    120     kwargs : various, optional

Oops, ipython crashed. We do our best to make it stable, but...

A crash report was automatically generated with the following information:
  - A verbatim copy of the crash traceback.
  - A copy of your input history during this session.
  - Data on your current ipython configuration.

It was left in the file named:
        '/home/local/ANT/dylone/.ipython/Crash_report_ipython.txt'
If you can email this file to the developers, the information in it will help
them in understanding and correcting the problem.

You can mail it to: The IPython Development Team at [email protected]
with the subject 'ipython Crash Report'.

If you want to do it now, the following command will work (under Unix):
mail -s 'ipython Crash Report' [email protected] < /home/local/ANT/dylone/.ipython/Crash_report_ipython.txt

In your email, please also include information about:
- The operating system under which the crash happened: Linux, macOS, Windows,
  other, and which exact version (for example: Ubuntu 16.04.3, macOS 10.13.2,
  Windows 10 Pro), and whether it is 32-bit or 64-bit;
- How ipython was installed: using pip or conda, from GitHub, as part of
  a Docker container, or other, providing more detail if possible;
- How to reproduce the crash: what exact sequence of instructions can one
  input to get the same crash? Ideally, find a minimal yet complete sequence
  of instructions that yields the crash.

To ensure accurate tracking of this issue, please file a report about it at:
https://github.com/ipython/ipython/issues

所以
ipython>=7.0.0使用prompt_toolkit>=2.0.0,<2.1.0
ipython<7.0.0使用prompt_toolkit>=1.0.15,<2.0.0

在hint_toolkit <2.0.0中， invalidation_hash总是返回str或int ，但是在最后一个版本中，它可能还会返回tuple 。

作为解决方法，我使用以下方法：

diff --git a/powerline/renderers/ipython/since_5.py b/powerline/renderers/ipython/since_5.py

但是，我不确定是否值得为此创建公关。 它看起来并不整洁。

创建一个带有适当修复程序的since_7.py类型文件是否值得？

能做到吗？ 这使我无法使用电力线。

上面提到的修复程序可使电源线不崩溃，但不能修复它。 如图所示，显示的提示很难看，在应该改变颜色的任何地方显示“＆”。

&字符似乎是不间断的空格（ \xa0 ）; 通过主题配置禁用它们会将它们替换为普通空格。 但是，颜色似乎仍然没有变化，并且所有内容都具有透明背景，并且#00005f作为前景色。

我可以确认当前版本的iPython（在本例中为7.4）电源线是否断开。
@Zebradil建议的修复程序使iPython至少可以再次使用（谢谢！），但是-
如前所述-用＆代替颜色来装饰提示。

我在IPython 7.3.0中遇到此问题。 必须停止扩展才能使用IPython。

什么时候修好~~~

随时继续。 从@Zebradil的补丁开始，看看
为什么将iPython提示符减少为＆s。

您会帮助很多受此错误影响的人。

“用＆代替颜色装饰提示”的作用是什么？ 看起来像？ 我使用补丁，它看起来像下面：

什么都没有 ＆。

感谢您进一步调查此问题！

什么都没有 ＆。

在您的情况下，“＆”被替换为“ _”-有趣的是，
似乎取决于您使用的系统。

这是Kubuntu 18.04下提示的外观：

&字符似乎是不间断的空格（ \xa0 ）; 通过主题配置禁用它们会将它们替换为普通空格。 但是，颜色似乎仍然没有变化，并且所有内容都具有透明背景，并且#00005f作为前景色。

我仍然认为有关&的问题是另一个问题，与颜色无关。

在您的情况下，“＆”被替换为“ _”-有趣的是，
似乎取决于您使用的系统。

它不依赖于系统，而是版本
提示工具包：我从2.0.7升级到2.0.9
现在所有的“＆”都是“ _”。

那是/是2.0.8中的新功能：

• 在不间断空格下加下划线，而不是将其渲染为“＆”。

@acgtyrant是否已安装2.0.9？

对于颜色，似乎忽略了Token.Generic.Prompt之后的任何内容： https :

据我了解，对于每个突出显示组，都会创建一个新的令牌类型，并且应该在renderers / ipython / since_5.py中定义的自定义DynamicStyle会创建相应的样式。 但是，似乎没有调用get_attrs_for_token或get_token_to_attributes_dict ； 查看https://github.com/prompt-toolkit/python-prompt-toolkit/commit/c32f3783a76e6b72d53acda0b6c4a15ef13bed3b会发现，alert_toolkit不再使用get_attrs_for_token ，而是使用get_attrs_for_style_str 。

看来我对颜色问题有（非常棘手的）解决方案：在hl记录所有使用的突出显示，将它们转换为hint_toolkit-style格式对，并将这些新对附加到通过实现已生成的样式规则中

    <strong i="7">@property</strong>
    def style_rules(self):

在class PowerlinePromptStyle(DynamicStyle): 。

如您所见，我仍然需要清理代码，但是它似乎可以工作。

@ PH111P-太好了，感谢您潜入兔子洞！

因此，这两个新问题（缺少的颜色和“＆” /“ _”）都是由
提示工具包升级到版本2？

因此，这两个新问题（缺少的颜色和“＆” /“ _”）都是由
提示工具包升级到版本2？

我想是的，是的。

也许指南“升级到hint_toolkit 2.0”会有所帮助
因为它说明了需要的更改：

https://python-prompt-toolkit.readthedocs.io/zh-CN/master/pages/upgrading.html#pygments -styles-and-token

可以在这里找到颜色修复的实现https://github.com/PH111P/powerline/blob/develop/powerline/renderers/ipython/since_7.py
可以通过在配置文件中禁用它们来解决nbsp的问题（通过设置"use_non_breaking_spaces": false ）。

如果碰巧有时间，我可能会写一个请求请求。

@GHPS我安装了2.0.8-1。

可以在此处找到颜色修复的实现

太好了-您已将其修复。 iPython和Powerline再次可用！
感谢您抽出宝贵的时间整理出来...

您是否有机会复活VI模式指示器
也一样目前不见了...

我添加了颜色修复和配置，但是我的IPython中仍然有_ ，我不知道为什么。

我添加了颜色修复和配置，但是我的IPython中仍然有_ ，我不知道为什么。

抱歉，确实不能为此使用配置文件（提到的标志仅在全局主题级别上起作用；就我个人而言，我在源代码中全局禁用了nbsp，但这不应该成为解决方法）； 似乎为了修复nbsp，需要更改ipython渲染器，特别是在class IPythonPygmentsRenderer(IPythonRenderer):添加以下内容应该可以解决此问题。
（这一次我实际上测试了该解决方法，再次对另一件事没有真正起作用感到抱歉；另请参见https://github.com/PH111P/powerline/blob/develop/powerline/renderers/ipython/since_7.py）

    def __init__(self, **kwargs):
        super(IPythonPygmentsRenderer, self).__init__(**kwargs)
        self.character_translations[ord(' ')] = ' '

您是否有机会复活VI模式指示器
也一样目前不见了...

似乎根本就没有该功能的细分市场。 但是，以下内容似乎可以正常工作，可以随时将其转换为完整的段（大多数代码从实际的ipython实现中被无耻地窃取了：https://github.com/ipython/ipython/blob/4f901de17aff2132365fc3741fc5b4b8b9a98dc6 /IPython/terminal/prompts.py#L16）：

<strong i="9">@requires_segment_info</strong>
def vi_mode(pl, segment_info):
    ipython = segment_info['ipython']._shell
    if (getattr(ipython.pt_app, 'editing_mode', None) == 'VI'
            and ipython.prompt_includes_vi_mode):
        return str(ipython.pt_app.app.vi_state.input_mode)[3:6]
    else:
        return None

编辑：虽然它似乎确实显示了当前模式，但是它似乎并没有真正更新：/。 我必须承认我并没有在ipython中真正使用vi模式，因此我无法真正测试它。
编辑2 ：通过更新绑定进行了修复： https :

@ PH111P-太棒了！ 做得好！

在承认Philip（aka @ PH111P ）的出色工作的同时，我想提出一个问题，是否可以对--simple-prompt选项做任何事情：

公关似乎已经无人值守了一段时间。 有计划更新吗？

据我所知，所有内容（ --simple-prompt除外）似乎都可以正常工作，所以我不确定您指的是@teracamo。 （实际上，PR尚未合并，但这似乎与＃2012有关；严格来说，PR仍缺乏测试，但正如我所说，它应该已经可以使用了）

哦，我只是指是否有计划合并此PR，因为当前版本不适用于ipython> = 7.0。
我还没有尝试过PR，所以我不能对--simple-prompt选项说什么，但是如果没有任何合并计划，我会做。

@alabamagan https://github.com/powerline/powerline/pull/2048怎么样？

在发布更改之前，请先检出develop分支以获取更改。 它可能不如master稳定，但比根本无法使用电力线提示要好：

pip install --user 'git+https://github.com/powerline/powerline.git@develop#powerline'

然后，在您的ipython配置中，将since_5更改since_7 ，如下所示：

from powerline.bindings.ipython.since_7 import PowerlinePrompts
c.TerminalInteractiveShell.simple_prompt = False
c.TerminalInteractiveShell.prompts_class = PowerlinePrompts

他们被释放多久？

也许需要一个新版本。
最新版本是2年前。

感谢您发布新版本。 但是，在将电力线升级到2.8-1之后，我仍然遇到此错误。 我不知道为什么。

/usr/lib/python3.8/site-packages/powerline/renderers/ipython/since_7.py已经存在。

您应该添加

from powerline.bindings.ipython.since_7 import PowerlinePrompts
c.TerminalInteractiveShell.prompts_class = PowerlinePrompts

配置。 https://github.com/powerline/powerline/blob/develop/docs/source/usage/other.rst
该文档未更新。

我将其添加到配置中，现在可以使用了。 谢谢！

感谢您发布新版本。 但是，在将电力线升级到2.8-1之后，我仍然遇到此错误。 我不知道为什么。

该文档未更新。

确实，这些文档已经很老了（最后一个版本是从1.5年前开始的）。 但是，自动构建无法正常工作，我缺乏检查/更改有关配置的权限，对不起。

@ PH111P请将新版本也推送到PyPI。 它仍然只有2.7版本...

可悲的是，我认为我没有访问权限。
同时，您可以尝试pip install git+https://github.com/powerline/powerline.git@develop 。
