在rails安装Ubuntu 12.04期间出错

问题描述

我在Ubuntu机器上安装rails，到目前为止，我没有遇到任何问题，请阅读以下教程：

然而，当我尝试安装rails时：

gem install rails

出现以下错误：

 构建原生扩展。这可能需要一段时间... 
错误：安装rails出错：

 Gem文件将保持安装在/ USR /本地/ RVM /宝石/红宝石1.9.3-P374 /宝石/json-1.7.6进行检查。 
结果记录到/usr/local/rvm/gems/ruby-1.9.3-p374/gems/json-1.7.6/ext/json/ext/generator/gem_make.out 
  

显然我已经检查过make是否可用，并且它在PATH上。实际上，使 和哪个rvm 给出以下结果的：
/ usr / bin / make
/ usr / local / rvm / bin / rvm

所以...我不认为它与PATH有关。

任何想法？我应该怎么做？

  rvm get head 
 rvm require run 
 rvm remove 1.9.3 
 rvm use 1.9.3 --install --default 
 gem install导轨
  

I'm installing rails on Ubuntu machine, so far I got no problems reading the following tutorials:

https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvmhttp://pragashblog.blogspot.com/2012/05/setting-up-rvm-ruby-and-rails-on-ubuntu.html

However when I try to install rails:

gem install rails

I'm getting the following error:

Building native extensions.  This could take a while...
ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.

Gem files will remain installed in /usr/local/rvm/gems/ruby-1.9.3-p374/gems/json-1.7.6 for inspection.
 Results logged to /usr/local/rvm/gems/ruby-1.9.3-p374/gems/json-1.7.6/ext/json/ext/generator/gem_make.out

Obviously I already checked that make is available, and that it is on the PATH. In fact, which make and which which rvm give the following results:/usr/bin/make/usr/local/rvm/bin/rvm

So... I don't think it's related to PATH.

Any Ideas?? What should I do?

解决方案

you are missing required packages:

rvm get head
rvm requirements run
rvm remove 1.9.3
rvm use 1.9.3 --install --default
gem install rails
