Python：在Windows中制作QR码

Question

I'm new to Python. I'm trying to run this script (gencards.py) in Windows, but he says I need to run "the qrencode command". I assume that means this library , or the more likely the windows port .

In the python script, he uses qrencode as so:

os.system("qrencode -o .tempqr.png -s 30 -m 0 -l H " + serial)

I've installed the windows library via the executable, I added qrcode.exe to PATH, and tried editing gencards.py to use "qrcode" or "qrcode.exe" but I always get

'qrcode' is not recognized as an intrnal or external command, operable program or batch file.

What am I doing wrong?

I'm using Python 2.7 on Windows7 x64.

Answer 1

the error message means that Windows does not know what to do with qrcode . Check if it's installed in your system, and if it's directory is included in your PATH environment variable

Answer 2

Try to break the problem down, by first checking if you can run the programm (btw, is it 'grencode' or 'grcode'?) using a command prompt. If you can't then check your PATH settings again. When you succeeded with the command prompt get back to your python script.
