在Laravel中，View不会返回任何内容
[英]View doesn't return anything in Laravel
问题描述
I just started to learn the laravel framework and have a strange situation here. 
我刚刚开始学习laravel框架并且在这里有一个奇怪的情况。
First of all in my web.php I have code like: 首先在我的web.php我有以下代码：
<?php
Route::get('/', function () {
return view('welcome');
});
Route::get('users', ['uses' => 'UsersController@index']);
In my UsersController.php file I have code like: 在我的UsersController.php文件中，我有以下代码：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class UsersController extends Controller
{
public function index(){
return view('users.index');
}
}
I have a file named index.blade.php in directory views/users that has the same content as the default welcome.blade.php . 我在目录views/users中有一个名为index.blade.php的文件，其内容与默认的welcome.blade.php相同。 But when I try to return view('users.index'); 但是当我尝试return view('users.index'); there is no result (no error, or text) but when I try to return view('welcome'); 没有结果（没有错误或文本）但是当我尝试return view('welcome'); it works just fine. 它工作得很好。
The directory and the file truly exists. 目录和文件确实存在。 I'm using Macbook Pro. 我正在使用Macbook Pro。
welcome.blade.php and the /users/index.blade.php content (default welcome page): welcome.blade.php和/users/index.blade.php内容（默认欢迎页面）：

The problem was with file permissions. 问题出在文件权限上。 Change all the files to readable and writeable and it will be okay. 将所有文件更改为可读和可写，这样就可以了。
On macbook you can do it by entering this command in terminal: 在macbook上，您可以通过在终端中输入以下命令来执行此操作：
chmod -R 777 /way/to/the/path/*

On apache check the logs, see what's wrong:
/var/log/apache2/error.log在apache上检查日志，看看有什么问题： /var/log/apache2/error.logGive 755 perms to bootstrap/cache/ and /storage folder.
给bootstrap / cache /和/ storage文件夹提供755 perms。 sudo chmod -R 755 storage bootstrap/cacheGenerate encryptions key:
php artisan key:generate生成加密密钥： php artisan key:generateCheck your /etc/hosts file, make sure it's pointing to right virtual host.
检查/ etc / hosts文件，确保它指向正确的虚拟主机。 Restart apache:
sudo service apache2 restart重启apache： sudo service apache2 restart
