運行rails服務器時出錯 - 如何更改rubygem環境的默認ruby？

所以，我遇到了這個問題（Syntax error when creating a Rails model），其中有與我相似的錯誤。我從中推斷出我的問題是使用Ruby 1.8而不是1.9。我嘗試卸載寶石，並按照其中一個答案中所述更新rubygems，但這並未解決問題。我也嘗試通過rvm設置默認的紅寶石爲1.9 - 它的工作原理，但它不能解決問題。運行rails服務器時出錯 - 如何更改rubygem環境的默認ruby？

當我運行「寶石ENV」我得到如下：

RubyGems Environment: 
    - RUBYGEMS VERSION: 1.8.23 
    - RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux] 
    - INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.8 
    - RUBY EXECUTABLE: /usr/bin/ruby1.8 
    - EXECUTABLE DIRECTORY: /usr/bin 
    - RUBYGEMS PLATFORMS: 
    - ruby 
    - x86_64-linux 
    - GEM PATHS: 
    - /usr/lib/ruby/gems/1.8 
    - /home/owner/.gem/ruby/1.8 
    - GEM CONFIGURATION: 
    - :update_sources => true 
    - :verbose => true 
    - :benchmark => false 
    - :backtrace => false 
    - :bulk_threshold => 1000 
    - REMOTE SOURCES: 
    - http://rubygems.org/

在USR/bin中我有一個「紅寶石」，這是一個符號鏈接到usr/bin中/ ruby1.9.1。

基本上，我需要知道如何改變紅寶石在這裏被使用（至少我認爲這將解決我的問題）。

我的操作系統是Linux Mint的12 Rails的--version返回「的Rails 3.2.3」

我的Gemfile是：

source 'https://rubygems.org' 

gem 'rails' 
gem 'bootstrap-sass' 
gem 'tilt' 
gem 'execjs' 
gem 'therubyracer', :platforms => :ruby 

group :development do 
    gem 'sqlite3', '1.3.5' 
    gem 'rspec-rails' 
    gem 'guard-rspec', '0.5.5' 
end 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '3.2.4' 
    gem 'coffee-rails', '3.2.2' 
    gem 'uglifier', '1.2.3' 
end 

gem 'jquery-rails', '2.0.0' 

group :test do 
    gem 'rspec-rails' 
    gem 'capybara', '1.1.2' 
    # System-dependent gems# Test gems on Windows 
    group :test do 
    gem 'rspec-rails' 
    gem 'capybara', '1.1.2' 
    gem 'rb-fchange', '0.0.5' 
    gem 'rb-notifu', '0.0.4' 
    end 
    gem 'guard-spork', '0.3.2' 
    gem 'spork', '0.9.0' 
end 

group :production do 
    gem 'pg', '0.12.2' 
end

PATH：

echo $PATH /usr/bin/rubycurrent:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

「的紅寶石」的回報：

/usr/bin/rubycurrent/ruby

你可以用RVM管理烏爾紅寶石版本 – 2012-04-27 02:29:52

@Kit何如前所述，我試圖通過RVM更改默認的版本，它的工作原理，但我仍然有同樣的問題。「rvm list default」返回「ruby-1.9.3-p194」。 – Bryan 2012-04-27 02:40:48

所以我終於弄明白。這就是我所做的。

首先，解決我卸載紅寶石1.8。從那以後，我試圖運行軌小號再次得到了以下錯誤：

bash: /usr/local/bin/rails: /usr/bin/ruby1.8: bad interpreter: No such file or directory

當我檢查在/ usr/local/bin目錄/軌腳本，我看到它包括在/ usr/bin中/ ruby1。頂部有8。嘗試噸不同的東西后得到它的工作，只有工作是卸載紅寶石，RubyGems的，導軌和RVM，並重新安裝所有這些事情（我不得不這樣做幾次......終於它的工作一次）。

您可以嘗試下面列出的內容，瞭解它是否適用於您： http://fatal-errors.com/ubuntu-10-ruby-1-9-rails-3-not-working-solved/99008。

編輯您的終端配置文件（在〜/ .bashrc，〜/ .zshrc等），並確保包含Ruby 1.9的目錄在通道中出現在/ usr/bin之前變量。一般來說，修改/ usr/bin是不好的，因爲這裏的東西通常是系統依賴關係。

感謝您的答案，但它似乎並沒有工作。這兩個文件是空的，並且將Ruby 1.9目錄添加到PATH的前面（通過終端）也沒有工作。 – Bryan 2012-04-27 02:37:01

這兩個文件不一定是你的shell配置。你在用什麼外殼？ – Max 2012-04-27 02:44:41

我正在使用bash。 – Bryan 2012-04-27 02:47:49
