Having trouble getting past the core and netconf bundle installs. Assuming the error I get when installing the cisco-asr-ios-xr bundle is because the compliation of the core has failed (second error not shown or in the error log attached simply says it can't find ydk). Can you give me an idea of what is wrong? Getting an error when installing the core bundle creating /usr/local/etc/bash_completion.d     error: can't copy 'etc/bash_completion.d/pyang': doesn't exist or not a regular file --compile failed with error code 1 in /tmp/pip_build_root/pyang Exception information: Traceback (most recent call last):   File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 122, in main     status = self.run(options, args)   File "/usr/lib/python2.7/dist-packages/pip/commands/install.py", line 283, in run     requirement_set.install(install_options, global_options, root=options.root_path)   File "/usr/lib/python2.7/dist-packages/pip/req.py", line 1436, in install     requirement.install(install_options, global_options, *args, **kwargs)   File "/usr/lib/python2.7/dist-packages/pip/req.py", line 707, in install     cwd=self.source_dir, filter_stdout=self._filter_install, show_stdout=False)   File "/usr/lib/python2.7/dist-packages/pip/util.py", line 715, in call_subprocess     % (command_desc, proc.returncode, cwd)) InstallationError: Command /usr/bin/python -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/pyang/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-n3EUej-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/pyang ...
