【问题描述】：
我做了几处更改，并尝试推送到 heroku，但它崩溃了，并给了我一个 debugger gem 错误，我在堆栈溢出中搜索了它。
我做了捆绑更新来修复它（正如人们所说），并从 gemfile 中删除了调试器。但是现在，它会给出另一个错误，并且不会推送或编译资产。
错误是：
NoMethodError: undefined method `environment' for nil:NilClass
这太奇怪了，因为它会重新安装 Heroku 中的所有 gem，并像第一次一样编译资产。请帮忙，我无法推送新功能！非常感谢

Post-install message from sitemap_generator:
NOTE: SitemapGenerator 4.x uses a new file naming scheme which is more standards-compliant.
If you're upgrading from 3.x, please see the release note in the README:
https://github.com/kjvarga/sitemap_generator#important-changes-in-version-4
The simple answer is that your index file is now called sitemap.xml.gz
and not sitemap_index.xml.gz, but please take a look and see what else has changed.
