Spyder does not autocomplete local variables

问题:

I'm having a problem getting my local variables autocompleted. This is a very basic functionality which I'm sure it should support. When I'm starting to write a variable name which was already declared, and press TAB (this is the default shortcut), I get nothing. Is this a bug?

回答1:

(Spyder dev here) Spyder does complete local variables but to have this functionality you need to install a library called rope. You can do it by running this command in a terminal

pip install rope 

If you use Python 3 this command needs to be

pip install rope_py3k 

Besides, code completion on the Editor works now with both Ctrl+Space and with Tab.

Edit: Updated answer for the Spyder version 2.3.0.

Idoda, I made a little guide to install Python for scientific computing on Ubuntu or Debian from their repositories. I tested correctly using Python 3 on Ubuntu 14.04 LTS.

It summarizes as follows. First, install the interpreter and the package manager:

sudo apt-get install python3 python3-pip  

Now install the Spyder's IDE:

sudo apt-get install spyder3 

Thanks to Carlos Cordoba's advice, if you want to enjoy the autocomplete execute:

sudo pip3 install rope_py3k 

Finally, open Spider and check if the autocomplete works rightly.

In my case, with the command conda install spyder, the installation process prompted me with the following...

The following NEW packages will be INSTALLED:  rope:   0.10.5-py36_0 conda-forge spyder: 3.1.4-py36_0  conda-forge  Proceed ([y]/n)? y 

I want to point out that my anaconda installation is for python 3. After this auto-completion was working. I'm utilizing OS X El Capitan.

Another hint:

If you want to customize the shortcut (for example, your 'ctrl+space' is already occupied), try

Tools--Preferences--Keyboard shortcuts--code completion 

you can change it to whatever you want

回答5:

Usually, ctrl+space is set to code completion in Tools -> Preferences -> Keyboard shortcuts -> code completion We have the option to change it to another shortcut.

回答6:

I just reinstalled anaconda and auto completion working now.

Steps that I followed:

1> Uninstall Anaconda from control panel

2> Restart Computer

3> Download and install anconda from [here][1]

4> Restart again before it you start anaconda.

5> done.
