我最近尝试将我的Jekyll网站推到Heroku。经过大量的反复试验，现在可以加载网站本身，但没有任何样式。我非常确定这不是relative_url的问题，因为我确保将{{ site.baseurl }}放在所有资产路径的前面。在运行jekyll serve时，一切都在本地正常运行。
这是我的config.ru文件：
require 'rack'
require 'rack/contrib/try_static'
# enable compression
use Rack::Deflater
# static configuration (file path matches reuest path)
use Rack::TryStatic,
:root => "_site", # static files root dir
:urls => %w[/], # match all requests
:try => ['.html', 'index.html', '/index.html'], # try these postfixes sequentially
:gzip => true, # enable compressed files
:header_rules => [
[:all, {'Cache-Control' => 'public, max-age=86400'}],
[['scss', 'css', 'js'], {'Cache-Control' => 'public, max-age=604800'}]
]
# otherwise 404 NotFound
notFoundPage = File.open('_site/index.html').read
run lambda { |_| [200, {'Content-Type' => 'text/html'}, [notFoundPage]]}
这是我的Rakefile：
task "assets:precompile" do
exec("jekyll build")
end
还有我的Procfile：
web: bundle exec puma -t 5:5 -p ${PORT:-3000} -e ${RACK_ENV:-development}
运行heroku日志--tail给出：
