sqlite3寶石彙編錯誤

Question

我想在OSX小牛上安裝sqlite3寶石，我遇到了一個似乎很難解決的錯誤。通過谷歌搜索，我沒有設法找到其他人有同樣的問題。

基本上，當我運行的創業板安裝命令，這是發生了什麼：

Building native extensions. This could take a while... 
ERROR: Error installing sqlite3:

我不知道什麼是鐺，但創業板似乎經過這也許是過時或什麼參數？任何有這方面知識的人都有什麼想法？

新版本的XCode在小牛顯然附帶了一個編譯器，將未知的傳遞參數視爲錯誤。

要解決此問題，請將環境變量設置爲ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future，以便將錯誤降級爲警告。

所以安裝sqlite3的寶石：

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install sqlite3
