我建了一个user表，但是运行artisan migrate保存

就是这个表，运行命令后保存，我把sql语句复制出来，发现tinyInteger字段，默认被设置为主键，所以报错，求解

Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('username')->unique();
            $table->string('email')->unique();
            $table->string('telephone')->unique();
            $table->string('qq')->unique();
            $table->string('weixin')->unique();
            $table->string('sina')->unique();
            $table->string('password', 60);
            $table->string('name',50);
            $table->string('face');
            $table->tinyInteger('sex',1);
            $table->integer('age',3);
            $table->string('intro');
            $table->string('idcard');
            $table->string('bcard');
            $table->string('acard');
            $table->string('provincecode');
            $table->string('citycode');
            $table->string('areacode');
            $table->string('district _id');
            $table->string('address');
            $table->tinyInteger('is_check',1);
            $table->tinyInteger('is_look',1);
            $table->tinyInteger('status',1);
            $table->tinyInteger('type',1);
            $table->integer('login_counts',11);
            $table->timestamp('login_time');
            $table->string('login_ip');
            $table->timestamp('last_time');
            $table->string('last_ip');
            $table->decimal('total_money',11,2);
            $table->decimal('get_money',11,2);
            $table->decimal('could_money',11,2);
            $table->rememberToken();
            $table->timestamps();
        });
