在route.php中添加代码：

use think\Route;
Route::get('/',function (){
    return 'hello world';
});

在浏览器中输入http://localhost/tp5-git/public/index.php，报错：

[8192] ErrorException in route.php line 13
Non-static method think\Route::get() should not be called statically

use think\Route;
Route::get('/',function (){
    return 'hello world';
});
Route::get('think', function () {
    return 'hello,ThinkPHP5!';
});

Route::get('hello/:name', 'index/hello');

return [

解决方法是：注释掉“use think\Route;”即可。

成功界面：

思考：观察route.php中自带的代码，发现他们都没有“use think\Route;”，在网上搜索没有找到明确的解决方案，但仔细思考，可能就是“use think\Route;”的问题，注释掉果真成功了。
