gem install：错误：无法构建gem本机扩展 [英] gem install: ERROR: Failed to build gem native extension

问题描述

当我安装Ruby时，它说我应该添加：

  $（ruby -rubygems -eputs Gem.user_dir）/ bin 
  

到我的路径中，我将它添加到.bashrc中

当我尝试gem安装rails或任何其他gem它给出了错误：无法构建gem原生扩展。这是完整的错误：

 错误：执行gem时（Gem :: FilePermissionError）
你不用没有/usr/lib/ruby/gems/2.0.0目录的写入权限。 
 [alexander @ localhost〜] $ sudo gem install rails  - 无用户安装
构建原生扩展。这可能需要一段时间... 
错误：安装rails出错：
错误：无法构建gem本机扩展。 
 $ b $ / usr / bin / ruby​​ extconf.rb 
创建Makefile 
 $ b $ makeDESTDIR =
 sh：make：找不到命令
 
 
 Gem文件将保留安装在/usr/lib/ruby/gems/2.0.0/gems/atomic-1.1.10中进行检查。 
  

当我看到这个错误时，我发现人们通过安装ruby-dev包来解决这个错误。这在Arch Linux中不存在。任何其他选项，我可以尝试？

预先感谢！ 要构建本地扩展，您需要使用c ++编译器和工具。这很清楚地表明：

  sh：make：找不到命令
   make 实用程序外，您显然需要编译器本身（例如 gcc ）和公司。因此，
 
 
  sudo apt-get install gcc 
  
可以做到这一点。顺便说一句，正确建议的上述RVM方式肯定也需要构建工具。
 
I am using Arch Linux and installed Ruby (this is version 2.0.0).

When I installed Ruby it said I should add:
$(ruby -rubygems -e "puts Gem.user_dir")/bin
to my path, I added it to .bashrc

When I try to gem install rails or any other gem it gives the Error: Failed to build gem native extension. this is the full error:
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /usr/lib/ruby/gems/2.0.0 directory.
[alexander@localhost ~]$ sudo gem install rails --no-user-install
Building native extensions.  This could take a while...
ERROR:  Error installing rails:
ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb
creating Makefile

make "DESTDIR="
sh: make: command not found


Gem files will remain installed in /usr/lib/ruby/gems/2.0.0/gems/atomic-1.1.10 for inspection.
When I look this error up I see that people solve this error by installing ruby-dev packages, however this does not exist for Arch Linux. Any other option that I can try?

Thanks in advance!
解决方案
To build native extensions you need the c++-compiler and tools. This is said clearly:
sh: make: command not found
Except of make utility you obviously need the compiler itself (e. g. gcc) and company. Thus, 
sudo apt-get install gcc 
will do the trick. BTW, the properly suggested above RVM-way will definitely require build-tools as well.
