Question

当我尝试安装Rubocop时，我当前遇到此问题（我也无法安装nokigiri）：

~$ sudo gem install rubocop

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

    current directory: /var/lib/gems/2.5.0/gems/jaro_winkler-1.5.2/ext/jaro_winkler
/usr/bin/ruby2.5 -r ./siteconf20190320-24856-1cn9xqz.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/2.5.0/gems/jaro_winkler-1.5.2 for inspection.
Results logged to /var/lib/gems/2.5.0/extensions/x86_64-linux/2.5.0/jaro_winkler-1.5.2/gem_make.out

我尝试了其他解决方案，但是没有一个有效。有人知道为什么我会收到此错误吗？

Thx

您需要为ruby 2.5安装开发标头，但没有安装开发环境：

sudo apt-get install ruby2.5-dev

根据您的包装系统，也可能称为-devel。
