Hello everyone,

I'm Chao, just started to learn how to use yt and python.

After I installed yt following the instruction in the main page, when I
invoke iyt
or ipython, waring of "Readline Services not available on this platform"
and "The
auto-indent feature requires the readline library' came out.

I'm using Ubuntu11.10 shipped with python2.7.2+ and when I run this
version, readline
is available. But I was installing yt, it seems that python2.7.1 was
installed along with yt,
and consequently ipython and iyt was built upon python2.7.1. I tried
python2.7.1 and
showed that the readline is not available, and so does iyt and ipython. I
don't know whether
multiple versions of python caused this problem and I don't know how to
solve it. Can
anyone give some guidance? I'm new to linux and I apologize if this problem
is
too obvious to experienced users. But I haven't found effective solution on
google.

Thanks,

Chao

Hi Chao,

Welcome to yt! My apologies for this. By using the install script, you
get a complete python environment that is completely isolated from
your system. This means that you can be assured if something goes
wrong with the yt install, you haven't touched your system python at
all. As it happens, we just fixed this problem a few days ago, and it
hasn't propagated to the stable branch yet. Could you try to install
from the development branch, by downloading the install script from

$ wget http://hg.yt-project.org/yt/raw/yt/doc/install_script.sh
$ bash install_script.sh

instead? This should fix your problem straight away. As it happens,
Python 2.7.1 won't work on Ubuntu 11.10 very well at all. In the mean
time, I will migrate the updated install script from the development
branch to the stable branch.

You can just delete the entire yt directory that you already
installed, and it will not interfere with anything.

Again, welcome to yt!

Jeff

Hi Chao,

In case Jeff's solution doesn't work, try installing readline using "pip" which is part of the yt package:

~/yt/bin/pip install readline

For some reason, I get similar problems with readline even though it's blatantly on the system already.

Hi all.

Yeah, I've seen this a few times. GNU readline is installed by default on
Ubuntu, so you should be good there (you have to get it yourself on Macs).
The python package readline is the Python interface for GNU readline, see
http://docs.python.org/library/readline.html. So, even if you have python
readline installed on the default (system) python site-packages, you need
to install it again in your yt site-packages.

Best,
Casey

Hi Chao.

Are you certain that this command installed readline to your yt python
environment? I'm not certain how pip determines which python site-packages
to install to, but I think it depends on PYTHONPATH/PYTHONHOME. Anyone know
about this?

I recommend...

$ source /path/to/yt/bin/activate
$ pip install readline

You can check that it installed to the right place by navigating to
/path/to/yt/lib/python2.7/site-packages/ and seeing if the readline package
is there. If it is there and still doesn't work, then this is really
weird...

Either way, we should fix this line of the docs because it assumes yt is
installed to ~/yt and it doesn't say anything about setting env vars or
using activate. Something like /path/to/yt?

Best,
Casey
