我是Python和Django的新手。
我正在使用PostgreSQL数据库引擎后端配置Django项目,但是每个数据库操作都出现错误。例如,当我跑步时manage.py syncdb,我得到:
manage.py syncdb
C:\xampp\htdocs\djangodir>python manage.py syncdb Traceback (most recent call last): File "manage.py", line 11, in <module> execute_manager(settings) File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 438, in execute_manager utility.execute() File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 379, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 261, in fetch_command klass = load_command_class(app_name, subcommand) File "C:\Python27\lib\site-packages\django\core\management\__init__.py", line 67, in load_command_class module = import_module('%s.management.commands.%s' % (app_name, name)) File "C:\Python27\lib\site-packages\django\utils\importlib.py", line 35, in im port_module __import__(name) File "C:\Python27\lib\site-packages\django\core\management\commands\syncdb.py" , line 7, in <module> from django.core.management.sql import custom_sql_for_model, emit_post_sync_ signal File "C:\Python27\lib\site-packages\django\core\management\sql.py", line 6, in <module> from django.db import models File "C:\Python27\lib\site-packages\django\db\__init__.py", line 77, in <modul e> connection = connections[DEFAULT_DB_ALIAS] File "C:\Python27\lib\site-packages\django\db\utils.py", line 92, in __getitem __ backend = load_backend(db['ENGINE']) File "C:\Python27\lib\site-packages\django\db\utils.py", line 33, in load_back end return import_module('.base', backend_name) File "C:\Python27\lib\site-packages\django\utils\importlib.py", line 35, in im port_module __import__(name) File "C:\Python27\lib\site-packages\django\db\backends\postgresql\base.py", li ne 23, in <module> raise ImproperlyConfigured("Error loading psycopg module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg module: No mo dule named psycopg
有人可以告诉我发生了什么吗?
你需要安装psycopg2Python库。
安装 下载http://initd.org/psycopg/,然后将其安装在Python PATH下
下载后,轻松解压缩tarball并:
$ python setup.py install
或者,如果愿意,可以通过easy_install或pip进行安装。
(我更喜欢无缘无故地使用pip而不是easy_install。)
$ easy_install psycopg2
$ pip install psycopg2
组态 在设置 .py中
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'db_name', 'USER': 'db_user', 'PASSWORD': 'db_user_password', 'HOST': '', 'PORT': 'db_port_number', } }
