[yt-users] installation issues with yt 2.5.5

[Luigi Iapichino]

Dear all,

while installing yt 2.5.5 I had to face some new issues. As you maybe  
remember, I have yt on a machine (SuperMUC in Garching, Germany) whose  
firewall permits only incoming SSH-connections. Running the install  
script there is rather annoying but, by making use of remote mounting  
through sshfs on my local PC, I have been able to always install yt.  
In this process, it is crucial that, whenever possible, the install  
script is organised in two distinct parts: a download part, run on my  
local PC, where I get all dependencies, and an installation part, run  
on the remote machine.

This has worked pretty well so far but, in the newest script of yt  
2.5.5, during the installation matplotlib-1.3.0 looks for additional  
dependencies of its own, and tries to download them from the Web,  
crashing the script. These dependencies are, according to  
matplotlib-1.3.0/lib/matplotlib.egg-info/requires.txt :

python-dateutil
tornado
pyparsing>=1.5.6,!=2.0.0
nose

I downloaded from the Web the first and third one, and installed them  
by hand before installing matplotlib. The second and fourth one are  
already among the yt dependencies, but I had to move in the right  
place, before installing matlotlib. In practice, I had to add the  
following lines before installing matplotlib:

do_setup_py $NOSE
do_setup_py pyparsing-1.5.6
do_setup_py $TORNADO
do_setup_py python-dateutil-1.5

and commenting do_setup_py $NOSE and do_setup_py $TORNADO in other  
parts of the script. In this way, the installation worked again.

In the yt website it is stressed to mention any issue with  
installation, therefore my email on this subject. Apparently my  
installation works well now, so you may consider to test and  
eventually incorporate these changes in install_script.sh , and  
whether to include pyparsing and python-dateutil to the yt  
dependencies. Alternatively, one could consider to go back to the  
previous version of matplotlib, which did not attempt such downloads,  
but I am not an expert in matplotlib, so possibly there were better  
reasons fo you to move to 1.3.0.

Cheers,

   Luigi
