在Raspbian错误上安装Ruby Gem：无法构建Gem原生扩展 [英] Installing Ruby Gem on Raspbian Error: Failed to Build Gem Native Extension

问题描述

我试图安装一个ruby gem（ Jekyll ），并且我一直收到以下错误。

 错误：安装jekyll时出错：
错误：无法构建gem原生扩展。 
 
 /usr/bin/ruby1.9.1 extconf.rb 
 /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in`require'：can not load such file  -  mkmf（LoadError）
 from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in`require'
 from extconf.rb：1：in<<主>'
  

我正在使用Raspberry Pi。在询问Ruby的版本时，我得到以下内容：

  user @ raspberrypi〜$ ruby​​ -version 
 ruby​​ 1.9。 3p194（2012-04-20修订版35410）[arm-linux-eabihf] 
 -e：1：在< main>中：未定义的局部变量或方法'rsion'for main：Object（NameError）
  

几小时前，我运行以下命令安装了最新版本的Ruby：

  sudo curl -L https://get.rvm.io | bash -s stable --ruby 
  

为了找出问题的根源，我尝试安装不同的宝石（ lolcat ）。它安装成功，并完美地工作。

我做错了什么？

预先感谢您！

所以，我已经研究了StackOverflow上的其他问题解决方案

/ unable-to-install-gem-failed-to-build-gem-native-extension-can-load-such？rq = 1> here and 这里，我发现这是因为Ruby的版本我有。即使我安装了最新的RVM，我也必须运行以下命令来安装正确版本的Ruby：

$ b

  sudo apt-get安装ruby1.9.1-dev 
  

解决了我的问题。 ：）

I'm trying to install a ruby gem (Jekyll) and I keep getting the following error.

ERROR:  Error installing jekyll:
    ERROR: Failed to build gem native extension.

    /usr/bin/ruby1.9.1 extconf.rb
    /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from extconf.rb:1:in `<main>'

I'm using a Raspberry Pi. When asking Ruby it's version, I get the following:

user@raspberrypi ~ $ ruby -version 
ruby 1.9.3p194 (2012-04-20 revision 35410) [arm-linux-eabihf]
-e:1:in `<main>': undefined local variable or method `rsion' for main:Object (NameError)

A few hours ago, I installed the latest version of Ruby by running the command:

sudo curl -L https://get.rvm.io | bash -s stable --ruby

To find out the source of the problem I tried installing a different gem (lolcat). It installed successfully and works perfectly.

What am I doing wrong?

Thank you in advance!

解决方案

So, I've looked into other questions on StackOverflow here and here, and I found out it was because of the version of Ruby that I had. Even if I installed the latest RVM, I had to install the correct version of Ruby by running the command:

sudo apt-get install ruby1.9.1-dev

Solved my problem. :)
