laravel 路由失败

在laravel 5.4

Route::group(['prefix' => 'posts'],function(){    Route::get('/','PostController@index');    Route::put('/delete','PostController@delete');    Route::get('/{post}','PostController@show');    Route::any('/create','PostController@create');});

得到某位大神指导
由于在create 之前有｛｝ 所以 laravel 会把create 换成｛create｝

路由访问检测是从上到下，当检测到｛｝时后面的会替换成含有｛｝

解决方法
把含有｛｝放后面，要么加个路由正则，限制只接收数字参数

Route::group(['prefix' => 'posts'],function(){    Route::get('/','PostController@index');    Route::put('/delete','PostController@delete');    Route::any('/create','PostController@create');    Route::get('/{post}','PostController@show');});
