gem 安装: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

我正在使用 Arch Linux 并安装了 Ruby(这是 2.0.0 版).

I am using Arch Linux and installed Ruby (this is version 2.0.0).

当我安装 Ruby 时，它说我应该添加:

When I installed Ruby it said I should add:

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

到我的路径，我将它添加到 .bashrc

to my path, I added it to .bashrc

当我尝试 gem install rails 或任何其他 gem 时，它给出错误:无法构建 gem 本机扩展.这是完整的错误:

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.

当我查看这个错误时，我看到人们通过安装 ruby​​-dev 包来解决这个错误，但是这在 Arch Linux 中不存在.我可以尝试其他任何选择吗?

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?

提前致谢！

推荐答案

要构建本机扩展，您需要 C++ 编译器和工具.这句话说的很清楚:

To build native extensions you need the c++-compiler and tools. This is said clearly:

sh: make: command not found

除了 make 实用程序，您显然需要编译器本身(例如 gcc)和公司.因此，

Except of make utility you obviously need the compiler itself (e. g. gcc) and company. Thus,

sudo apt-get install gcc 

会解决问题.顺便说一句，上面正确建议的 RVM 方式肯定也需要构建工具.

will do the trick. BTW, the properly suggested above RVM-way will definitely require build-tools as well.
