Я работаю над проектом, который использует сервер Rails при использовании JSPM для организации файлов Javascript, а также использования Sprockets для конвейерных активов.Рельсы: не удается отобразить страницы, получить ошибку разбора JSON
Мой сервер rails работает, но в настоящее время я не могу отображать какие-либо представления. Я думаю, что это связано с тем, что звездочки не успешно управляют процессорами, которые компилируют JavaScript. (Дополнительная заметка: JavaScript - это ES6). Кажется, что следующая ошибка заключается в том, что сервер пытается отобразить страницу индекса, но JSON отсутствует, потому что JS не скомпилирован (моя догадка). Это говорит, я действительно не знаю, как решить эту проблему.
Ошибка ниже:
`JSON::ParserError in Application#index
Showing /Users/ben/agora/app/views/layouts/application.html.erb where line #14 raised:
A JSON text must at least contain two octets!
(in /Users/ben/agora/app/assets/javascripts/bundles/application.js.sfx)
