Answer 1

You could try running pyinstaller in a different virtual environment.

To do so on Linux.

1. Install virtualenv

2. In a shell:

   • Create an environment with virtualenv env_name - This will create a "env_name" folder in your home directory

   • Activate the virtual environment with source activate env_name

   • Now you are in an environment whith no installed libraries

   • Install cython with pip install cython==0.26 - Latest version is 0.27.3, but kivy 1.10 failed to compile while using that, this could change in the future
   • Install kivy with pip install kivy
   • Install pyinstaller and any other dependance of your project
   • Run pyinstaller with env_name/bin/pyinstaller script.py - This is needed since, by running pyinstaller you would use the one in your original python installation

This should resonably reduce the amount of unneeded libraries in the package, just make sure you don't forget to install anything

Also, notice i didn't use sudo in the pip install commands, that's because you don't need it inside the virtual environment, and using it could compromise the result
