Canopy 1.4.1外壳突然卡住

Question

我已经用了一段时间了，我从来没有遇到过问题。今天我启动了这个程序，无论我做什么，控制台要么什么都不给我，要么像这样：

IOError                                   Traceback (most recent call last)

     46         while stream.getsockopt(zmq.EVENTS) & zmq.POLLIN:
     47             with context():

        global kernel.do_one_iteration = undefined

        global IOError = undefined
    493     
    494     def _rebuild_io_state(self):

IOError: Stream is closed

即使我只是做了一些简单的事情：

a = 1

它卡住了，它给了我以前的IOError。请帮帮我，我需要它工作！

谢谢，卢卡

当您说您执行了步骤3和4的完全卸载时，您是指此链接吗？：https://support.enthought.com/entries/23580651-Uninstalling-and-resetting-Canopy

如果是这样，您仍然得到错误，那么您可能已经创建了一个与系统库模块同名的python文件，因此干扰了python的启动。在hour主目录中查找，或者在PYTHONPATH上的每个目录中查找。

另外:检查您的环境(在终端中键入env )是否有任何与python相关的可能干扰的环境变量，因为您的“昨天的最后一件事”安装可能会破坏您系统上的某些东西。
