如何修复 edx-platform 中的 django 应用程序错误

Question

我想在https://github.com/edx/edx-platform 中添加一个新应用。 我正在关注这个https://docs.djangoproject.com/en/2.2/intro/tutorial01/ 文档

/edx/app/edxapp/edx-platform/myapp/url.py

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')),

我的错误

ImportError: cannot import name path

我哪里出错了。请告诉我。

  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

上面的错误是说你不能从django.conf.urls导入path。看来您使用的是旧版本的 django。所以，尝试以下命令安装旧版本。

$ pip install Django==1.11

然后转到文件 /edx/app/edxapp/edx-platform/lms/urls.py 并从导入中删除 path。然后它看起来像下面。

from django.conf.urls import include, url
