我在网上发现此错误的所有信息都是针对Windows或Linux机器的。在我的一个谷歌搜索中，我看到某个地方可能是链接问题，验证开发工具的尝试失败了。有人可以帮忙解决这个问题吗？我也尝试过安装gem install sqlite3-ruby - --with-sqlite3-dir = / usr / local / lib，但这也无效。救命！谢谢！
答案 0 :(得分：1)
你需要安装sqlite3，gem需要链接的sqlite头文件。见this post.
您可以使用macports安装它：sudo port install sqlite3。
或者，如果您正在使用brew尝试brew install sqlite。
