ImportError: No module named 'kiwisolver' about kiwi HOT 9 CLOSED

After 3+ hours of agony, the solution turned out to be quite simple.

Uninstall Kiwisolver:

pip3 uninstall kiwisolver
Then reinstalling Kiwisolver:

pip3 install kiwisolver

from kiwi.

sudo rm -r /usr/lib/python3/dist-packages/kiwisolver-1.0.1.egg-info
This command worked for me after searching everywhere basically uninstalling kiwisolve did not work for me so removed the entire kiwisolver directory

from kiwi.

Could you please post the full error message and the output of pip ? Running pip to install kiwisolver should be enough. As a side note it is usually better to avoid messing with your distro Python distribution by using virtual environment.

I have tried uninstalling and installed it once again. It is also not working.

Thanks.

Kiwi is implemented using C++ only (no python file) as a consequence you should only see a kiwisolver.***.so in site-packages in addition of the dist-info folder. Could you check whether or not it is present ?
The wheel are tested as part of the build process and I locally checked on MacOS that the python 3.5 wheel work. I will spin up a VM to check also on linux. In the meantime if you have a c++ compiler installed, you can try to install from source directly: pip3 install https://github.com/nucleic/kiwi/tarball/master/

I just tested on a fresh Docker image of ubuntu 16 and I can install without any issue on Python 3.5. Could there be something (like a folder named kiwisolver) on your path that would shadow the installed package ?

Hi @MatthieuDartiailh ,

I have installed as you have mentioned but same thing happened. But, I have noticed ont thing. Kiwisolver has been installed differently in my system. I don't know why. There are two things getting installed:

1. kiwisolver-1.1.0.dist-info
2. kiwisolver.cpython-35m-x86_64-linux-gnu.so (I haven't noticed this file has been installed)

I have copied this file into my Python path directory then I'm not getting the error. First time I'm seeing this file getting installed using pip command.

Thank you so much.

This is the expected file (once again this is related to the fact that kiwisolver is a single module implemented in C). I am wondering why site-packages is not on the path... but I am happy things work again for you.

I did have same issue ModuleNotFoundError: No module named 'kiwisolver' - what I found is that kiwisolver-1.1.0.dist-info was installed on ...AppData\Roaming\Python\Python37\site-packages. I deleted the entire folder kiwisolver-1.1.0.dist-info and reinstalled with pip3 install kiwisolver. Now it is installed on ...\appdata\local\programs\python\python37\lib\site-packages and tested the code it passed!
