LoadError: невозможно загрузить такой файл rails_helper (Rails 6 и Rspec)

Я пытаюсь написать тесты rspec для проекта rails 6.

Когда я запускаю rspec spec/controllers/user_spec.rb, я получаю эту ошибку

    Migrations are pending. To resolve this issue, 
      run:rails db:migrate RAILS_ENV=test 
    No examples found.

Я запускаю rails db:migrate RAILS_ENV=test и получаю эту ошибку

    Caused by:
    Bootsnap::LoadPathCache::FallbackScan:

    Tasks: TOP => db:migrate => db:load_config => environment
    (See full trace by running task with --trace)

Итак, я удаляю гем bootnap, перехожу в config / boot.rb и удаляю эту строку require 'bootsnap/setup'

Затем я запускаю установку пакета и снова пытаюсь запустить rails db:migrate RAILS_ENV=test.

Я получаю еще одну ошибку

На этом этапе я готов выбросить свой ноутбук в корзину. Я даже не знаю, что такое gem zeitwerk и что делает поточно-безопасный загрузчик кода. Я просто знаю, что это требуется для Rails 6.

Мое репозиторий на github находится здесь

Кто-нибудь знает, что я делаю не так?

Да, я видел этот пост. Я использую rspec 3.9, и я сделал rails generate rspec:install, так я получил файл rails_helper.rb. Но это все еще не помогло мне   -  person David Lee    schedule 21.11.2019

Я только что просмотрел ваше репо. На самом деле у вас нет rails_helper файла. Вы должны найти и заменить rails_helper, заменив его на test_helper

Так что у меня действительно есть файл rails_helper.rb. Он находится в spec / rails_helper.rb. Он создается автоматически при запуске rails generate rspec:install. Я считаю, что test_helper.rb нужен только для Minitest, который я не использую. - person David Lee; 21.11.2019

Ах, я понял это. Я не внимательно читал журналы ошибок.

Я использую драгоценный камень Devise. В моих журналах ошибок восьмая строка ниже упоминала файл в spec / factory / devise.rb.

Я посмотрел на этот файл и увидел, что я поместил require 'rails_helper.rb' в начало файла. Я удалил эту строку и теперь могу запустить rails db:migrate RAILS_ENV=TEST

Думаю, это урок по внимательному чтению журналов ошибок.
