我添加了演示文件并在本地运行了该应用程序
但是当我部署到heroku时遇到了问题，内容没有显示
我阅读了nesta官方网站上的文档
http://nestacms.com/docs/deployment/heroku
但他们几乎只是发表评论而不是比提供指导
确保正确填写 config/config.yml（最重要的是确保关闭缓存，因为我们无法写入 Heroku 的文件系统）。
好吧，我在其他地方关注了他们的文档 http://nestacms.com/docs/config
然后对我的config.yml文件进行了更改。下面最相关的变化
title: "Practice Nesta Site"
subtitle: "Nesta is pretty cool"

name: Juan Gallardo
uri: nestademo1.herokuapp.com

# cache
# Set it to true if you'd like Nesta to cache your pages in ./public.
# Useful if you're deploying Nesta with a proxy server such as Nginx,
# but not in the least bit helpful if your pages are dynamic, or you're
# deploying Nesta to Heroku.
#
cache: false
# content
# The root directory where nesta will look for your article files.
# Should contain "pages" and "attachments" subdirectories that contain
# your actual content and the (optional) menu.txt file that links to your
# main category pages.
#
content: content
# Overriding "cache" and "content" in production is recommended if you're
# deploying Nesta to your own server (but see the deployment documentation
# on the Nesta site). Setting google_analytics_code in production is
# recommended regardless of how you're deploying (if you have a GA account!).
#
# Don't forget to uncomment the "production:" line too...
production:
cache: false
content: /var/apps/nesta/shared/content
# google_analytics_code: "UA-???????-?"
