在构建期间，我收到此错误
ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary

需要配置选项。
然后，我查找了每个mkmf.log文件，我可以在我的主目录中找到并找到这个文件：
~/.gem/extensions/x86_64-darwin-16/2.4.0/curb-0.9.3/mkmf.log
在查看此文件并搜索curlinfo_appconnect_time时，我看到了这一点：

对我来说似乎没问题。我对整个MacOS的东西比较新，所以需要帮助。我应该在哪里寻找解决这个问题的方法？
答案 0 :(得分：0)
只是为了记录，你可以尝试brew：
brew install gcc@4.9
