I wrote the below code

    metadata = config['metadata']
    if (sys.platform == 'win32'):
        requires = metadata.get('requires_dist', '').split('\n')
        metadata['requires_dist'] = '\n'.join(requires)
    config['metadata'] = metadata
    metadata['version'] = str(version)
    from pbr import packaging
    def my_get_script_args(*args, **kwargs):
        return _main_module()._orig_get_script_args(*args, **kwargs)
    packaging.override_get_script_args = my_get_script_args
    easy_install.get_script_args = my_get_script_args
    orig_get_version = packaging.get_version
    def my_get_version(package_name, pre_version=None):
        if (package_name == 'ryu'):
            return str(version)
        return orig_get_version(package_name, pre_version)
    packaging.get_version = my_get_version
