Cannot connect to AnnotationHub server, using 'localHub=TRUE' instead Using 'localHub

001、问题

Cannot connect to AnnotationHub server, using 'localHub=TRUE' instead
Using 'localHub=TRUE'

library(AnnotationHub) 
library(biomaRt)
library(clusterProfiler)
hub <- AnnotationHub()       ## 该句报错

002、解决方法

library(AnnotationHub) 
library(biomaRt)
library(clusterProfiler)
proxy <- httr::use_proxy(Sys.getenv('http_proxy'))
httr::set_config(proxy)
AnnotationHub::setAnnotationHubOption("PROXY", proxy)   ## 添加以上三句
hub <- AnnotationHub()
