因为最近需要用powerlaw包对一个无标度网络进行验证
但是在运行的时候出现了一个问题
当我用bootstrap这个功能时 会提示我
Error in checkForRemoteErrors(val) :
  one node produced an error: unable to find required package 'poweRlaw'

不知道是怎么一回事？求大神解答！
这是我的代码：
.libPaths("G:/Rproject/library")
library(igraph)
library(poweRlaw)
library(devtools)
library(parallel)
data<-read.csv2("t25.csv",sep=",")
data1<-data[,-1]
g1= graph.data.frame(data1, directed = TRUE)
plot(g1,layout=layout.auto,edge.arrow.width=3,margin=c(-0.5,0,-0.5,0),edge.arrow.size=0.5,vertex.label.dist=0.4,vertex.label.cex=0.6,vertex.size=3,vertex.label.degree=-pi/2,vertex.color=rainbow(7,alpha=0.3),edge.arrow.mode = "-")  
degree<-degree(g1,mode="all",normalized=F)
f1<-as.integer(degree)
e1<- displ$new(f1)
e1$getXmin()
e1$getPars()
estimate_pars(e1)
estimate_pars(e1, pars = seq(1.5, 2.5, 0.01))
(est_pl1<- estimate_xmin(e1))
e1$setXmin(est_pl1)
