小编use*_*126的帖子

我有这个简单的代码来使事情变得更简单。

from multiprocessing import Process
def abc():
    print("HI")
    print(a)

a = 4
p = Process(target = abc)
p.start()

它在 ubuntu (Python 3.8.5) 中运行得很好，并提供输出：

HI
4

但是，它在spyder（Python 3.9.5）“AttributeError：无法在<模块' main '（内置）>上获取属性'abc'”和macOS（Python 3.8.10，我也尝试了其他版本）中失败并失败）CLI“运行时错误”。

间谍错误：
