记录一下今天在 Anaconda3 环境下 R==3.4.3 中安装 ggraph 的一些问题。

install.packages("ggraph") 发现 libudunits2.so was not found 错误：

libudunits2.so not found，是 udunits2 相关的库存在问题，CentOS 下可以使用 sudo yum install udunits2-devel 解决，在这里也可以使用 conda 同时解决 units 安装及 udunits2 的库错误。

$ conda install r-units
#没有报错，正常安装成功

从 rlang 开始，依次更新 rlang、ggplot2、ggforce 包。

最后，安装 ggraph，问题解决。

> install.packages("ggraph")

最后，简单总结一下：

ggraph_1.0.2 安装需要满足两个依赖：R (≥ 2.10), ggplot2 (≥ 2.0.0)。各种包相互依赖调用，根据 log 可定位哪一个包存在问题，然后逐一去解决。

object ‘enexprs’ is not exported by ‘namespace:rlang’，某个包(rlnag)无法加载特定对象(enexprs)可能有两个原因：

该包没有安装。

该包版本问题，导致目标对象(函数)发生增删处理。
