windows下R报错解决方法

通过devtools安装github版R包报如下错

devtools::install_github("yutannihilation/gghighlight")

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): The namespace ‘processx’ 3.4.5 is loaded, but what is required is >= 3.5.0
解决方法

1. Install Rtools (https://cran.r-project.org/bin/windows/Rtools/ )
2. install.packages(c("processx", "callr"), type = "source")

> install.packages(c("processx", "callr"), type = "source")
Installing packages into ‘C:/Users/fxl/Documents/R/win-library/4.0’
