爲什麼db：create停止工作？

直到最近db:create工作得很好，但現在它與我下面發佈的堆棧跟蹤失敗。這是一個String can't be coerced into Fixnum錯誤。爲什麼db：create停止工作？

這可能是什麼原因造成的？

我的密碼包含字母和數字，所以this不能成爲原因。

跟蹤只指向Rails代碼，而不是我自己的代碼，這使得調試挑戰。

我評論了我的模型中使用+運算符的方法，但是這並沒有解決任何問題。

我database.yml：

development: 
    adapter: postgresql 
    database: db/testivate_development 
    pool: 5 
    username: steven 
    password: <redacted> 
    host: localhost 

test: &test 
    adapter: postgresql 
    database: db/testivate_test<%= ENV['TEST_ENV_NUMBER'] %> 
    pool: 5 
    username: steven 
    password: <redacted> 
    host: localhost 

production: 
    adapter: postgresql 
    database: db/testivate_production 
    pool: 5 
    username: steven 
    password: 

cucumber: 
    <<: *test

跟蹤：

$ rake db:create

UPDATE

我得到同樣的錯誤，甚至當我把所有的移民來自/db/migrations/去的最簡單，最明確的database.yml可能的：

development: 
    adapter: postgresql 
    database: db/testivate_development 
    username: "steven" 
    password: "<redacted>" 
    host: localhost 

test: 
    adapter: postgresql 
    database: db/testivate_test 
    username: "steven" 
    password: "<redacted>" 
    host: localhost

您是否升級了運行此代碼的操作系統？這可能是由於Nokogiri標記的警告或可能需要重新編譯的另一個寶石的副作用。 –

謝謝格蘭特。我最近沒有升級操作系統，但我會重新編譯Nokogiri等。 –

Steven - 嘗試強制將密碼字符串用「」包圍起來，以便YAML解析器不會嘗試脅迫Fixnum。剛剛意識到你在另一個SO問題/答案中與此相關。無論如何，你有沒有試過？ –

看起來像bug是在enumstats寶石。你是否將它包含在你的Gemfile中？

你是對的。謝謝。我會將問題報告給Enumstats。 –
