Issues building the site
Address already in use
When you try to build the site, you get this error in iTerm:
jekyll 2.5.3 | Error: Address already in use - bind(2)
This happens if a server is already in use. To fix this, edit your config file and change the port to a unique number.
If the previous server wasn’t shut down properly, you can kill the server process using these commands:
ps aux | grep jekyll
Find the PID (for example, it looks like “22298”).
Then type kill -9 22298 where “22298” is the PID.
Alternatively, type the following to stop all Jekyll servers:
kill -9 $(ps aux | grep '[j]ekyll' | awk '{print $2}')
shell file not executable
If you run into permissions errors trying to run a shell script file (such as mydoc_multibuild_web.sh), you may need to change the file permissions to make the sh file executable. Browse to the directory containing the shell script and run the following:
chmod +x build_writer.sh
shell file not runnable
If you’re using a PC, rename your shell files with a .bat extension.
“page 0” cross references in the PDF
If you see “page 0” cross-references in the PDF, the URL doesn’t exist. Check to make sure you actually included this page in the build.
If it’s not a page but rather a file, you need to add a noCrossRef class to the file so that your print stylesheet excludes the counter from it. Add class="noCrossRef" as an attribute to the link. In the css/printstyles.css file, there is a style that should remove the counter from anchor elements with this class.
The PDF is blank
Check the prince-list.txt file in the output to see if it contains links. If not, you have something wrong with the logic in the prince-list.txt file. Check the conditions.html file in your _includes to see if the audience specified in your configuration file aligns with the buildAudience in the conditions.html file
Sidebar not appearing
If you build your site but the sidebar doesn’t appear, check the following:
Look in your PDF config file and make sure you have a sidebar property, such as this:
pdf_sidebar: product2_sidebar
Make sure each TOC item has an output property that specifies web or pdf.
Understanding how the theme works can be helpful in troubleshooting. The _includes/sidebar.html file loops through the values in the _data/sidebar.yml file. There are if statements that check whether the conditions (as specified in the conditions.html file) are met. If the sidebar.yml item doesn’t have the right output, then it won’t get displayed in the sidebar. It would instead get skipped.
Sidebar isn’t collapsed
If the sidebar levels aren’t collapsed, usually your JavaScript is broken somewhere. Open the JavaScript Console and look to see where the problem is. If one script breaks, then other scripts will break too, so troubleshooting it is a little tricky.
Search isn’t working
If the search isn’t working, check the JSON validity in the search.json file in your output folder. Usually something is invalid. Identify the problematic line, fix the file, or put search: exclude in the frontmatter of the file to exclude it from search.
