ruby-on-rails - clang:错误:无法执行命令:段错误:11

Question

对不起我的英语。我在安装 json gem 时遇到了 clang 问题。我安装了 xcode、xcode 命令行工具等。我在 stackoverflow、google 中找不到问题，我也不知道。我有带有 xcode 6.1 的 Mavericks 10.9.4。我尝试了我在 stackoverflow、google 中找到的所有内容。日志:

Building native extensions.  This could take a while...
ERROR:  Error installing json:
ERROR: Failed to build gem native extension.

Answer 1

在 clang 下，我在编译一个 .c 文件时收到了类似的错误，该文件的一行长度超过 C99 标准允许的最大长度:4,095 个字符。错误消息在这里并不是很有用。
