原本可运行的工程 什么也没干过一段时间无法运行了? 还是macos系统更新导致的

1:Flutter 报错 没有运行模拟器 连接了iphone6s锁屏 爆如上错误 开平后 还是报如上错误 模拟器可正常运行
xxx.py都是python的错误 xxx.py就是错误日志里面的"/tmp/9E74ECF2-A95A-4878-9E2A-5E8E1AB62979/fruitstrap_07900db410d645ac62a62d3ccb2eb4d1fa92e75c.py"

'NoneType' object has no attribute 'modules' 
'NoneType' object has no attribute 'process' 

分析怀疑是因为MacOS系统进行了大的版本更新导致的===lldb.target===变更导致的 升级xcode和flutter后解决

更新前的错误的xx.py

    process = lldb.target.ConnectRemote(listener, connect_url, None, error)

更新后的正确的xx.py

    process = debugger.GetSelectedTarget().ConnectRemote(listener, connect_url, None, error)

这种情况说明MacOS和flutter最好同步更新
