OSX上的R:ggraph安装错误 [英] R on OSX: ggraph install error

问题描述

我正在尝试从CRAN安装ggraph软件包

I'm trying to install ggraph package from CRAN

> install.packages("ggraph")

这是输出

我已经运行brew install udunits，从源代码构建，尝试使用Github版本，等等，问题仍然存在.

I already run brew install udunits, build from source, try with Github version, etc and the problem persists.

如何绕过/解决此问题?

How do I bypass/solve this problem?

推荐答案

这是代码中的错误.我对该错误提交了修复程序.如果您从该拉取请求进行安装，它将可以正常工作:

This is a bug in the code. I submitted a fix for the bug. If you install from that pull request, it should work:

devtools::install_github("thomasp85/ggraph#78")
