正在安装 Charlock_Holmes - 无法构建 gem 本机扩展

Question

我对 Ubuntu 和通过终端安装 gem 还很陌生。我在安装 charlock_holmes 时遇到了一些问题。当我尝试安装时，遇到了这个大错误，我无法确定：

ryan@ubuntu:~/Desktop/linguist$ sudo gem install charlock_holmes -v '0.7.3'
Building native extensions.  This could take a while...
ERROR:  Error installing charlock_holmes:

Gem files will remain installed in /var/lib/gems/1.9.1/gems/charlock_holmes-    0.7.3 for inspection.

我真的不知道下一步该做什么。任何帮助将不胜感激。

Answer 1

从错误日志来看，似乎没有安装g++编译器。请使用此命令安装：

sudo apt-get install g++

然后运行这些命令：

sudo apt-get install libicu-dev   
sudo gem install charlock_holmes -v '0.7.3'

注意：libicu-dev 是对 charlock_holmes

的机架前依赖

希望这会有所帮助！
