El error se puede generar presionando "Ctrl + S" para recargar Django y no
es necesario realizar algún cambio en el código para obtener el error que
parece ser aleatorio. Por lo pronto lo solucioné regresando a Django 2.1.4
Algunas veces funciona bien e informa lo siguiente:
{{{
System check identified no issues (0 silenced).
April 11, 2019 - 19:29:25
Django version 2.1.4, using settings 'base.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
}}}
En ocasiones pasa lo siguiente y es muy repetitivo:
{{{
/home/irvin/Documentos/Proyectos/REST-env/base/snippets/views.py changed,
reloading.
