`ipython`选项卡自动完成功能不适用于导入的模块

Tab completion on IPython seems not to be working. For example,

IPython上的标签完成似乎不起作用。例如，

import numpy
numpy.<tab>

simply adds a tab.

只需添加一个标签。

import numpy
num<tab>

just adds a tab, too. Could you please suggest some possible causes for this problem? I am running Windows 7 and Python 2.6.5.

只是添加一个标签。你能否提出一些可能导致这个问题的原因？我正在运行Windows 7和Python 2.6.5。

Be sure you have installed the pyreadline library. It is needed for tab completion and other IPython functions - in Windows it doesn't come with the IPython package and you have to install it separately -

确保已安装pyreadline库。选项卡完成和其他IPython功能需要它 - 在Windows中它没有附带IPython包，你必须单独安装它 -

> pip install pyreadline

Your ipythonrc file may be out of date. Try running

您的ipythonrc文件可能已过期。试试跑步

ipython -upgrade

#3

pip told me I had pyreadline version 1.7.1 installed

pip告诉我，我安装了pyreadline 1.7.1版

C:\Users\me>pip freeze | grep readline
pyreadline==1.7.1

Upgrading pyreadline fixed it for me:

升级pyreadline为我修复了它：

C:\Users\me>pip install --upgrade pyreadline

C:\Users\me>pip freeze | grep readline
pyreadline==2.0

#4

The classic 'have you tried turning it off and on again' worked for me.

经典的“你试过把它关掉再打开”对我有用。

pip uninstall ipython
pip install ipython

#5

As of right now, on a OSX, pip installed ipython doesn't give tab completion, pyreadline release.py is busted .. what WFM:

截至目前，在OSX上，pip安装的ipython没有给标签完成，pyreadline release.py被破坏..什么是WFM：

easy_install ipython readline

YMMV.

因人而异。

Its basicly easy_install readline than discover where the readline egg got installed and edit the ipython bin script to use this readline:

它基本上是easy_install readline，而不是发现readline egg安装的位置，并编辑ipython bin脚本以使用此readline：

Install the "official" readline: easy_install readline
安装“官方”readline：easy_install readline
Discover where it is. Look at /Library/Python/site-packages/readline-*.egg or in your Virtualenv counterpart
发现它的位置。看看/Library/Python/site-packages/readline-*.egg或你的Virtualenv对应物
Discover where ipython bin is: which ipython
发现ipython bin的位置：ipython
Add ONE LINE to this file, adding the readline egg path right after import sys line.
在此文件中添加一行，在导入sys行后立即添加readline egg路径。

My virtualenved ipython bin script got working as follow:

我的虚拟ipython bin脚本开始工作如下：

#!/Users/alanjds/src/git/cervejeiras/venv/cervejeiras-lfs/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'ipython==0.13.1','console_scripts','ipython'
__requires__ = 'ipython==0.13.1'
import sys

### ONLY LINE ADDED:
sys.path.insert(0, '/Users/alanjds/src/git/cervejeiras/venv/cervejeiras-lfs/lib/python2.6/site-packages/readline-6.2.4.1-py2.6-macosx-10.6-fat.egg')
####

from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('ipython==0.13.1', 'console_scripts', 'ipython')()
    )

I realize this is a really old question, but none of the answers above worked for me (And this is the first hit you get when you google a question of this nature).

我意识到这是一个非常古老的问题，但上面的答案都没有对我有用（这是你在谷歌提出这种性质的问题时得到的第一个打击）。

I should mention that this is NOT exclusive to windows, I had the problem running CentOS 6.5 and Python 2.7

我应该提到这不是Windows独有的，我遇到运行CentOS 6.5和Python 2.7的问题

Here is what I did:

这是我做的：

apt-get/yum install ncurses-devel
#If you want history in iPython:
apt-get/yum install sqlite-devel
easy_install ipython readline
ipython

In [1]: from 
Display all 391 possibilities? (y or n)

If you don't have the -devel packages, your install will fail when it comes time to link them and build the eggs.. Hope this helps others!

如果您没有-devel软件包，那么当需要链接它们并构建鸡蛋时，您的安装将会失败。希望这有助于其他人！

Pyreadline is needed by ipython. Install pyreadline. This was done in Windows 7. Get pyreadline zip, pyreadline-master.zip, unzip. In powershell change directory into uzipped pyreadline, make sure python is set in Path, and enter commandpython setup.py install This will intall pyreadline in C:\Python27\Lib\site-packages

ipython需要Pyreadline。安装pyreadline。这是在Windows 7中完成的。获取pyreadline zip，pyreadline-master.zip，解压缩。在powershell中将目录更改为uzipped pyreadline，确保在Path中设置python，然后输入commandpython setup.py install这将在C：\ Python27 \ Lib \ site-packages中输入pyreadline

I had this problem and knew that I had the pip installed for the module I was looking for. Performing $ ipython --init solved the problem for me.

我有这个问题，知道我已经为我正在寻找的模块安装了点子。执行$ ipython --init为我解决了这个问题。

I had to mv ~/.ipython{,.bak} in my case.

在我的情况下，我不得不使用mv~ / .ipython {，。bak}。

If you use Jupyter notebook and you still did get Tab auto-complete working after you tried all the steps suggested in the post here, you might want to check if you are trying to use the Tab auto-completion within a function definition. Ifyour import statements are part of the function such as below, you will not get the Tab auto-completion. You need to put the import statements outside the function and also execute them once before asking for auto-completion on the packages.

如果您使用Jupyter笔记本，并且在尝试了此处帖子中建议的所有步骤后仍然可以使Tab自动完成工作，您可能需要检查是否尝试在函数定义中使用Tab自动完成。如果您的import语句是函数的一部分，如下所示，您将无法获得Tab自动完成。您需要将import语句放在函数外部，并在要求对包进行自动完成之前执行它们一次。

def myfunction():
    import pandas as pd
    import numpy as np

    a = pd.DataFrame(np.random.normal(1,3, (4,4))
    return a
