Good news guys, it works! Thanks very much for all of your advice. I first installed the new version as Jeff suggested and then installed realine by ./pip as Elisabeth and Casey said. I did followed the instruction before I updated yt to install readline under the right directory but and it said that readline was installed successfully but still didn't work. Now everything works:)<br>

Hello everyone,<br>
<br>
I'm Chao, just started to learn how to use yt and python.<br>
<br>
After I installed yt following the instruction in the main page, when I<br>
invoke iyt<br>
or ipython, waring of "Readline Services not available on this platform"<br>
and "The<br>
auto-indent feature requires the readline library' came out.<br>
<br>
I'm using Ubuntu11.10 shipped with python2.7.2+ and when I run this<br>
version, readline<br>
is available. But I was installing yt, it seems that python2.7.1 was<br>
installed along with yt,<br>
and consequently ipython and iyt was built upon python2.7.1. I tried<br>
python2.7.1 and<br>
showed that the readline is not available, and so does iyt and ipython. I<br>
don't know whether<br>
multiple versions of python caused this problem and I don't know how to<br>
solve it. Can<br>
anyone give some guidance? I'm new to linux and I apologize if this problem<br>
is<br>
too obvious to experienced users. But I haven't found effective solution on<br>
google.<br>
<br>
Thanks,<br>

Hi Chao,<br>
<br>
Welcome to yt! My apologies for this. By using the install script, you<br>
get a complete python environment that is completely isolated from<br>
your system. This means that you can be assured if something goes<br>
wrong with the yt install, you haven't touched your system python at<br>
all. As it happens, we just fixed this problem a few days ago, and it<br>
hasn't propagated to the stable branch yet. Could you try to install<br>
from the development branch, by downloading the install script from<br>
<br>
$ wget <a href="http://hg.yt-project.org/yt/raw/yt/doc/install_script.sh" target="_blank">http://hg.yt-project.org/yt/raw/yt/doc/install_script.sh</a><br>
$ bash install_script.sh<br>
<br>
instead? This should fix your problem straight away. As it happens,<br>
Python 2.7.1 won't work on Ubuntu 11.10 very well at all. In the mean<br>
time, I will migrate the updated install script from the development<br>
branch to the stable branch.<br>
<br>
You can just delete the entire yt directory that you already<br>
installed, and it will not interfere with anything.<br>
<br>
Again, welcome to yt!<br>
<br>
Jeff<br>

Hi Chao,<br>
<br>
In case Jeff's solution doesn't work, try installing readline using "pip" which is part of the yt package:<br>
<br>
~/yt/bin/pip install readline<br>
<br>
For some reason, I get similar problems with readline even though it's blatantly on the system already.<br>

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

Hi Chao.<br>
<br>
Are you certain that this command installed readline to your yt python<br>
environment? I'm not certain how pip determines which python site-packages<br>
to install to, but I think it depends on PYTHONPATH/PYTHONHOME. Anyone know<br>
about this?<br>
<br>
I recommend...<br>
<br>
$ source /path/to/yt/bin/activate<br>
$ pip install readline<br>
<br>
You can check that it installed to the right place by navigating to<br>
/path/to/yt/lib/python2.7/site-packages/ and seeing if the readline package<br>
is there. If it is there and still doesn't work, then this is really<br>
weird...<br>
<br>
Either way, we should fix this line of the docs because it assumes yt is<br>
installed to ~/yt and it doesn't say anything about setting env vars or<br>
using activate. Something like /path/to/yt?<br>
<br>
Best,<br>
Casey<br>
