gem install:错误:无法构建gem原生扩展

Question

我正在使用Arch Linux并安装了Ruby(这是2.0.0版本).

当我安装Ruby时,它说我应该添加:

$(ruby -rubygems -e "puts Gem.user_dir")/bin

在我的路上,我把它添加到.bashrc

当我尝试gem安装rails或任何其他gem时,它会给出错误:无法构建gem原生扩展.这是完整的错误:

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.

当我看到这个错误时,我看到人们通过安装ruby-dev软件包来解决这个错误,但是这对于Arch Linux来说并不存在.我还可以尝试其他任何选项吗？

提前致谢!

要构建本机扩展,您需要c ++ - 编译器和工具.这清楚地说:

sh: make: command not found

除了make实用程序,你显然需要编译器本身(例如gcc)和公司.从而,

sudo apt-get install gcc 

会做的.顺便说一句,上面正确建议的RVM方式肯定也需要构建工具.
