#194 pip/easy_install taurus does not work

[Carlos Pascual]

UPDATE: This is no longer an issue in Taurus v>4 since the change to setuptools in [9f976f]. And as a workaround, the --egg parameter solves the problem for Taurus < 4 , as mentioned in the comments

Installing taurus with easy_install appears to work, but:

-resources are not built
-extra_packages are not installed

IMHO, doing "easy_install taurus" should yield similar results than downloading the tgz and doing "python setup.py install"

As a hint:
during easy_install, the following is printed:

cpascual@pc218:~/src/svn/taurus/dist$ PYTHONPATH=/tmp/kkinstdirtaurus311 easy_install --install-dir=/tmp/kkinstdirtaurus311 taurus-3.1.1.tar.gz
Processing taurus-3.1.1.tar.gz
Running taurus-3.1.1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-Tmbuxl/taurus-3.1.1/egg-dist-tmp-elgCV3

But surprisingly to me, the command "bdist_egg" cannot be called manually (?)

note: bdist_egg is part of setuptools and not of distutils

This worked for me on debian testing:
~~~~~~~~
cpascual@pc218:~/src/sardana/taurus(release-taurus-Jul14)$ mkdir /tmp/kkinstdirtaurus330
cpascual@pc218:~/src/sardana/taurus(release-taurus-Jul14)$ PYTHONPATH=$PYTHONPATH:/tmp/kkinstdirtaurus330 easy_install --install-dir=/tmp/kkinstdirtaurus330 dist/taurus-3.3.0.tar.gz
~~~~~~~~~
EDITED: I was wrong. It seemed to work but it did not install the extra_packages

Ticket moved from /p/sardana/tickets/20/

Can't be converted:

• _category: setup

I moved this ticket from the sardana list (it was #20 there).

A user (Yngve) gave a very useful hint in the mailing list: use the --egg option of pip (easy_install is not worth worrying about anymore):

pip install taurus --egg

So I think we can close this ticket and add this to the docs.

Thanks Yngve!

Hi all,

I wanted to install taurus for testing on my machine (CentOS 7). I
noticed in your install instructions that you recommend to download
the tarball from pip, so then I thought, 'why not just use pip
instead?'
That does not seem to work initially though:

$ pip install taurus

I am not sure where 'single-version-externally-managed' option comes from, probably someone more clever than me can explain. In any case, after a bit of searching online I found a recommendation to add the '--egg' option to pip. That worked very well:
$ pip install taurus --egg --user
Collecting taurus

Using cached taurus-3.6.0.tar.gz

Installing collected packages: taurus

Running setup.py install for taurus

Successfully installed taurus-3.6.0

(I added the --user as well to only install for my user account
without sudo)

Same is true for PyTango by the way. I would consider to maybe add
this as (an alternative) installation instruction in the
documentation.

Cheers,
Yngve
