如何安装ruby augeas gem？（马科斯·莫哈韦）

昨天我花了大部分时间寻找安装ruby augeas的明确答案。 我找不到好的解决办法

如何安装它

安装时出错：

我还安装了brew install

augeas pkg config

，但它显示了相同的错误

最后，我解决了这个问题

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

这就是你所需要的。configure脚本将运行pkg config以了解要添加到LDFLAGS和CPPFLAGS的内容

您是否安装了

libxml2

？例如，使用

brew安装libxml2

？是的，已在中安装libxml2。
