「Gem :: InstallError：devise需要Ruby版本> = 2.1.0」。運行的Ruby 2.3.1

Question

當在我的持續集成的機器我運行紅寶石2.3.1p112：

$ ruby --version 
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15] 

但是當我嘗試安裝寶石我得到的是沒有意義的錯誤：

$ bundle install --deployment 
Fetching gem metadata from https://rubygems.org/ 
Fetching version metadata from https://rubygems.org/ 
Fetching dependency metadata from https://rubygems.org/ 
Rubygems 2.0.14.1 is not threadsafe, so your gems will be installed one at a time. Upgrade to Rubygems 2.1.0 or higher to enable parallel gem installation. 
Using rake 10.5.0 
Using i18n 0.7.0 
Using json 1.8.3 
... 
Installing devise 4.0.1 

Gem::InstallError: devise requires Ruby version >= 2.1.0. 
An error occurred while installing devise (4.0.1), and Bundler cannot continue. 
Make sure that `gem install devise -v '4.0.1'` succeeds before bundling. 

安裝寶石全局工作：

$ sudo gem install devise -v '4.0.1' 
Successfully installed devise-4.0.1 
Parsing documentation for devise-4.0.1 
Done installing documentation for devise after 1 seconds 
1 gem installed 

，但它沒有什麼區別。關於RubyGems的投訴也奇怪，因爲我運行2.6.4：

$ update_rubygems 
RubyGems 2.6.4 installed 

任何想法可能什麼呢？

我的Gemfile看起來是這樣的：

    gem "poltergeist", "~> 1.9.0" 
end 

group :production, :staging do 
    gem "unicorn-rails", "~> 2.2.0" 
end 

我不使用RVM也沒有任何其他的Ruby /寶石經理。

重新安裝運行捆綁：

sudo gem install bundler 

固定的問題。
