`軌s`說： 「'需要'：無法加載這樣的文件 - PTY（LoadError）」 在Windows RailsInstaller

Question

我剛纔在我的Windows 10的電腦上安裝RailsInstaller。我不能夠運行rails s或rails g controller StaticPages home help。

我也試圖通過安裝宙斯寶石由this相關的StackOverflow問題的建議，但沒有成功解決這一問題。

的Gemfile：

source 'https://rubygems.org' 

gem 'rails',  '4.2.2' 
gem 'sass-rails', '5.0.2' 
gem 'uglifier',  '2.5.3' 
gem 'coffee-rails', '4.1.0' 
gem 'jquery-rails', '4.0.3' 
gem 'turbolinks', '2.3.0' 
gem 'jbuilder',  '2.2.3' 
gem 'sdoc',   '0.4.0', group: :doc 
gem 'pry-nav', group: [:development, :test] 

group :development, :test do 
    gem 'sqlite3',  '>= 1.3.9' 
    gem 'byebug',  '3.4.0' 
    gem 'web-console', '2.0.0.beta3' 
    gem 'spring',  '1.1.3' 
end 

group :test do 
    gem 'minitest-reporters', '1.0.5' 
    gem 'mini_backtrace',  '0.1.3' 
    gem 'guard-minitest',  '2.3.1' 
end 

group :production do 
    gem 'pg',    '0.17.1' 
    gem 'rails_12factor', '0.0.2' 
end 

錯誤：

回溯告訴我們，Web的控制檯寶石希望Ruby的PTY庫。不幸的是PTYs (pseudo-terminals)是在Unix/Linux的功能，它不存在於Windows，從而使Ruby庫確實沒有。

可以得到移動在幾個方面：

• 如果你不關心Web的控制檯的寶石，現在，只是從你的Gemfile中刪除它。

• 如果你真的需要Web的控制檯寶石，嘗試用這些寶石替換Web的控制檯：

  gem 'rubysl-pty', platforms: :ruby 
  gem 'web-console-rails3', platforms: :ruby

我按照以下步驟解決此問題：

1. 首先檢查你的Gemfile.lock的，如果你已經在那裏提到bcrypt版本，那麼你就不需要提的Gemfile的bcrypt版本。
2. 如果bcrypt版本中缺少Gemfile.lock的，然後在執行下列步驟： 一）創業板安裝bcrypt B）打開你的Gemfile和粘貼「寶石‘bcrypt’，‘〜> 3.1.7’」 Ç ）在控制檯運行命令：捆綁安裝

我希望通過以下給出的步驟可能會解決您的問題。
