我一直在尝试在 django 项目中启动并运行一组基本的生菜测试，但我遇到了一些问题。

我按照生菜网站上的示例教程进行操作，但运行时不断出现以下错误python manage.py harvest：

Feature: Rocking with lettuce and django               #apps/my_app/features/index.feature:1

  Scenario: Simple Hello World                         # apps/my_app/features/index.feature:3
    Given I access the url "/admin"                    # apps/my_app/features/index-steps.py:12

2 steps (1 failed, 1 skipped, 0 passed)

我的虚拟环境中安装了以下内容：

Django==1.4.1
MySQL-python==1.2.3
South==0.7.6
Werkzeug==0.8.3
boto==2.6.0
cssselect==0.7.1
django-extensions==0.9
django-nose==1.1
django-storages==1.1.5
django-tastypie==0.9.11
fuzzywuzzy==0.1
lettuce==0.2.10
lxml==2.3.5
mimeparse==0.1.3
mock==1.0.0
nose==1.2.1
python-dateutil==1.5
selenium==2.25.0
sure==1.0.6
wsgiref==0.1.2

这是一个错误，还是我在某个地方犯了一些错误？我原以为这个例子会涵盖它......

显然，这个错误是一个红鲱鱼。我得到XMLSyntaxError是因为来自 URL 的响应是空的（在这种情况下，我正在检查的 URL 缺少尾部斜杠）。

因此，如果有人遇到此问题，请务必先验证您自己的代码是否有效，然后再指责他人的代码。
