ruby-on-rails - Spring和中间件冲突？

Question

我正在尝试使用 Google 添加 oauth2，关注 these instructions .

我在启动服务器时收到以下错误消息:

Exiting
You've tried to invoke Spring when it's already loaded (i.e. the Spring constant is defined).

This is probably because you generated binstubs with Spring 1.0, and you now have a Spring version > 1.0 on your system. To solve this, upgrade your bundle to the latest Spring version and then run `bundle exec spring binstub --all` to regenerate your binstubs. This is a one-time step necessary to upgrade from 1.0 to 1.1.

Here's the backtrace:

/Users/omonia/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/activesupport-5.0.0/lib/active_support/dependencies.rb:287:in `load'

安装的相关 gem :

gem 'google-api-client', '0.9'
gem 'omniauth'
gem 'omniauth-google_oauth2'

以下代码添加到 config/initializers/omniauth.rb:

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :google_oauth2, 'my Google client id', 'my Google client secret', {client_options: {ssl: {ca_file: Rails.root.join("cacert.pem").to_s}}}
end

这里发生了什么？遵循错误说明不会改变任何内容(Spring 是最新版本 1.7.2 并且运行 bundle exec spring binstub --all 仅返回“spring 已经存在”)。

把我的 comment作为答案，因为 OP 确认它确实帮助了他。请按照以下步骤安装新 Spring 并解决问题:

运行此 bin/spring binstub --remove --all

从 Gemfile 中删除 gem 并运行 bundle install .

现在添加 gem "spring", group: :development在 Gemfile 中，运行 bundle install和 bundle exec spring binstub --all关注 doc .现在一切都应该好了。
