rails版本bump后的rspec rails模板错误

我已经将我的Rails应用程序升级到6.0,现在我的测试出现了错误:

 Failure/Error: get :toggle, params: { id: allowed.id }

 ActionView::Template::Error:
   wrong number of arguments (given 2, expected 1)

我的档案里有:

group :test do
  gem 'rspec-rails'
end

如果我试着 gem 'rspec-rails', '~> 4.0' 正如安装指南在Github readme.md中所说,我得到了

Could not find gem 'rspec-rails (~> 4.0)' in any of the gem sources listed in your Gemfile.

gem 'rspec-rails' 使用:

gem 'rspec-rails', git: 'https://github.com/rspec/rspec-rails', branch: '4-0-maintenance'
gem 'rspec-core', git: 'https://github.com/rspec/rspec-core'
gem 'rspec-mocks', git: 'https://github.com/rspec/rspec-mocks'
gem 'rspec-support', git: 'https://github.com/rspec/rspec-support'
gem 'rspec-expectations', git: 'https://github.com/rspec/rspec-expectations'

然后我得到。。。

Bundler could not find compatible versions for gem "rspec-core":
  In Gemfile:
    rspec-core

    guard-rspec was resolved to 4.7.3, which depends on
      rspec (>= 2.99.0, < 4.0) was resolved to 3.9.0, which depends on
        rspec-core (~> 3.9.0)

    rspec-sidekiq was resolved to 3.0.3, which depends on
      rspec-core (>= 3.0.0, ~> 3.0)

Could not find gem 'rspec-core (~> 3.9.0)', which is required by gem 'rspec-sidekiq', in any of the relevant sources...

希望能得到帮助/指点。短暂性脑缺血发作
