Problems with Sphinx 1.5

[kraigher]

I started getting this error suddenly, the difference seems to be going from sphinx 1.4.9 to 1.5. Seems the blog path has not been created in the output path (docsbuild). The open call fails because it tries to open blog/atom.xml but the blog path does not exist. Maybe some implicit assumption in ablog is violated in 1.5.

No issues with Sphinx v1.5.1. What's the command that you run? Is this project available for me to try the same command?

[kraigher]

I will try 1.5.1 the failure was discovered with 1.5.

If you want to try check out this project: https://github.com/VUnit/vunit/commit/9eb5b0aa8fdadb4e67c402cf64c1edbab3b02461

Run "tox -e py35-docs"

[kraigher]

Also fails in the same way with 1.5.1

[abakan-zz]

Thanks, I was able to reproduce it in vunit docs, but I don't get the same in ablog docs. I will try to see what causes it in the next couple of weeks.

I just discovered that the _website/blog directory must exist. I created it by hand an the above error disappeared.

A new version of Ablog (v0.9.0) is out at this repo.

This issue should be fixed now but we made it explicitly support Sphinx>=1.6.
