New Kivy installation: AttributeError: 'module' object has no attribute 'require'

Question

kivy 1.10.0, python 3.4.5, windows 10, using Anaconda's Spyder IDE

After much trouble trying to install kivy on my windows 10 computer, I was able to...sort of. I downgraded python to the most recent supported version.

I put in kivy's stock code to make sure it's working:

import kivy
kivy.require('1.0.6') # replace with your current kivy version !

from kivy.app import App
from kivy.uix.label import Label


class MyApp(App):

    def build(self):
        return Label(text='Hello world')


if __name__ == '__main__':
    MyApp().run()

Changing my version to 1.10.0. But I got the following error and trace back:

Traceback (most recent call last):

File "<ipython-input-6-498c1728e978>", line 1, in runfile('C:/Users/Andrew/Documents/Programming/Kivvv/UsageExample.py', wdir='C:/Users/Andrew/Documents/Programming/Kivvv')

File "C:\Users\Andrew\Anaconda3\lib\site-packages\spyder\utils\site\sitecustomize.py", line 866, in runfile execfile(filename, namespace)

File "C:\Users\Andrew\Anaconda3\lib\site-packages\spyder\utils\site\sitecustomize.py", line 102, in execfile exec(compile(f.read(), filename, 'exec'), namespace)

File "C:/Users/Andrew/Documents/Programming/Kivvv/UsageExample.py", line 12, in kivy.require('1.10.0') # replace with your current kivy version !

AttributeError: 'module' object has no attribute 'require'

Also ran

print(dir(kivy))

which returned this list:

['doc', 'loader', 'name', 'package', 'path', 'spec']

My guess is that kivy didn't install properly, but I've had so many troubles installing it that I don't want to reinstalling it until that is clearly the next best option.

Also, if it helps, when running the kivy installation process on the kivy website, several steps return an error regarding "splitlines" even though each step successfully finishes--

Exception:

Traceback (most recent call last):

parts = data.splitlines(True)

AttributeError: 'NoneType' object has no attribute 'splitlines'

Not sure if it make a difference, but I decided to include it in case it is a good clue to what's going on.

Thanks so much!!!

Update, 5-12-17:

I went ahead and tried the program by pasting it in notepad and running it from there, but I got the same error message.

I then did

python -m pip list 

in the powershell, and none of these popped up:

Kivy (1.10.0)
Kivy-Garden (0.1.4)
kivy.deps.angle (0.1.4)
kivy.deps.glew (0.1.9)
kivy.deps.sdl2 (0.1.17)

It looks like kivy didn't install after all. After trying to run the installation again, here is what my computer shoots back at me:

Since I'm not getting that "kivy installed" message, it looks like this "splitlines" attribute error is preventing the installation from finishing. Any idea how I can fix this?

Answer 1

It's showing error because of the File name you are saving the file with name 'kivy.py' which inturn is contradicting with kivy core package. Try renaming the file Hope it helps.

Answer 2

So it seems more likely to me that your issue is with the ide. In fact if I was a betting man I'd bet everything I have that your IDE is the issue.

Please go through my answer and try the two scripts I posted. The most important thing you NEED to do now is paste the python code into notepad and run it through your command line.

If it works, you know what your issue is. If it doesn't try all the steps I've listed below. It's very possible that your ide is pointing to the wrong path(s) or something along those lines.

Try the following things please.

Step 1:

python -m pip list 

Locate your kivy install and verify it's there, and it's version. You should see something like

Kivy (1.10.0)
Kivy-Garden (0.1.4)
kivy.deps.angle (0.1.4)
kivy.deps.glew (0.1.9)
kivy.deps.sdl2 (0.1.17)

If you see that stuff copy paste the below example and try running it.

Step 2: Script

import kivy


from kivy.app import App
from kivy.uix.label import Label


class MyApp(App):
    def build(self):
        return Label(text='Hello world')


if __name__ == '__main__':
    MyApp().run()

If you get the same errors.

Try the following python -m pip show kivy

You should see something like

Name: Kivy
Version: 1.10.0
Summary: A software library for rapid development of hardware-accelerated 
multitouch applications.
Home-page: http://kivy.org
Author: Kivy Team and other contributors
Author-email: kivy-dev@googlegroups.com
License: MIT
Location: c:\python36-32\lib\site-packages
Requires: pygments, Kivy-Garden, docutils

If you see this and even if you don't run the following command

python -m pip check kivy

This will tell you if you've met all the required dependencies for kivy. If not go through and install them.

There could be issues that I can't help you with based off of the current information that I have so my last piece of advice would be to do this as a last resort.

python -m pip uninstall kivy
python -m pip install kivy==1.10.0

Update: I've never used power shell so I don't know how it operates. Try using the command promot. Also you're using Anacondas IDE but are you also using Anaconda Python? If so certain commands are different and you'd have to bypass it and use the official tools. To make sure it's not a compatibility issue. https://docs.continuum.io/anaconda/faq

From what I see in the error code your kivy install is there and fine. Which means it's directly related to spider.
