How do I install Ruby with libyaml on Ubuntu 11.10?
提问by qian qian
I installed ruby-1.9.3-p0 on my Ubuntu 11.10 wubi and then rubygems to get Rails set up.
我在我的 Ubuntu 11.10 wubi 上安装了 ruby-1.9.3-p0，然后安装了 rubygems 来设置 Rails。
This is my code:
这是我的代码：
sudo ruby setup.rb
I got this error:
我收到此错误：
"/usr/local/lib/ruby/1.9.1/yaml.rb:56:in'<top(required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby."
I installed libyaml and reinstalled Ruby but still it doesn't work. The information changed and I have no idea what's wrong with it.
我安装了 libyaml 并重新安装了 Ruby，但仍然无法正常工作。信息改变了，我不知道有什么问题。

You must install the paquage libyaml-dev before installing ruby, if not you can still use extconf.rb for the missing library. So for this problem you can do (from the ruby install folder) :
您必须在安装 ruby 之前安装 paquage libyaml-dev，如果没有，您仍然可以使用 extconf.rb 来获取缺少的库。因此，对于此问题，您可以执行以下操作（从 ruby 安装文件夹中）：
cd ext/psych
ruby extconf.rb
make
make install
Extconf.rb is usefull for adding a library after have installed ruby.
Extconf.rb 可用于在安装 ruby 后添加库。

Ok, after a failed attempt at installing RoR on my Ubuntu 11.10 box, I combined the tips from this page and from this resource: http://www.thegeekwork.com/how-to-install-ruby-on-rails-in-ubuntu-11-10/
好的，在我的 Ubuntu 11.10 机器上尝试安装 RoR 失败后，我结合了此页面和此资源中的提示：http: //www.thegeekwork.com/how-to-install-ruby-on-rails-in -ubuntu-11-10/
This is the breakdown, step-by-step of what I just did to make this work (sorry if I didn't format this so great, I was just trying to keep it neat):
这是我为完成这项工作所做的逐步分解和分解（对不起，如果我没有把它格式化得这么好，我只是想让它保持整洁）：
1) Fresh install of Ubuntu 11.10
1) 全新安装 Ubuntu 11.10
2) me@Box:~$ sudo apt-get install curl
2) me@Box:~$ sudo apt-get install curl
3) me@Box:~$ sudo apt-get install git
3) me@Box:~$ sudo apt-get install git
4) me@Box:~$ sudo apt-get update
4) me@Box:~$ sudo apt-get update
5) me@Box:~$ sudo apt-get dist-update
5) me@Box:~$ sudo apt-get dist-update
6) me@Box:~$ sudo shutdown -r now
6) me@Box:~$ sudo shutdown -r now
7) me@Box:~$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
7) me@Box:~$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
8) me@Box:~$ gedit ~/.bashrc
8) me@Box:~$ gedit ~/.bashrc
9) add the following line to the end (and save the file)
9) 将以下行添加到最后（并保存文件）
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
10) me@Box:~$ source ~/.bashrc
10) me@Box:~$ source ~/.bashrc
11) me@Box:~$ type rvm | head -1
11) me@Box:~$ type rvm | head -1
After executing above command you should be getting this output - rvm is a function
执行上述命令后，你应该得到这个输出 - rvm 是一个函数
You've successfully installed the RVM. Next, you are supposed to install additional dependencies. To find out those programs type -
您已成功安装 RVM。接下来，您应该安装其他依赖项。要找出这些程序类型 -
12) me@Box:~$ rvm requirements
12) me@Box:~$ rvm requirements
After the above command, install the additional packages recommended by RVM -
执行上述命令后，安装RVM推荐的附加包——
13) me@Box:~$ sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion

14) me@Box:~$ rvm install 1.9.2
14) me@Box:~$ rvm install 1.9.2
(#14 takes a little while)
（#14需要一点时间）
15) me@Box:~$ rvm use 1.9.2
15) me@Box:~$ rvm use 1.9.2
(This selects the version you want to use)
（这将选择您要使用的版本）
(If you aren't sure about the ruby version currently being used, then type - ruby -v)
（如果您不确定当前使用的 ruby 版本，请输入 - ruby -v）
16) me@Box:~$ gem install rails
16) me@Box:~$ gem install rails
(this will take a little while...)
（这需要一点时间......）
17) Make a sample application as a test...
17) 制作一个示例应用程序作为测试...
me@Box:~$ rails new test_app
me@Box:~$ rails new test_app
me@Box:~$ cd test_app
me@Box:~$ cd test_app
me@Box:~/test_app$ rails server
me@Box:~/test_app$ rails server
AND THAT"S WHERE THIS THING DIDN"T WORK. ARRRRRRRRRrrrrrrrrrrrrrgh.
这就是这件事不起作用的地方。ARRRRRRRRRrrrrrrrrrrrrrgh。
So,
所以，
18) in your application folder ("test_app"), open Gemfile and uncomment "therubyracer" line
18) 在您的应用程序文件夹（“test_app”）中，打开 Gemfile 并取消注释“therubyracer”行
19) me@Box:~/test_app$ bundle install
19) me@Box:~/test_app$ bundle install
20) me@Box:~/test_app$ rails server
20) me@Box:~/test_app$ rails server
Done, and done.
完成了，完成了。
I don't understand why it set 0.0.0.0:3000 as the host address (I thought it would be 127.0.0.1), but quite frankly, that's not bothering me right now -- I got it to work (so far). Time to get going with some Rails! :D
我不明白为什么它将 0.0.0.0:3000 设置为主机地址（我认为它会是 127.0.0.1），但坦率地说，这并没有打扰我现在 - 我让它工作（到目前为止）。是时候开始使用一些 Rails 了！:D
I hope this helps anyone else who is looking to make this work! :)
我希望这可以帮助其他想要完成这项工作的人！:)
Note: I realize that #13 repeats some of the things I already installed, but I don't care, I'm just doing what the thing says. :/
注意：我意识到#13 重复了我已经安装的一些东西，但我不在乎，我只是按照上面说的去做。：/
Note2: Holy learning curve on just posting an answer! I wasn't sure what was considered "code" and apparently the prompt is considered code. Makes sense now :)
注2：仅发布答案的神圣学习曲线！我不确定什么被认为是“代码”，显然提示被认为是代码。现在有意义:)
Note3: This is my first "Answer" on StackOverflow! :D

If you are compiling ruby you might need libyaml-dev
如果您正在编译 ruby，您可能需要 libyaml-dev

Debian (and Ubuntu, etc.) packages that contain the files needed to install some other program from source usually end in -dev, e.g. libyaml-dev, so try installing that. Or just use rvm, it will actually install this for you.
包含从源代码安装其他程序所需的文件的 Debian（和 Ubuntu 等）软件包通常以-dev，例如结尾libyaml-dev，因此请尝试安装它。或者只是使用rvm，它实际上会为您安装它。

Compling yaml from its source will make it work. I am running the same config as yours. I followed this http://collectiveidea.com/blog/archives/2011/10/31/install-ruby-193-with-libyaml-on-centos/. It definitely works.
从源代码编译 yaml 将使其工作。我正在运行与您相同的配置。我跟着这个http://collectiveidea.com/blog/archives/2011/10/31/install-ruby-193-with-libyaml-on-centos/。它绝对有效。
