Question

我在 Raspberry Pi 2 Model B上运行 python-3.2 中的脚本

线程看起来像这样：

myThread = threading.Thread(target=someFunction, args=(arg1,arg2,arg3),
           daemon=True)
myThread.start()

每次调用此线程。此错误被触发：

TypeError: __init__() got an unexpected keyword argument 'daemon'

我知道 Debian Wheezy Version 7.10 没有 Python-3.4 稳定版本因此我必须使用 python 3.2

具有讽刺意味的是，Python 3.2 Documentation表明daemon是一个可用的布尔值。

这是什么故障，我该如何解决？

守护程序参数已在版本3.3 see中添加。在先前版本中设置标志的工作方式如下：

线程不能在python3.2中守护进程吗？
