Problems installing Cython

[Arturo Martínez Sandoval]

Hi,

I'm trying to package my App into a MacOs app. 

I'm following the instructions on https://kivy.org/doc/stable/guide/packaging-osx.html, and when I try to install Cython, this error shows up:

MacBook-Air-de-Arturo:~ Administrador$ pip install Cython==0.26.1

/Library/Frameworks/Python.framework/Versions/3.6/bin/pip:6: UserWarning: Unbuilt egg for Unknown [unknown version] (/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages)

  from pkg_resources import load_entry_point

Requirement already satisfied: Cython==0.26.1 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (0.26.1)

Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/~ython-0.28.2.dist-info/METADATA'

The same happens when I try to install PyInstaller.

I'm using a MacBook Air Mid-2013 with Mojave (10.14.3). 

I avoided using the Python built-in in the OS, so I installed Kivy in Python3 and developed in it my App.

Looks like there is a problem with your python installation. Note the "~ython" in your last line. I would suggest using a virtual environment and trying to install Kivy into that? Otherwise, try "sudo pip install Cython==0.26.1"

Hi, I tried installing it with sudo and this showed up:

You are using pip version 10.0.1, however version 19.0.1 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

Maybe the virtual environment works. The program is that I don't know how to create one. Can you help me? Do you know any tutorial or something like that?
