我是Ruby和Rails的新手，在空闲时间自学。我最近在我的gemfile文件中添加了一些宝石，现在我的脚手架给了我错误-在StackOverflow上找不到另一个解决我问题的答案（如果我的搜索能力不能达到要求，请提前道歉）。

如您所见，当它进入脚手架一代的“ _form.html”部分时，似乎出现了问题。
我检查以确保对文件没有奇怪的权限。我怀疑这与Foreman（这是Heroku的事情）有关，或者与dotenv（这是本地开发所需的东西，所以我可以存储秘密）有关。我在其他地方发现了一些关于Rails 5.1的早期Beta版本的帖子，它们与Thor有问题，但是我什至不知道Thor的作用（这是某种依赖性），他们说该错误已在后续发行版中修复（例如，我正在使用5.2）。
我的另一种理论是，它与Jbuilder和json内容有关，这也是我的新手，甚至都不知道从哪里开始解决。
有什么想法吗？同时，我将不用脚手架就可以工作。
无论如何，谢谢您的时间！
谢谢您的时间！
更新！
好吧，我自己解决了这个问题，只想报告。因此，我忘记了我也无法安装Nokogiri。每当我运行“捆绑更新”时，我都会收到一条错误消息，指出我需要确保正确安装了Nokogiri的最新版本，然后才能继续。我忽略了这一点，因为我无法弄清楚。只需按照nokogiri.org上的说明并安装必要的库即可解决此问题：
sudo apt-get install build-essential补丁ruby-dev zlib1g-dev liblzma-dev
gem安装nokogiri
完成此操作后，我对自己说：“嗯，这可能是解决脚手架问题的方法。确实是。
