Fortify函数甚至不使用'if（！require（gpclib））install.packages（“gpclib”，type =“source”）gpclibPermit（）'

Question

我正在尝试强化.shp文件，但是我收到以下错误：

  

错误：isTRUE（gpclibPermitStatus（））不为TRUE

我尝试使用此代码修复它，正如其他问题所示：

library(broom)
library(maptools)
library(stringr)
library(ggplot2)
library(readr)
library(dplyr, warn.conflicts = F)
library(ggmap)
library(maps)
library(mapdata)
library(rgeos)
library(sp)
library(rgdal)
install.packages("gpclib", type="source")
require(gpclib)
if(!require(gpclib)) install.packages("gpclib", type = "source")
gpclibPermit()

shape1<-readShapeSpatial("/Users/marco/Documents/neweuropemap.shp")
shape1@data$id<-rownames(shape1@data)
shape.fort <- fortify(shape1, region = "id")

然而，错误再次发生。这是完整的代码：

但后来我收到以下错误（总结）：
