IPython笔记本命令返回错误

Question

我是Python的新手，正在努力让IPython（也是numpy/scipy包）在我的Win7机器上正常工作。我已经安装了Python3.3，IDLE工作，单独的命令“ipython3”启动了ipython环境，但是我无法启动笔记本。我收到以下错误消息。帮助将不胜感激。

Answer 1

您已经在Windows上安装了Python 3上的pexpect。有两个问题：

• Pexpect的不Python的3
• Pexpect的工作在Windows

不起作用你应该卸载Pexpect的（pip uninstall pexpect）。如果你想在Python 3中使用pexpect功能，那么你需要与Python 3兼容的分支pexpect-u，但这不适用于Windows。
