我正在尝试在Mac上安装pagoda2 R软件包。
是否：
brew update
brew install cmake boost eigen gsl curl openssl wget
要求。
然后下载并安装了clang4-r.pkg软件包。
然后安装了Mac版gfortran。
然后在内部R部分中，在：
install_github("igraph/rigraph")
由于以下错误而失败：
* installing *source* package ‘igraph’ ...

If you meant to cross compile, use `--host'.
See `config.log' for more details
ERROR: configuration failed for package ‘igraph’
我尝试将.R / Makevars文件编辑为以下内容：
# The following statements are required to use the clang4 binary

但还是相同的错误消息。
有什么主意吗？
