Неопределенный метод "accept" для nil: NilClass при запуске задач rake

0 голосов
/ 29 июня 2018

У меня есть приложение Ruby-on-Rails (3.2.2) с mysql2 (0.5.1) и MyQSL Server

mysql --version

mysql --version Вер. 8.0.11 для osx10.13 на x86_64 (Homebrew).

Когда я делаю bundle exec rake db:setup, создается БД.

При попытке bundle exec rake db:migrate происходит сбой: 

bundle exec rake db:migrate --trace                                                                           
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!

Tasks: TOP => db:migrate

Я не нашел никакого решения для этого. Мне пришлось установить gem "activerecord-mysql2-adapter", чтобы запустить его. Без этого драгоценного камня это бросает это: 

LoadError: Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (can't activate mysql2 (~> 0.3.10), already activated mysql2-0.5.1. Make sure all dependencies are added to Gemfile.)

Когда я запускаю свой старый (оригинальная версия mysql2 0.3.2.1), это происходит: (Я сделал обновление из-за этой ошибки) 

gem install mysql2 -v '0.3.21' --source 'https://rubygems.org/'                                                5 ↵  2.3.3    RSpec: 128.09%

Есть еще предложения?

Вам нужно установить mysql2 драгоценный камень или любую другую альтернативу. Gems с собственными расширениями иногда требуют development библиотек библиотеки, к которой они привязаны, для компиляции. Это сказало: 

# gem install mysql2 -v '0.3.21' --source 'https://rubygems.org/'
Building native extensions.  This could take a while...
  ERROR:  Error installing mysql2:
    ERROR: Failed to build gem native extension.

- означает, что вам нужно установить пакет libmysqlclient-dev (Ubuntu, на других ОС, пожалуйста, прочтите соответствующие документы.)

Чтобы установить этот пакет в Ubuntu, запустите sudo apt-get install libmysqlclient-dev.

TL; DR;

Это для Ruby on Rails 3.2.22

У меня на Mac была mysql версия 8.x. Я тоже установил 5.6. Я обнаружил, что исходный сервер MySQL для этого приложения был 5.7.

Итак, я установил mysql Version 5.7 и все заработало!

Очистка

Gemfile: 

gem 'mysql2', '~> 0.3.21' # in Gemfile


brew uninstall mysql mysql@5.6
brew install mysql@5.7

Очистите папки /Users/YOURNAME/.rbenv/versions/2.3.3/lib/ruby/gems от любых файлов mysql и activerecord-mysql2-adapter. 

gem uninstall activerecord-mysql2-adapter # each version
gem uninstall mysql2 # each version
bundle update mysql2
bundle install

Вот и все. Спасибо, ребята, за то, что направили меня

Попробуйте избавиться от gem activerecord-mysql2-adapter и просто установите gem mysql2, и он должен работать
