I just installed Anaconda 3 following the instructions of the Windows 10 installer. Now I want to launch a jupyter notebook from the command line but I get the error :

_cffi_ext.c
Anaconda3\lib\site-packages\zmq\backend\cffi\__pycache__\_cffi_ext.c(213): fatal error C1083: Impossible d'ouvrir le fichier include : 'sys/un.h' : No such file or directory

    from . import (constants, error, message, context,
ImportError: DLL load failed: Le module spécifié est introuvable.

After the installation I did 2 things :

  • run conda init in the terminal
  • add path to Anaconda3 and to Anaconda3\Scripts to my Path environment variable.

Thank you for your help,

  • Yes it does ! Since I want to be able to launch a jupyter notebook without activate base environement I have added the following to mentionned paths to my Path environnement variable. – Marco Lafon Jan 09 '20 at 22:09
