[Tauruslib-users] install through pip

[Yngve I. L. <yng...@es...>]

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
> Collecting taurus
>   Using cached taurus-3.6.0.tar.gz
> Installing collected packages: taurus
>   Running setup.py install for taurus
>     Complete output from command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-zLtyIO/taurus/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-4hH39k-record/install-record.txt --single-version-externally-managed --compile:
>     usage: -c [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
>        or: -c --help [cmd1 cmd2 ...]
>        or: -c --help-commands
>        or: -c cmd --help
> 
>     error: option --single-version-externally-managed not recognized

>     ----------------------------------------
> Command "/usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip-build-zLtyIO/taurus/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-4hH39k-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-zLtyIO/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,
