Ruby on Rails的RVM使用

嗨，我是新来的Ruby on Rails的Ruby on Rails的RVM使用

我有我的Mac上安装RVM

默认红宝石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

当我尝试使用Ruby 2.1.0我想加载失败

$ 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

轨道，我不知道如何解决它

追加的'RVM info'输出到你的问题。这告诉我们你的RVM/Ruby环境是如何配置的。 –

你有没有用'bundle install'来更新你的新宝石版本的宝石集？ –

请参考：http://stackoverflow.com/questions/9212116/rails-could-not-find-railties –

看起来你已经安装在global宝石轨道。你可以做的是：

从global gemset中删除导轨。
然后在一个单独的gemset中安装Rails。但据我所知，Rails 2.3.18与Ruby 2.1.0不兼容。

下面是如何做到这一点或多或少准确的例子：

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

为了有效地使用RVM，您需要咨询[gemsets文档。 1

就是这样！

更新。我相信你已经在sudo命令下安装了RVM。为了解决这个问题请按照下列步骤操作：

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

为了避免与权限的问题，我强烈建议你不要安装宝石的过程中使用sudo。

gem unistall rails 错误：执行gem时（Gem :: CommandLineError）未知的命令unistall Unistall对我不起作用 – ntan

你有一个错字。它是'卸载'，但不是'unistall'。 – marvelousNinja

对不起rvm使用[email protected] --create给我mkdir：/usr/local/rvm/gems/[email protected]rails：权限被拒绝 – ntan

重新启动终端/主机
转到您的项目位置
立即运行rvm use ruby-2.1.0 --default

，它会通过运行rvm list

然后，所有已安装的RVM显示当前RVM版本将与当前选定的符号一起显示，并带有*符号。

它适合你吗？ –

我重新安装红宝石和导轨，并重新开始。 – ntan

运行以下命令：

sudo gem install rails 
bundle install 
rails s
