Answer 1

$user是一个字符串。将您的代码更改为此：

public function update(Request $request)
{
    $user =  Auth::user();
    $user->name = $request->input('name');
    $user->save();
}

Answer 2

您可以使用

public function update(Request $request)
{
    $user_id =  Auth::user()->id ;
    $user=User::find($user_id);
    $user->input($request->input('name'));
    $user->save;
}

OR

public function update(Request $request)
{
    $user =  Auth::user();
    $user->name = $request->input('name');
    $user->save();
}

在字符串上调用成员函数update（）
