我正在尝试在 OSX Mavericks 上安装 sqlite3 gem，但我遇到了一个似乎很难解决的错误。通过谷歌搜索，我没有找到其他有同样问题的人。
基本上，当我运行 gem install 命令时，会发生以下情况:
Building native extensions. This could take a while...
ERROR: Error installing sqlite3:

我不知道 clang 是什么，但 gem 似乎在传递一个可能已被弃用的论点或其他什么？对这些东西有更多了解的人有任何想法吗？
最佳答案
Mavericks 中新版本的 XCode 显然附带了一个编译器，该编译器将未知传递的参数视为错误。
要解决此问题，请将环境变量设置为 ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future 以将错误降级为警告。
所以要安装 sqlite3 gem:
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future gem install sqlite3
