Question

I'm running Laravel 6 and PHP 7.2 and I'm getting this error:

Illuminate\\Contracts\\Container\\BindingResolutionException thrown with message "Target class [encrypter] does not exist."

Stacktrace:

Any idea what I need to fix?

Answer 1

如果您已将类组织到子文件夹中，请检查命名空间——它也应包含子文件夹。

Answer 2

将旧的加密器中间件复制到新创建的项目中间件文件夹。

Answer 3

You might get this exception when a middleware does not exist.

Let's consider the following route as example:

Route::get('/products/{productId}', 'ProductController@view')
     ->middleware('some_middleware');

If the middleware some_middleware is not implemented then you will get the exception Target class [some_middleware] does not exist .
