安裝Charlock_Holmes-無法構建gem本機擴展

Question

我是Ubuntu的新手，可以通過終端安裝gem。 我在安裝charlock_holmes時遇到了一些麻煩。 當我嘗試安裝時，遇到了這個大錯誤，我無法做出以下正誤：

ryan@ubuntu:~/Desktop/linguist$ sudo gem install charlock_holmes -v '0.7.3'

我真的被困在下一步要做的事情上。 任何幫助將不勝感激。

從錯誤日志中，似乎未安裝g ++編譯器。 請使用以下命令進行安裝：

sudo apt-get install g++

然后運行以下命令：

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

注意 ： libicu-dev在機架上依賴於charlock_holmes

希望這會有所幫助！
