only compitable with python 2.6 and bellow

[somdipdey]

If you are Mac OS user then do the following [1]:
$ brew install zbar
$ export LDFLAGS="-L$(brew --prefix zbar)/lib"
$ export CFLAGS="-I$(brew --prefix zbar)/include"
$ pip install zbarlight

If Debian then:
$ apt-get install libzbar0 libzbar-dev
$ pip install zbarlight # you can also use setuptools directly

This would take care of zbar issue for Python 3.X users! Took me 1 hours just to find this easy solution!

After this inside your python script import the following:
from qrtools import qrtools
from PIL import Image
import zbarlight

Hi, the tips to use "from qrtools.qrtools import QR" helped me to resolve my problem but now i face another one who says :
qr = qrtools.QR()
NameError: name 'qrtools' is not defined

Do you have an idea to fix it ?
Thanks.

Try installing the qrtools as mentioned here: https://github.com/primetang/qrtools

Thanks for the response, I've already done it with pip install qrtools and I've tried to clone the repo but nohting works. When i try to "import qrtools" I have the following error "qrtools has no module QR" and when I try to "from qrtools.qrtools import QR" I face the "name 'qrtools' is not defined" so I'm a bit lost ^^

from qrtools import qrtools
qr = qrtools.QR()

[Friday97]

from qrtools import qrtools
qr = qrtools.QR()

It still give error: "ModuleNotFoundError: No module named 'zbar'"
And I can't install zbar using pip: "ERROR: Command errored out with exit status 1: 'c:\users\astra\appdata\local\programs\python\python37-32\python.exe' -u -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'C:\Users\Astra\AppData\Local\Temp\pip-install-dfavmz_a\zbar\setup.py'"'"'; file='"'"'C:\Users\Astra\AppData\Local\Temp\pip-install-dfavmz_a\zbar\setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(file);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, file, '"'"'exec'"'"'))' install --record 'C:\Users\Astra\AppData\Local\Temp\pip-record-5p25l52d\install-record.txt' --single-version-externally-managed --compile Check the logs for full command output."

Please help

Tried all the methods still have that error

[saumy-mohit-13]

well this post worked for me :

[mardukbp]

Just use zbarlight (on Windows install it on WSL or try to compile it yourself):

from PIL import Image
import zbarlight

file_path = './qrcode.png'
with open(file_path, 'rb') as image_file:
    image = Image.open(image_file)
    image.load()

codes = zbarlight.scan_codes(['qrcode'], image)
print('QR codes: %s' % codes)

The other solution is to use pyzbar, fast and simple.

I've done this and I have zbar and zbarlight installed, ostensibly. But I still can't seem to get qrtools to find it.
