unsupported format 'pybind'

[ashishk1994]

I am trying to bind using following command but getting unsupported format 'pybind' error.

sudo pyang --plugindir site-packages/pyangbind/plugin -f pybind turing-machine.yang -o bindings.py

Can someone please help me with this.

Hi,

Can you provide the output of:

/usr/bin/env python -c 'import pyangbind; import os; print "%s/plugin" % os.path.dirname(pyangbind.__file__)'

You should use whatever path is supply there (ideally the absolute path, rather than the relative one) after --plugindir.

This error (unsupported format) means that pyang is not finding the plugindir with pybind.py in it.

Cheers,
r.

Hi,
For below command,

/usr/bin/env python -c 'import pyangbind; import os; print "%s/plugin" % os.path.dirname(pyangbind.__file__)'

output is : /usr/local/lib/python2.7/dist-packages/pyangbind-0.2.1-py2.7.egg/pyangbind/plugin

I tried with above path as follows:

pyang --plugindir /usr/local/lib/python2.7/dist-packages/pyangbind-0.2.1-py2.7.egg/pyangbind/plugin -f pybind turing-machine.yang -o bindings.py

It is still giving me the same error.

unsupported format 'pybind' error.

Does your user have permission to read the /usr/local/lib/python2.7/dist-packages/pyangbind-0.2.1-py2.7.egg/pyangbind/plugin/pybind.py file? What version of pyang are you running, and on what distro (I assume Linux)?

[ashishk1994]

I tried it with the sudo but still the same error.
I am using pyang 1.6. pyang --version

pyang 1.6

and ubuntu 12.04
My plugin directory is :

/usr/local/lib/python2.7/dist-packages/pyangbind-0.2.1-py2.7.egg/pyangbind/plugin

Why did you put pybind.py at the last?

[robshakir]

pybind.py is the file that defines the format of pybind that your pyang is reporting it can't find.

How did you install pyangbind? I note that you have an egg specified in that path, but I only upload a wheel and sdist to PyPI. When I install it through pip on any Linux I have access to, it's never within an egg.

[ashishk1994]

Actually I was using pip version 1.2 . I upgraded the pip on my system then installed pyangbind again. It worked.
Thanks

Great - closing.
