jekyll doctor error #158

Open alexandre1985 opened 4 years ago

$ jekyll --version
jekyll 3.8.6

When I run jekyll doctor, I do not know why I get this issue below:

$ jekyll doctor

I believe it is an bug. my _config.yml snippet is:

...
# i18N
languages: ['en']

# SASS
sass:
  sass_dir: assets/_sass-partials
  style: compressed

defaults:
  - scope:
      type: "pages"
    values:
      layout: "main"

permalink: pretty
...

Update: Also on my other jekyll project that has two i18n languages, I get:

This is still reproducible.

The line number of the culprit may have changed between versions (I have 1.7.0) because the stack trace above does not point to anything meaningful in my copy of the plugin, but it must be crashing trying to validate stuff because there is no lang key in the site.config hash.

This key doesn't need to be present in the config file, though; it is extracted from the languages key in the Site::process method.

I suspect the Site::process is not getting called (most likely by design) in the case of running jekyll doctor; I can confirm it by removing the languages key from the config file and running jekyll doctor - it crashes with the same stack trace instead of giving human-readable errors.

I do not know anything about Jekyll's internal structure, but there may be a method which the jekyll doctor command calls.

bundle exec jekyll --version
