Re: help with failed ydk core install / compilation

dave_stern · ‎01-10-2017

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

Hi David,

Thanks for raising this issue. Are you installing ydk core under virtualenv? I found a similar issue here, and the suggested approach is to "Running pip install --upgrade pip within virtualenv fixed this issue.". Would this help for this issue?

dave_stern · ‎01-19-2017

This didn't help fix the pyang compilation issue but I was able to clear some of the warnings during the compilation by executing the following after a warning with the new pip wheel I installed.

sudo -H pip install --no-index --find-links=/home/id22/Desktop/pywrapperetc/ /home/id22/Desktop/ydk-py-master/core/dist/ydk-0.5.2.tar.gz

Other sites offer that since we are using the virtual environment that I should not have to sudo.

I can now execute

pip install --no-index --find-links=/home/id22/Desktop/pywrapperetc/ /home/id22/Desktop/ydk-py-master/core/dist/ydk-0.5.2.tar.gz

some of the other pyang type messages point to bad pointers in the distribution, I just don't know.

Attached the latest log. Any assistance is appreciated, still have the same problem but solved another one with sudo -H

dave_stern · ‎01-24-2017

This ended up being the solution. I had to go into the pyang tar file (used the tar and not the wheel) and edit per the link that you sent. I was actually able to do this in Ubuntu which actually repacked it then it automagically then it all worked well. I did not try the wheel so it is possible that it was fixed in the wheel but not the tar. here

I have this issue trying to pip install on my macbook pro in a virtualenvwrapper. This is what I discovered:

There seems to be a problem with in pyang setup.py. I added the correct path to pyang in the pyang setup.py data_files and it worked.

Changed From:
data_files=[
('share/man/man1', man1),
('share/yang/modules/iana', modules_iana),
('share/yang/modules/ietf', modules_ietf),
('share/yang/xslt', xslt),
('share/yang/images', images),
('share/yang/schema', schema),
('etc/bash_completion.d', ['etc/bash_completion.d/pyang']),
]
)
To:
data_files=[
('share/man/man1', man1),
('share/yang/modules/iana', modules_iana),
('share/yang/modules/ietf', modules_ietf),
('share/yang/xslt', xslt),
('share/yang/images', images),
('share/yang/schema', schema),
#('etc/bash_completion.d', ['etc/bash_completion.d/pyang']),
('etc/bash_completion.d', ['bin/pyang']),
]
)

It'd great if you can share the details on OS and version you're using.

dave_stern · ‎01-19-2017

Ubuntu 14.04 LTS

xiaoqinz · ‎01-19-2017

Is there network limitation on this machine, so the local tarballs for ydk dependencies are used?

dave_stern · ‎01-19-2017

Correct. There is an Internet limitation. This machine does not and will not have access to the Internet. The machine does have access to an internal network but it does not host a local repo.

saalvare · ‎01-19-2017

The installation process takes care of many dependencies and relies on internet connectivity. I'm not familiar with the changes needed to make the installation work on a disconnected host. Let me suggest a couple of alternatives. We have a Vagrant sandbox that gives you an Ubuntu machine with YDK-Py pre-installed with hundreds of sample apps. The only requirement to run the sandbox is a host with Virtualbox and Vagrant installed. Alternatively, we can try sharing an OVA of that sandbox.

dave_stern · ‎01-19-2017

Ouch! I was hoping you would have an idea with the pip error log's.

We can move this app to virtualbox if we have too.

Dave

xiaoqinz · ‎01-19-2017

Hi Dave,

Would you mind provide some detailed information about those local files you have on that machine? I've purchased a laptop and just have ubuntu 14.04 installed, maybe I could try to reproduce this issue.

Thanks. I tried to reproduce and run into the same error when I tried to "pip install pyang-1.6.tar.gz" downloaded pypi.https://pypi.python.org/pypi/pyang/1.6 Other archive files for pyang 1.6 works fine for me(either pyang-1.6-py2.py3-none-any.whl from the same page or pyang 1.6 release from their GitHub release page).

I was able to install using the same command if I replace the "pyang-1.6.tar.gz" with "pyang-1.6-py2.py3-none-any.whl".
