当我按照教程操作Django时，我遇到了操作系统错误

Question

我在Django for Beginners上学习了教程(我现在正在学习第3部分)。当我在127.0.0.1:8000上运行站点时，我在修复操作系统错误时遇到了问题。我有一台ModuleNotFoundError，我觉得问题出在我的settings.py上。当我的虚拟环境处于活动状态时，我输入了python manage.py runserver。

我得到的错误如下: OSError: WinError 123文件名、目录名或卷标语法不正确。ModuleNotFoundError:没有名为widget-tweaks的模块。

这是我的settings.py文件。这就是我添加django-widget调整的地方。

        {% endif %}
      </div>
    {% endfor %}

    <button type="submit" class="btn btn-success">Post</button>
  </form>
{% endblock %}

我的最终目标是获得一个呈现的表单，但是ModuleNotFoundError不让我呈现表单或运行网页。我试着使用pip install django-widget-tweaks卸载并重新安装widget-tweaks，但它仍然给我一个错误和一段艰难的时间。

有人能教我怎么解决这个问题吗？当我第一次运行它时，我从来没有收到过这个错误。

Answer 1

根据installation instructions，INSTALLED_APPS中的值应该是widget_tweaks而不是widget-tweaks。

Answer 2

您应该在INSTALLED_APPS中用widget_tweaks替换小部件调整。
