Ruby 'rails server' 问题

Question

每次我尝试运行“rails server”时都会出错

Abort trap: 6

我已尝试遵循其他提示，例如捆绑安装和更新，但仍然存在同样的问题。尝试 rvm install 1.9.3 并得到：

Try `brew tap --repair` and make sure `brew doctor` looks reasonable.

Brew 修复也没有用。

编辑：运行brew install gcc46 --env=std的结果

==> make bootstrap

你得手动安装这些依赖，试试

brew install automake

如果它给你这样的 automake 缺少链接的错误

您必须brew link autoconf 才能安装 automake 然后尝试这些命令

brew link --overwrite --dry-run autoconf

brew link --overwrite autoconf

brew install automake

它将安装 automake，然后您可以再次尝试安装 ruby​​。

如果不行，你可以试试别的方法：

溶胶2：

brew install gcc46 --env=std
brew install gcc; brew install gcc46 --cc=gcc-4.9
Manually build GCC 4.6 outside of Homebrew, using the same configure switches

你也可以试试这个：

$ brew install gcc
$ CC=/usr/local/bin/gcc-4.9 rvm install 1.9.1-p376 --enable-shared
