不明确的制表符补全在 Windows 上的 iPython 中不起作用
我在安装了 pyreadline 的 Windows 7 x64 上运行 IPython。如果我开始一个新会话并输入：
import numpy
nu<TAB>
然后 nu 自动完成为 numpy。但是，如果我开始一个新会话并尝试以下操作：
import numpy
n<TAB>
那么什么也不会发生。我希望它能够循环所有可能的完成。我目前正在使用开箱即用的配置，我是否需要更改设置以启用不明确的选项卡完成功能，或者我只是运气不好？
编辑： 为了解决 ma3204 的评论，这里有另一个例子（从新的 ipython 会话开始）：
[In 1]: value1 = 5
[In 2]: value2 = 6
[In 3]: va<TAB> ... nothing happens
[In 3]: va<Ctrl + l>
vars value2 value1
[In 3]: val<TAB> ... completes to 'value'
[In 3]: value
[In 3]: value<Ctrl + l>
value2 value1
[In 3]: value
当我在上面输入 va 时，我希望每次按 Tab 键都会循环浏览 value1、value2、vars、value1、value2 等。
I am running IPython on Windows 7 x64 with pyreadline installed. If I start a new session and type:
import numpy
nu<TAB>
Then nu autocompletes to numpy. However, if I start a new session and try this:
import numpy
n<TAB>
Then nothing happens. I would expect it to cycle through all of the possible completions. I'm currently using out of the box config, do I need to change a setting to enable ambiguous tab completion or am I just out of luck?
EDIT:
To address the comment from ma3204, here is another example (start with fresh ipython session):
[In 1]: value1 = 5
[In 2]: value2 = 6
[In 3]: va<TAB> ... nothing happens
[In 3]: va<Ctrl + l>
vars value2 value1
[In 3]: val<TAB> ... completes to 'value'
[In 3]: value
[In 3]: value<Ctrl + l>
value2 value1
[In 3]: value
When I type va<TAB> above I would expect each tab press to cycle through value1, value2, vars, value1, value2, etc.

您必须将 pyreadline 的配置文件复制到您的 HOME 文件夹（C:\Users\<用户名>）。
打开命令行并执行：
You have to copy config file for pyreadline to your HOME folder (C:\Users\< username >).
Open Command line and execute that:
刚刚安装了python 2.6和numpy、ipython等。我也对此感到恼火。在我的其他安装较旧的计算机上它可以工作。我经常使用完成列表来查看哪些命令可用，因此当它不起作用时我会感到沮丧。
编辑：发现你可以用 CTRL-l 来获取它。查看 ipythonrc ，它应该像我习惯的那样工作，但不是。但 CTRL-l 可以工作。将看看它是否会重新启动。好像记得我以前也遇到过类似的问题，但过了一段时间就解决了。
Just installed python 2.6 and numpy, ipython and so on. I am also annoyed of this. On my other computers with older installations it works. I use the completions list very much to see what commands are available so I feel frustrated when it doesn't work.
EDIT: Found that you can get it with CTRL-l. Looked in ipythonrc and it should work like I am used to but not. The CTRL-l work though. Will see if it kicks back on. Seem to remember that I had similar trouble before but it worked after some time.
