Question

使用python3 manage.py runserver命令运行django站点时出现问题。我已经安装了django-bootstrap-ui包并将正确的名称添加到我的INSTALLED_APPS中，但仍然会收到以下错误：

(django_env)my_machine@my_pc:~/srv_django/etransphere$ python3 manage.py runserver

运行pip list和pip show django-bootstrap-ui都显示该软件包已安装在我的虚拟环境中

Answer 1

我在使用Python3时发现msissing包的问题是我使用pip运行我的软件包的安装：

pip install django-bootstrap-ui

而不是pip3。

sudo -H pip3 install django-bootstrap-ui

安装django时我使用了pip3，因此应用程序开始使用Python3库和site-packages。使用pip安装任何软件包都会将文件解压缩到我的django安装没有使用的Python2目录中（回想一下我使用pip3来安装django）。但是，使用pip3将添加的包压缩到我的django安装使用的Python3目录中，从而可以看到包。消除错误：D

Answer 2

这是因为在 settings.py 和 urls.py 中安装新应用时出错。在编辑这些文件以添加新应用程序后，我遇到了同样的错误。

<强>解决方案：检查 urls.py

urlpatterns = [
url(r'^admin/', admin.site.urls),
*#this may be the place where you entered the app url but created an syntax error.*

并检查 settings.py

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',

当您在INSTALLED APPS列表中输入应用名称时，您可能输入了错误的名称

我的错误原因：我输入应用名称后忘记输入逗号

INSTALLED_APPS = [
'appName'  <<<<<<< 
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',

python3 manage.py runserver
