我的任务是让我们的部门进行游戏化，以激励员工。
我发现这是https://github.com/ngageoint/gamification-server这是NGA发布的开源游戏化服务器。
我已按照所有说明写信，但无法启动服务器。
一些信息：
平台 - Ubuntu 14 LTS
在游戏化开始之前安装的软件包：
PostgreSQL的
Python Python-dev
Git的
VIRTUALENV
我能够安装依赖项，但是当我进入第二个任务时＃34; paver createdb＆＃34;我收到以下错误：
---> pavement.createdb

更新 - 对于任何发现此代码且与同一事物挣扎的人。 在任务createdb和create_db_user下的pavement.py文件中，我添加了以下2行
import os
os.environ["DJANGO_SETTINGS_MODULE"]="gamification.settings"
- UPDATE -
终于有了工作。似乎在游戏化服务器的设置中缺少几个步骤。
在发布Paver createdb之前，我运行了paver install_fixture和paver sync_initial这对我进行了整理，服务器现在运行正常

好的，我设法自己解决这个问题。如果有人发现此代码并想将其用作游戏化服务器，请按照以下步骤操作：
这应该让事情顺利进行。请参阅我的原始帖子，了解我对某些文件所做的更改，这些更改也有助于正确设置服务器。
答案 1 :(得分：2)
在使用上述命令后，我仍然无法使用createdb和create_db_user命令创建数据库，用户和表。所以，我开始认为这可能是一个权限问题。
以下帮助我填充了数据库（注意这对大多数人来说可能是显而易见的，但不适合我）。
这些步骤适用于Ubuntu，但我认为只要Postgres 8.x或更高版本，Python2.7和VirtualEnv安装并运行，它们就可以在其他Linux类型上运行。
登录Postgres：
$ bash #=> run under bash if not already
$ export DJANGO_SETTINGS_MODULE="gamification.settings"
$ source ~/pyenv/gamification/bin/activate
$ sudo service postgresql start
$ psql -U postgres
postgres-# CREATE USER game_manager WITH PASSWORD 'supersecret';
postgres-# CREATE DATABASE gamification;
postgres=# GRANT ALL PRIVILEGES ON DATABASE gamification to game_manager;
postgres-# ALTER USER GRANT SELECT ON gamification to game_manager;
postgres-# ALTER USER GRANT INSERT ON gamification to game_manager;
postgres-# ALTER USER GRANT DELETE ON gamification to game_manager;
postgres-# ALTER USER GRANT RULE ON gamification to game_manager;
postgres=# GRANT ALL PRIVILEGES ON table-name to public; #=> this step may be unnecessary
$ python manage.py syncdb
$ python manage.py syncdb #=> run it again
$ python manage.py migrate gamification.core
$ python manage.py migrate gamification.badges
$ python manage.py migrate gamification.event
$ python manage.py migrate gamification.core #=> run it again
$ python manage.py migrate gamification.badges #=> run it again
$ python manage.py migrate gamification.events #=> run it again
忽视错误。它们（我认为）是因为上面帖子中提到的循环依赖性。
答案 2 :(得分：1)
<强>更新
仔细观察堆栈跟踪，似乎有循环引用来导入设置。
createdb任务导入设置＆gt;＆gt;游戏化（init py文件）导入core.models＆gt;＆gt;导入django用户＆gt;＆gt;导致导入设置以查找DEFAULT_CACHE_ALIAS ...
我认为你最好看看这是否是Gamification Server软件包的稳定版本。
原始回答：
完整错误是：
NotperlyConfigured：请求设置CACHES，但设置不是 配置。您必须定义环境变量 DJANGO_SETTINGS_MODULE或在访问之前调用settings.configure（） 设置。
Django（1.8）预设了CACHES setting所需的“默认”后端。因此，对于vanilla Django，它可以直接运行，不会声明CACHES设置。
对我来说，错误意味着Django设置对象未初始化。可能尚未加载settings.py（如果paver createdb不是Django管理命令，则可能）。
当我的settings.py出现语法错误并且解释器没有正确解析时，偶尔我发现了这种类型的错误。您可以尝试使用python shell并运行“import settings.py”直接检查它。
