ruby-on-rails - 在 centos 上安装 charlock_holmes 时出错

Question

我正在尝试在 centos 上安装 charlock_holmes gem，但我一直在获取

Installing charlock_holmes 0.7.6 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

***** icu required (brew install icu4c or apt-get install libicu-dev)
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You 
may need configuration options.

To see why this extension failed to compile, please check the mkmf.log which 
can be found here:

/usr/local/rvm/gems/ruby-2.2.5/extensions/x86_64- 
 linux/2.2.0/charlock_holmes-0.7.6/mkmf.log

extconf failed, exit code 1

An error occurred while installing charlock_holmes (0.7.6), and Bundler
cannot continue.

In Gemfile:
copyright-header was resolved to 1.0.22, which depends on
github-linguist was resolved to 6.2.0, which depends on
  charlock_holmes

我也尝试安装 libicu-dev，这就是我没有可用的软件包 libicu-dev。错误：无事请帮忙，谢谢。
