EDIT: html2haml does work as advertised, however you must use version obtained from the current master branch of the haml github repoistory.
编辑：html2haml 确实像宣传的那样工作，但是您必须使用从haml github 存储库的当前主分支获得的版本。
The version of html2haml included with the haml gem currently available from rubygems is no good. This is the version you will get if you were to do gem install hamlright now. Using the version supplied with the gem will result in invalid haml, as it cannot process ruby properly.
当前可从 rubygems 获得的 haml gem 中包含的 html2haml 版本不好。如果您gem install haml现在这样做，这就是您将获得的版本。使用 gem 提供的版本将导致无效的 haml，因为它无法正确处理 ruby。

Way late to the game here, but this post still flies high in the Google when searching for similar solutions.
在这里玩游戏已经很晚了，但是在搜索类似的解决方案时，这篇文章仍然在谷歌中飞得很高。
Install the html2hamlgem, pop into your app/views directory and give this a try:
安装html2hamlgem，进入你的 app/views 目录并尝试一下：
find ./ -name '*.erb' -exec html2haml -e {} {}.haml \;
find ./ -name "*.erb.haml" -exec sh -c 'mv "" "${1%.erb.haml}.haml"' _ {} \;
find ./ -name '*.erb' -exec rm {} \;
The flaw in this solution is that it doesn't retain revision history from your old .erb files to your new .haml files. But at times where that revision history of those view files isn't a big deal, this solution has served me pretty well.
此解决方案的缺陷在于它不会保留从旧 .erb 文件到新 .haml 文件的修订历史记录。但是有时这些视图文件的修订历史不是什么大问题，这个解决方案对我很有帮助。
Also, be sure to watch for any errors in the html2haml line before you delete the old .erb files.
此外，在删除旧的 .erb 文件之前，请务必注意 html2haml 行中的任何错误。

html2haml is now in the html2haml gem, so you can use:
html2haml 现在位于 html2haml gem 中，因此您可以使用：
$ gem install html2haml
$ html2haml path/to/yourfile.html path/to/yourfile.haml
