無法安裝大禮包的寶石 - 錯誤：無效的寶石：包損壞

Question

我試圖安裝施普雷寶石，但它給我這個錯誤：

gem install spree 
Fetching: httparty-0.13.3.gem (100%) 
When you HTTParty, you must party hard!

我試圖卸載並重新安裝Nokogir，與相同的結果。

當我試圖sudo gem install nokogiri另一個錯誤發生了：

ERROR: Error installing nokogiri:

Answer 1

看起來你已經安裝的Ruby系統。

您需要首先做到：

$ sudo apt-get install ruby-dev 

然後執行：

$ sudo gem install nokogiri 

我會鼓勵你使用Ruby版本管理器像RVM或rbenv管理的Ruby環境，而不是使用系統Ruby對你的開發環境。

Answer 2

請確保您安裝下面的命令：

sudo apt-get install libxslt-dev libxml2-dev 

現在嘗試安裝引入nokogiri。如果您使用RVM，請注意sudo。

sudo gem install nokogiri 

希望我的回答會有幫助。

謝謝。

Answer 3

我認爲RubyGems沒有正確下載文件。所以，系統報告該寶石已損壞。 刪除/home/tarek/.rvm/rubies/ruby-2.1.2/lib/ruby/gems/2.1.0/cache/nokogiri-1.6.4.1.gem，然後重新安裝gem。

$ sudo rm /home/tarek/.rvm/rubies/ruby-2.1.2/lib/ruby/gems/2.1.0/cache/nokogiri-1.6.4.1.gem 

$ gem install nokogiri
