我昨天大部分时间都在寻找安装 ruby​​-augeas 的明确答案。我找不到好的解决方案。

我该如何安装它？

安装时的错误：

gem install ruby-augeas
    Building native extensions. This could take a while...
    ERROR:  Error installing ruby-augeas:
        ERROR: Failed to build gem native extension.

        current directory: /Users/vmware/.rvm/gems/ruby-2.4.4/gems/ruby-augeas-0.5.0/ext/augeas

我也安装了 brew install augeas pkg-config，但它显示同样的错误。

最后，我已经解决了这个问题。

export PKG_CONFIG_PATH="/usr/local/opt/libxml2/lib/pkgconfig"

这就是你所需要的。配置脚本将运行 pkg-config 以找出要添加到 LDFLAGS 和 CPPFLAGS 的内容。
