How to fix “No module named 'kivy._clock'” error in ubuntu?

问题

I'm trying to install "kivy" (GUI lib) with Ubuntu 16.04 for Python 3.6

I tried doing the steps in the kivy official website (https://kivy.org/doc/stable/installation/installation-linux.html)

I entered in the terminal:

sudo add-apt-repository ppa:kivy-team/kivy
sudo apt-get update
sudo apt-get install python3-kivy

And when I tried to import:

from kivy.app import App

I get the error:

ModuleNotFoundError: No module name 'kivy._clock'

回答1:

Try this in terminal:

• Make sure you have pip installed for python3

$ sudo apt-get install python3-pip

• Uninstall python3-kivy

$ sudo apt-get purge python3-kivy

• Figure out your python3 version; note the first two digits:

$ python3 -V

Output:

Python 3.7.3

• Find the latest build nightly build / wheels links here: https://kivy.org/downloads/ci/linux/kivy/

  Copy the link of the latest build that has a cpXX value in the file name that matches the first two digits of your python3 version. For me, this is cp37.

• Finally, put the link in the relevant section of the next command:

$ python3 -m pip install [linkherewithoutbrackets] --user

---

This fixed the same error for me with: Debian 10, python3 v3.7.3. This ultimately installed kivy v2.0.0rc1.

Resources should links change in the future:

• For determining compatible cython versions: https://kivy.org/doc/stable/installation/deps-cython.html

• For the linux install instructions (and where I found the nightly wheels build link): https://kivy.org/doc/stable/installation/installation-linux.html
