我该如何解决这个问题？我有 Python 2.7 版

【问题讨论】：

IPython Notebook 需要 tornado >= 2.1.0
我假设你有 Windows 操作系统。你关注过这些installation steps in Windows吗？

【解决方案1】：

您需要安装 tornado 网络服务器。假设您已安装 pip 并在您的路径上：

pip 安装龙卷风

【讨论】：

在windows上安装pip请看这里：stackoverflow.com/questions/4750806/…
从here下载tornado安装程序，然后双击。
您需要打开 Visual Studio 命令提示符或运行 vcvarsall.bat（在您的 Visual Studio 文件夹中）或手动设置必要的环境变量。完成后，运行 pip。
pip install tornado --upgrade
如果你在 linux 上，并且你已经安装了你的发行版的 python-tornado 包，也可以这样做：sudo apt-get remove python-tornado。
