Laravel路线不再工作

我正在学习Laravel，我正忙于构建一个网站（框架版本5.1.34）。我在去年9月安装了Homestead，最初在Windows 7上，然后升级到Windows 10。在Windows 7和后来的Windows 10上一切都很好（我在Windows 10上遇到了一些问题，我设法解决了），但最近我的路线开始变得奇怪。我的所有路线仍然有效，除了现在出现404错误的那条。路线是：

Route::get('projects/{project}/nodes/{node}/tasks/create', 
['uses' => 'TaskController@taskCreateShow']);

控制器功能为：

public function taskCreateShow(Project $project, Node $node){
    return view('tasks.create')
            ->with('project',$project)
            ->with('user',$this->user)
            ->with('node',$node)
            ->with('all_projects',$this->all_projects);
} // taskCreateShow

如果我运行php artisan route:list，该路由仍然像所有其他路由一样显示。我可以添加新的路线，这些路线也很好用。模型绑定在引导函数的RouteServiceProvider.php类中定义：

public function boot(Router $router)
{
    parent::boot($router);
    // Route model binding
    $router->model('project', 'resolved7'Project');
    $router->model('user', 'resolved7'User');
    $router->model('node', 'resolved7'Node');
    $router->model('task', 'resolved7'Task');
    $router->model('io', 'resolved7'Io');
}

我唯一能做到这一点的方法是将路线更改为：

Route::get('projects_1/{project}/nodes/{node}/tasks/create', 
['uses' => 'TaskController@taskCreateShow']);

我看了.htaccess文件，看起来不错。有人可能知道是什么导致了这种情况的发生吗？我感谢任何帮助或建议。谢谢

*edit：这是routes.php文件：
