使用 RVM 在 Ubuntu 上安装 Rails Path [英] Installing Rails Path on Ubuntu with RVM

问题描述

我是运行 Ubuntu 10.04 并尝试安装 Rails 的 Linux 菜鸟.我先安装ruby，然后安装RVM，然后下载安装rubygems，然后安装rails.

I'm a linux noob running Ubuntu 10.04 and trying to install rails. I first installed ruby and then RVM and then downloaded and installed rubygems and then installed rails.

Rails 似乎只有在命令前面有一个sudo"时才会响应.如果我在终端中编写rails new test"，我会得到这个:

Rails only seems to respond if I have a 'sudo' in front of the command. If I write 'rails new test' in the terminal I get this:

/usr/local/lib/site_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)
    from /usr/local/lib/site_ruby/1.8/rubygems.rb:214:in `activate'
    from /usr/local/lib/site_ruby/1.8/rubygems.rb:1082:in `gem'
    from /usr/bin/rails:18

如果我去终端并写rails -v"，我会得到同样的结果:

If I go to the terminal and write 'rails -v' I get the same thing:

   /usr/local/lib/site_ruby/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError)
        from /usr/local/lib/site_ruby/1.8/rubygems.rb:214:in `activate'
        from /usr/local/lib/site_ruby/1.8/rubygems.rb:1082:in `gem'
        from /usr/bin/rails:18

如果我去终端写sudo rails -v"，我会得到以下信息:Rails 3.0.0.rc

And if I go to the terminal and write 'sudo rails -v' I get the following: Rails 3.0.0.rc

'gem environment' 给了我这个:

'gem environment' gives me this:

RUBYGEMS VERSION: 1.3.7
  - RUBY VERSION: 1.9.2 (2010-07-11 patchlevel -1) [i686-linux]
  - INSTALLATION DIRECTORY: /home/josh/.rvm/gems/ruby-1.9.2-rc2@rails3tutorial
  - RUBY EXECUTABLE: /home/josh/.rvm/rubies/ruby-1.9.2-rc2/bin/ruby
  - EXECUTABLE DIRECTORY: /home/josh/.rvm/gems/ruby-1.9.2-rc2@rails3tutorial/bin

我怀疑我的路径设置不正确，但我不确定如何修复它.建议?

My suspicion is that my path is not set up correctly but I'm not sure how to fix it. Suggestions?

推荐答案

我在全新安装 Ubuntu 10.10 时也遇到了这个问题……即使在安装了$ rvm notes"记录的 rvm 和 ruby​​ 先决条件之后.

I also experienced this problem on a clean install of Ubuntu 10.10...even after installing the rvm and ruby pre-requisites documented by "$ rvm notes".

似乎是rvm"gem安装无法找到系统zlib安装的问题.上面丹尼尔的评论是一个很好的评论 - 遗憾的是它没有被列为答案.

It appears to be a problem with the "rvm" gem installation being unable to find the system zlib installation. Daniel's comment above is a great comment - a pity it is not listed as an answer.

所以我的解决方案是按照丹尼尔指出的说明进行操作:https://rvm.beginrescueend.com/包/zlib/.

So the solution for me was to follow the instructions pointed out by Daniel at: https://rvm.beginrescueend.com/packages/zlib/.

$ rvm pkg install zlib
$ rvm remove 1.9.2
$ rvm install 1.9.2

第一个命令在本地将 zlib 安装到您的 rvm 区域.第二个命令删除 ruby​​ 1.9.2，第三个命令使用 rvm-local zlib 重新安装 ruby​​ 1.9.2.

The first command install zlib locally into your rvm area. The second command removes ruby 1.9.2 and the third command reinstalls ruby 1.9.2 with the rvm-local zlib.

然后设置您的 ruby​​ 版本并安装 gems:

Thereafter set your ruby version and install gems:

$ rvm 使用 1.9.2
$ gem 安装随便"

$ rvm use 1.9.2
$ gem install "whatever"
