Answer 1

没有代码，我不得不猜测这一点。属性错误意味着您正在尝试访问不存在的对象的属性。

例如，如果我有一个名为矩形的对象。它有两个属性宽度和长度;现在如果我尝试使用这个矩形并尝试访问一个名为radius的属性，它将产生一个错误，因为该对象的属性不存在。

File "/var/www/comunidadsm/env/local/lib/python2.7/site-packages/allspeak/reader.py", line 79, in _extract_locales
for locale, trans in data.items()
AttributeError: 'NoneType' object has no attribute 'items'

Perhaps changing that line to:
for locale,trans in (data.items() if data else [])

Not sure if that syntax will work right here, but it is an attempt

如果数据不是None则传递空列表，跳过循环。可能不是最好的解决方案，但你可以找出结果在它之后。

为什么这段代码会产生这个错误？
