libnfs installation error

[Suchitra P]

Hi ,

I am very new to Python . I wanted to use libnfs module to access a nfs volume and perform operations.I directly downloaded libnfs tar and put it in /usr/lib64/python2.7/site-packages location since pip install was giving error .Now when I run the below code

//code

import libnfs 

nfs = libnfs.NFS('nfs://host-ip/nfsmnt') 

a = nfs.open('/foo-test', mode='w+') a.write("Test string") a.close() 

print nfs.open('/foo-test', mode='r').read()

//I get 

File "sample.py", line 1, in <module>

import libnfs File "/usr/lib64/python2.7/site-packages/libnfs/__init__.py", line 19, in <module> 

from .libnfs import * File "/usr/lib64/python2.7/site-packages/libnfs/libnfs.py", line 28, in <module> 

_libnfs = swig_import_helper() File "/usr/lib64/python2.7/site-packages/libnfs/libnfs.py", line 20, in swig_import_helper import _libnfs 

ImportError: No module named _libnfs.

I serioulsy dont know how to proceed.Please let me know how can I solve this issue.

Thanks ,

Suchitra

You can't just untar the package into site-packages. You have to build
both libnfs itself as well as the swig wrapper and then install it.

The process to do that is basically:
This module depends on and provides bindings for libnfs, a userspace NFS
library hosted at https://github.com/sahlberg/libnfs

Before you can build this module you must first install the latest version
of libnfs.

Building and installing
=======================
cd libnfs
make
cd ..
sudo python setup.py install
