nbdev_build_lib produces the error messages stated below. When I tried commit Merge pull request #27 from muellerzr/master 99a3810 Jeremy Howard <j@fast.ai> 2021-01-10, 18:00 the error does not appear.

With commit 16a5ed81f8b29303322656cc191f74b6cf401fff a lot of files in docs directory were deleted. This seems to the reason for the error I got.

I got the same error on nbdev 1.1.11 with the nbdev template forked today

[hamelsmu]

Try again, we just made a new release

[lucharo]

Will try it tonight! Thanks @hamelsmu

Unfortunately it's still not working. As I mentioned in https://github.com/fastai/nbdev_template/issues/31#issuecomment-761765166 , a lot of files in ./docs have been removed. The error message I got states that at least the file ./docs/_data/topnav.yml is missing.

./docs have been removed. Yup. That is on purpose.

Can you point me to a repo where we can reproduce this error?

[hamelsmu]

@muellerzr are you having any trouble with new nbdev projects?

[muellerzr]

The issue here is you’re likely either not using the most recent nbdev version while trying to use the old nbdev_template or vice versa. You should either bring in the new template and use it with the latest nbdev or @hamelsmu can you drop a link to the conversion script/directions?

@urspb you are likely using the old template, can you try creating a brand new nbdev project, or using the script in the README to convert to the new template?

[muellerzr]

@urspb, Hamel and I worked on recreating your exact issue, so I'll try to explain what happened:

nbdev recently changed its template and how nbdev builds things. As a result we no longer have so much stuff in that docs/ folder. The exact issue here is you are using the latest nbdev_template but you aren't using the latest nbdev version (so your version is < 1.1.12). As a result you're experiencing this breaking change. So you should upgrade your version to 1.1.12 and it will run just fine.

[hamelsmu]

I'm going to go ahead and close this issue

[urspb]

@muellerzr your assumption is correct. I used nbdev version 1.1.11, which was the latest available on pypi.org at the time I first got the error. Thank you and @hamelsmu very much for your support and your efforts in this brilliant software.

[lucharo]

I can confirm that everything is working fine with the latest template and nbdev 1.1.12 thanks so much @hamelsmu !
