我是 Python 新手，正在努力让 IPython（也是 numpy/scipy 包）在我的 Win7 机器上正常工作。我安装了 Python3.3，IDLE 工作，命令“ipython3”单独启动 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。

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

  • pexpect 不适用于 Python 3
  • pexpect 在 Windows 上不起作用

您应该卸载 pexpect ( pip uninstall pexpect)。如果您想要 Python 3 中的 pexpect 功能，那么您需要与 Python 3 兼容的 fork pexpect-u，但这不适用于 Windows。
