ipython在启动时提供attributeerror

Question

当我发射时

ipython

我明白了

AttributeError: '_NamespacePath' object has no attribute 'sort'

我无能为力。我试图pip3卸载东西，但我得到了相同的消息（错误堆栈略有不同）。我能做什么？我应该烧掉电脑然后重新启动一台新的吗？python工作得很好。

完整堆栈：

它可能是您的python版本（假设您在v3.x上），也可能是缺少的dependencie。

尝试卸载ipython

pip uninstall ipython

然后升级您的pip和setuptool版本（它们可能不是最新版本，从而导致问题）：

pip install --upgrade pip
pip install --upgrade setuptools

再次运行ipython的安装，或者使用：

• 使用pip

pip install ipython

• 或轻松安装：

easy_install ipython

• 或使用iptyhon安装文档中的其他程序从源代码处获取

在我这边，我经常使用蟒蛇，它已经集成和工作了大多数依赖和包。所以你可以尝试一下，如果上面的不适合你。
