from django.conf.urls import url
from . import views
urlpatterns = [
   url('', views.hello, name = 'hello'),
]

/edx/app/edxapp/edx-platform/lms/envs/common.py

INSTALLED_APPS = [
    # Standard ones that are always installed...
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.humanize',
    'django.contrib.messages',
    'django.contrib.redirects',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.staticfiles',
    'djcelery',
    'myapp',
     .............

/edx/app/edxapp/edx-platform/lms/urls.py

urlpatterns = [
    url(r'^$', branding_views.index, name='root'),   # Main marketing page, or redirect to courseware

    url(r'', include('student.urls')),
    # TODO: Move lms specific student views out of common code
    url(r'^dashboard/?$', student_views.student_dashboard, name='dashboard'),
    url(r'^change_enrollment$', student_views.change_enrollment, name='change_enrollment'),
    url(r'^myapp/', include('myapp.urls')),

    from django.conf.urls import include, url, path
ImportError: cannot import name path

Where I am going wrong. please let me know.

Solution

  File "/edx/app/edxapp/edx-platform/lms/urls.py", line 6, in <module>
    from django.conf.urls import include, url, path
ImportError: cannot import name path

The above error is saying that you can't import path from django.conf.urls. It seems you are using older version of django. so, try the following command to install old version.

$ pip install Django==1.11

and go to file /edx/app/edxapp/edx-platform/lms/urls.py and remove path from import. Then it looks like below.

from django.conf.urls import include, url
