hi,I found this project just now and I was surprised that C program can run on jupyternotebook. But after I install jupyter-c-kernel by

sudo pip3 install jupyter-c-kernel
sudo install_c_kernel
jupyter notebook

I try to run a simple C program

#include <stdio.h>
int main(){
    printf("hello world");
    return 0;
}

there is no any output in jupyter notebook cell,and the jupyter shell output

Does not exist that file or directory

I've try to uninstall jupyter-c-kernel by sudo pip3 uninstall jupyter-c-kernel, but the C kernel still shows in the GUI interface

after I try to install jupyter-c-kernel again by

pip install jupyter-c-kernel --user
install-c-kernel --user
jupyter notebook

I got the same error. I do not know how to solve it, maybe I know too title about Jupyter notebook or Ipython anyway, thanks for your work.

I just sovled it by copying the resources folder but I do not know why

@ScienceYuan can you elaborate please how did you solve it?

[YAGregor]

@Daniel-M I just copy the resource floder where the jupyter-c-kernel was installed (I use anacoda,so for me it is in /home/username/anacoda3/lib/python3.6/site-packages/jupyter_c_kernel) to its uppper floder(for me it's /home/username/anacoda3/lib/python3.6/site-packages/).

you may had sovled that.
