將Mongoid gem更新到版本5.0.0，將rails更新到4.0.0，它發出的問題是“ Bundler無法找到寶石“ railties”的兼容版本

Question

運行捆綁安裝時出現以下錯誤

Bundler could not find compatible versions for gem "railties":

在Gemfile中：devise（〜> 3.2.4）已解析為3.2.4，具體取決於發行版（<5，> = 3.2.6）

factory_girl_rails (~> 4.4.0) was resolved to 4.4.1, which depends on
  railties (>= 3.0.0)

jquery-payment-rails was resolved to 0.0.1, which depends on
  railties (~> 4.0.0)

jquery-rails (~> 3.0.0) was resolved to 3.0.4, which depends on
  railties (< 5.0, >= 3.0)

rails (~> 4.0.0) was resolved to 4.0.0, which depends on
  railties (= 4.0.0)

rspec-rails (~> 3.4.0) was resolved to 3.4.2, which depends on
  railties (< 4.3, >= 3.0)

sass-rails (~> 3.2.3) was resolved to 3.2.3, which depends on
  railties (~> 3.2.0.beta)

我也刪除了gemfile.lock文件，但仍然出現問題

好的，鑒於給您的錯誤，以下是對railties版本要求情況的一些分析：

1) railties (>= 3.0.0)
2) railties (~> 4.0.0) => (< 4.1, >= 4.0.0)
3) railties (< 5.0, >= 3.0)
4) railties (= 4.0.0)
5) railties (< 4.3, >= 3.0)
6) railties (~> 3.2.0.beta) => (< 3.2.1, >= 3.2.0.beta)

除了6）來自sass-rails gem以外，這里的所有版本依賴項都可以共存。 嘗試更新到最新版本的sass-rails ，您會沒事的（最新版本5.0.4 ），因為它使用了railties (>= 4.0.0, < 5.0) 。 另外，在4.0.0之后的所有sass-rails版本也都可以使用，因為那是在更改railties依賴關系時- 請參閱this 。

更新資料

我已經檢查了您的Gemfile ，為獲得所需的mongo版本，您可以進行的最小更改如下（對更改進行了評論）：

  gem 'database_cleaner',     '~> 1.5.1'
  gem 'faker',                '~> 1.5.0'

更改之后，您可能應該運行bundle update ，但是要小心，因為這會根據您的Gemfile更新所有gem。
