刚开始学习，随便找了个代码运行，结果出错不清楚是怎么回事，求助。
代码：
import cocos
class HelloWorld(cocos.layer.Layer):
def __init__(self):
super(HelloWorld, self).__init__()
#创建标签
label = cocos.text.Label('你好',
font_name='Times New Roman',
font_size=32,
anchor_x='center',anchor_y='center')
width, height = cocos.director.director.get_window_size()
label.position = width // 2, height // 2
self.add(label)
if name == “main”:
cocos.director.director.init(width=1000, height=1000, caption=“Hellow World”)
hello_layer = HelloWorld()
mian_scene = cocos.scene.Scene(hello_layer)
cocos.director.director.run(mian_scene)
结果:
