AttributeError: ‘NoneType’ 对象没有属性 ‘split’ #1476

电脑电子

我正在使用 Ubuntu 16.04 – 64 位。
运行 bCNC 时出现此错误。

AttributeError: ‘NoneType’ 对象没有属性 ‘split’

请帮忙。

船尾

你运行的是哪个版本的 bCNC？
您使用的是 python2 还是 3？

小皮埃尔

@komputronika
您能否提供完整的错误堆栈？以及您的 python 和 bCNC 版本？
你有升级 pyserial 吗？

有同样的问题……我的设置

在 comportRefresh 中使用 pdb.stack_trace() 进行调试

你升级了pyserial吗？

低密度脂蛋白

bCNC 在笔记本电脑上运行。没有机器连接。
也许“无”来自禁用的蓝牙和 SD 卡读卡器。两者都在 USB 视图中显示感叹号。

低密度脂蛋白

pyserial==3.0.1 。. . . . 但在使用 dir(serial) 查找时没有 serial.Serial()

C:\Programme\Python\Python38-64\lib\site-packages\serial\ init .py
还有与 pySerial 同时安装的 v2.7.12。

低密度脂蛋白

已经用 try/except 包装了它作为快速解决…程序出现

低密度脂蛋白

(1) python -m pip install pyserial –upgrade 。. . 给了我 pyserial 3.5 与 bCNC
(2) python -m pip uninstall pyserial
(3) python -m pip install pyserial==3.0.1
建立了一个没有 try/except 解决方法的工作设置。

serial.Serial() 现在可用。
self.comportsGet() 返回 <generator object comports at 0x00000000142B8740> 与之前相比[('com1', None, None)]
