[openstack-dev] [devstack] On using devstack

[Daniel Gitu]

Hello Steve,

I do apologize for contacting you directly. I have also sent this 
response to the official mailing list.


I was unable to find your email response to my question on the error 
while setting up keystone.


I found it by chance in the january list while looking for an unrelated 
solution.

I have tried using devstack it does a lot of the work for me, I did not 
understand a lot of what it did. I found this contrary to my objectives.


I am new to python and am looking to learn more and build my skill level 
and understanding. I am taking the modular approach by building 
different part of the openstack ecosystem as I learn different aspects.
I have started with keystone since it does the authentication of all 
services, so hopefully I can learn about authentication and its 
implementation.



Regards,

Daniel.

[openstack-dev] [keystone]Error while setting up a keystone development environment

[Daniel Gitu]

Hello,

I'm new to all this and I am in need of help to find out where I went wrong.
This is a bit lengthy, I have left a blank space between the text and 
the error

messages I received.
I first set up and activated a virtual environment then cloned the keystone
project into that environment.
I then proceeded to cd into keystone and executed pip install -r
requirements.txt and got the following errors:

Failed building wheel for cryptography
Failed cleaning build dir for cryptography
Failed building wheel for netifaces
Failed building wheel for pycrypto
Command "/home/grenouille/openstack/bin/python -u -c "import 
setuptools, 
tokenize;__file__='/tmp/pip-build-XqTJv_/cryptography/setup.py';f=getattr(tokenize, 
'open', open)(__file__);code=f.read().replace('\r\n', 
'\n');f.close();exec(compile(code, __file__, 'exec'))" install --record 
/tmp/pip-nFp6dT-record/install-record.txt 
--single-version-externally-managed --compile --install-headers 
/home/grenouille/openstack/include/site/python2.7/cryptography" failed 
with error code 1 in /tmp/pip-build-XqTJv_/cryptography/


The above errors were resolved by executing; sudo apt-get install
build-essential libssl-dev libffi-dev python-dev and re-running
pipinstall -r requirements.txt
I ran sudo apt install tox and executed tox in the keystone directory
As tox was installing dependencies the first line read:

ERROR: invocation failed (exit code 1), logfile: 
/home/grenouille/openstack/keystone/.tox/docs  /log/docs-1.log

ERROR: actionid: docs

The final error message read:

ERROR: could not install deps 
[-r/home/grenouille/openstack/keystone/test-requirements.txt, 
.[ldap,memcache,mongodb]]; v = 
InvocationError('/home/grenouille/openstack/keystone/.tox/docs/bin/pip 
install 
-chttps://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt 
-r/home/grenouille/openstack/keystone/test-requirements.txt 
.[ldap,memcache,mongodb] (see 
/home/grenouille/openstack/keystone/.tox/docs/log/docs-1.log)', 1)



Regards,
Daniel.
