我试过但我不太好

public function up()
        {
            Schema::create('users',function($table){
                $table->increments('id');
                $table->string('name',30);
                $table->string('phone',11);
                $table->integer('age');
                $table->string('email',50);
                $table->string('marry_status',10);
                $table->integer('address_id');

                $table->integer('points_id');

                $table->timestamps();   
            });
            Schema::table('users',function($table){
                $table->foreign('points_id')->references('id')->on('address')->onDelete('cascade')->onUpdate('cascade');
                $table->foreign('address_id')->references('id')->on('address')->onDelete('cascade')->onUpdate('cascade');
            });

        }

Answer 1

您的语法有误。您正在使用 reference() 方法，但正确的方法是 references()。修复它，我想一切都会好的。
