Vim编辑器 - zsh shell ipython magic％ed无法找到编辑器

问题描述

我正在尝试使用IPython中的％ed magic来使用vim作为编辑器。

I am trying to use the %ed magic in IPython to use vim as the editor.

• vim已安装


• ipython和ipython qtconsole都可以正常工作


• zsh是最新的，用我的oh-my-zsh安装更新

我将我的偏好导出到zsh

I exported my prefernce to zsh

$ echo "export EDITOR=/usr/bin/vim" >> ~/.zshrc

$ echo "export VISUAL=/usr/bin/vim" >> ~/.zshrc

但是，当我启动IPython然后调用％ed魔法时它会失败

However, when I launch IPython and then invoke the %ed magic it fails

In [1]: %ed
IPython will make a temporary file named: /tmp/ipython_edit_pu4Yql.py
Editing.../bin/sh: 1: mvim: not found
WARNING: Could not open editor

如何让它工作？

推荐答案

尝试使用IPython的配置文件配置作为指定编辑器的方法。为此：

Try using IPython's profile configuration as a means of specifying editor. To do this:

首先，生成默认配置文件：

Firstly, generate default configuration files:

$ ipython profile create

接下来，找到你的〜/ .ipython / profile_default / ..._ config.py 要编辑的文件。例如在IPython 2.4.1上，

Next, find your ~/.ipython/profile_default/..._config.py file to edit. For example on IPython 2.4.1,

$ vim ~/.ipython/profile_default/ipython_config.py

查找已注释掉的 .editor 设置，取消评论，以及将其设置为 vim 。例如在IPython 2.4.1中，这看起来像

Find the commented-out .editor setting, un-comment, and set it to vim. For example in IPython 2.4.1, this would look like

c.TerminalInteractiveShell.editor = 'vim'

您现在可以找到启动IPython的时间，％ed 它将调用vim：

You will now find when you start IPython, you can %ed and it will call up vim:

$ ipython
Python 2.7.11+ (default, Feb 22 2016, 16:38:42)
Type "copyright", "credits" or "license" for more information.

说明

man ipython ：

IPython使用存储的各种配置文件个人资料在
IPYTHONDIR内。要生成默认配置文件并启动
配置IPython，请执行'ipython profile create'，并编辑位于IPYTHONDIR / profile_default中的'* _config.py'文件。

IPython uses various configuration files stored in profiles within IPYTHONDIR. To generate the default configuration files and start configuring IPython, do 'ipython profile create', and edit '*_config.py' files located in IPYTHONDIR/profile_default.

$根据 man ipython ：

这是IPython存储其所有配置文件的位置。如果未定义IPYTHONDIR，则默认为$ HOME / .ipython。

This is the location where IPython stores all its configuration files. The default is $HOME/.ipython if IPYTHONDIR is not defined.

您可以使用 ipython locate 。

我也提到了版本，因为某些版本的设置看起来不同，因为2.4.1设置被称为：

Also I mention the version because settings seem different across some versions, for 2.4.1 the setting is called:

c.TerminalInteractiveShell.editor = ...

而在 IPython设置文本编辑器中给出的答案，此设置的名称不同：

Whereas in the answer given at IPython setting text editor, this setting was named differently:

c.IPythonWidget.editor = ...

由于版本之间似乎不同，因此在生成默认配置文件后，检查并查看它是如何在IPython版本中编写的，并采取相应措施。

Since it seems different between versions, after you generate the default configuration files, check and see how it is written in your IPython version, and act accordingly.
