cwi*_*ind 4 python emacs ipython emacs25
我正在使用最新的 emacs25.1.1 和最新的 archlinux。
但是,当我编辑 python 脚本并使用 Ctrl-Enter 将其发送到 Inferior ipython 时,劣势 Python 向我显示了一个丑陋的杂乱代码终端指示符,例如:
Python 3.5.2 (default, Nov 7 2016, 11:31:36)

当在这个 Inferior python 中按 Enter 时,它显示:

我将 emacs 语言环境更改为:

使用命令 $"export LANGUAGE="en_US:en" && emacs"$,对解决凌乱的代码没有帮助。
我也在 emacs 中尝试 python-mode.et 或 elpy 包,都显示相同的混乱终端代码。
进一步?python2.7也试过了,不行:

是最新的 ipython 问题吗?
最后emacs中的消息粘贴在这里:

我使用了来自https://github.com/jorgenschaefer/elpy/issues/992#issuecomment-249165923 的推荐。简而言之 - 添加以下代码:
(setenv "IPY_TEST_SIMPLE_PROMPT" "1")到 emacs 配置文件中。
从输出和错误消息来看,由于某种原因,您的设置似乎没有处理 ipython 使用的 ansi 转义序列。假设您使用的是 pythong-mode,请确保您具有以下内容
(setq python-shell-interpreter "ipython"
python-shell-interpreter-args "-i")

为了消除初始化文件中的其他可能的设置,我会注释掉除上述之外的所有内容,然后重试。如果它有效,那么您的设置中存在一些问题,影响了 emacs 处理 ipython 输出的 ansi 控制序列的能力。如果仍然不起作用,那么您可能需要记录错误报告。
您还可以采取一些措施来解决该问题。
