Python Kivy Is Printing numbers while importing it

问题

I just installed Kivy in my virtualenv

I installed it using pip install https://github.com/kivy/kivy/archive/master.zip

My dependencies

Python 2.7.10
Kivy==1.10.1.dev0
Cython==0.26.1
Kivy-Garden==0.1.4

When I tried to run it in my terminal using command from kivy.app import App

Its printing integers recursively I have attached screenshot below

Thanks in advance!!

I Have Raised A GIT ISSUE ALSO :- https://github.com/kivy/kivy/issues/5515

回答1:

I'll propose a workaround: it's to turn off printing from python during imports. It's lame but will fix in while they're fixing the forgotten print properly:

import sys

def write(x):
    pass
saved = sys.stdout.write
sys.stdout.write = write

from kivy.app import App  # works for any import that uses stdout to print stuff

sys.stdout.write = saved

just save sys.stdout.write, then override it with a method that does nothing, then import. Restore standard output after importing.

I've tested it with a custom module that prints stuff when imported, and it suppresses the prints. If it doesn't work, the same thing can be tried with sys.stderr.write

Kivy has no support to python 2.7 so kindly update your python to 3x then reinstall kivy I guess it will work!!

Cheers
