Hey! Can I work on this?

[JackMorganNZ]

Hi @pvskarthikeya, you are most welcome to do this. The links should probably be changed to:

• Latest version (rather than v2.0.0)
• And the old 1.?.? version

Feel free to ask any questions you have.

Hey! I am getting an error when i try to build the package.

Traceback (most recent call last):

    raise OSError("dlopen() failed to load a library: %s" % ' / '.join(names))
OSError: dlopen() failed to load a library: cairo / cairo-2

EDIT:
I tried to do the same thing in a python REPL: from weasyprint import HTML, CSS on line 406 is the one that is causing the issue

That's interesting, I haven't seen that before. Have you followed the installation instructions here: https://github.com/uccser/cs-field-guide/blob/develop/docs/installation.md I've realised the documentation for using PDF misses the point you will need to fully install Weasyprint, details on this here: http://weasyprint.readthedocs.io/en/latest/install.html

However this seems to be caused by creating PDF output, does it work correctly when you run the generation script normally without PDF? Don't worry about testing PDF output for this simple issue.

Hey! @JackMorganNZ I was able to build. I had to install all the dependencies locally with brew.
brew install cairo pango gdk-pixbuf libxml2 libxslt libffi and then I created a new virtualenv.
Then installed all the dependencies and after this I was able to build.

Edit: Build is complete and the log shows 4 Erros and 1583 Issues. Is this normal?
Added the log for your convenience.
log.txt

[JackMorganNZ]

Cool! That error log is fine, the error/warning numbers are quadrupled because I presume you are creating student website, student PDF, teacher website, and teacher PDF so our current system outputs errors for each one.

The one error is a known issue that is regarding Markdown headers but it's something we are allowing until we finishing building our CSFG generation system (it's intentionally breaking it), and all the warnings are from Weasyprint generation but are fine.

So that log is normal (but we hope in the future that normal is 0 errors and 0 warnings! 😄).

@JackMorganNZ I changed the text to 2.7.1. The links for the anchor tags seems to be the correct ones. What about the 2015 Student Version? Can i change it to 1.9.9. Since, that is what the link points to. Is that okay?

Snapshot of the new 404 page:

[JackMorganNZ]

I would recommend the changing text New 2016 Student Version](#) - Version 2.7.1 to Latest Student Version as then the number won't become out of date with each update.

[JackMorganNZ]

Also forgot to mention the second line '2015 Student Version - v1.9.9` is good as it mentions both the time of release and the version number.

[pvskarthikeya]

@JackMorganNZ I just added a PR for this. Please have a look.

[JackMorganNZ]

Perfect, thanks @pvskarthikeya.
