ruby - 无法安装 restclient gem

Question

我想在 ruby​​ 中安装 restclient。我收到这些消息:

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

current directory: /var/lib/gems/2.3.0/gems/unf_ext-0.0.7.4/ext/unf_ext
/usr/bin/ruby2.3 -r ./siteconf20170427-2260-1nc7gtz.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include /ruby.h

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.3.0/gems/unf_ext-0.0.7.4 for inspection.
Results logged to /var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/unf_ext-0.0.7.4/gem_make.out

我的终端命令是:sudo gem install rest-client

谁能帮帮我？

你的系统缺少开发头文件，运行:

sudo apt-get install ruby-dev zlib1g-dev liblzma-dev
