Ruby on Rails的RVM使用

嗨，我是新來的Ruby on Rails的Ruby on Rails的RVM使用

我有我的Mac上安裝RVM

默認紅寶石1.8.7

$ ruby -v 
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin10.0] 
$ rails -v 
Rails 2.3.18 
$ gem -v 
2.2.2

當我嘗試使用Ruby 2.1.0我想加載失敗

$ rvm use 2.1.0 
Using /usr/local/rvm/gems/ruby-2.1.0 
$ ruby -v 
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin10.0] 
$ rails -v 
/usr/local/rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:298:in `to_specs': Could not find 'railties' (>= 0) among 14 total gem(s) (Gem::LoadError) 
    from /usr/local/rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/dependency.rb:309:in `to_spec' 
    from /usr/local/rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_gem.rb:53:in `gem' 
    from /usr/local/rvm/rubies/ruby-2.1.0/bin/rails:22:in `<main>' 
$ gem -v 
2.2.2

軌道，我不知道如何解決它

追加的'RVM info'輸出到你的問題。這告訴我們你的RVM/Ruby環境是如何配置的。 –

你有沒有用'bundle install'來更新你的新寶石版本的寶石集？ –

請參考：http://stackoverflow.com/questions/9212116/rails-could-not-find-railties –

看起來你已經安裝在global寶石軌道。你可以做的是：

從global gemset中刪除導軌。
然後在一個單獨的gemset中安裝Rails。但據我所知，Rails 2.3.18與Ruby 2.1.0不兼容。

下面是如何做到這一點或多或少準確的例子：

rvm use [email protected]   # switching to global gemset 
gem uninstall rails   # removing rails gem 
rvm use [email protected] --create # creating a separate gemset for rails 
gem install rails   # installing rails

爲了有效地使用RVM，您需要諮詢[gemsets文檔。 1

就是這樣！

更新。我相信你已經在sudo命令下安裝了RVM。爲了解決這個問題請按照下列步驟操作：

rvm implode        # remove RVM 
\curl -sSL https://get.rvm.io | bash # install it again 
rvm install 2.1.0      # install Ruby 2.1.0 
rvm use [email protected] --create --default # create default gemset for Rails 
gem install rails      # install Rails itself

爲了避免與權限的問題，我強烈建議你不要安裝寶石的過程中使用sudo。

gem unistall rails 錯誤：執行gem時（Gem :: CommandLineError）未知的命令unistall Unistall對我不起作用 – ntan

你有一個錯字。它是'卸載'，但不是'unistall'。 – marvelousNinja

對不起rvm使用[email protected] --create給我mkdir：/usr/local/rvm/gems/[email protected]rails：權限被拒絕 – ntan

重新啓動終端/主機
轉到您的項目位置
立即運行rvm use ruby-2.1.0 --default

，它會通過運行rvm list

然後，所有已安裝的RVM顯示當前RVM版本將與當前選定的符號一起顯示，並帶有*符號。

它適合你嗎？ –

我重新安裝紅寶石和導軌，並重新開始。 – ntan

運行以下命令：

sudo gem install rails 
bundle install 
rails s
