可能更新已有Bioconductor的版本

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install(version = "3.13")

R镜像源的切换

** byte-compile and prepare package for lazy loading
错误: package ‘ rappdirs ’ was installed before R 4.0.0: please re-install it
停止执行

错误记录

> library(scRNAseq)
> sce <- MacoskoRetinaData()

snapshotDate(): 2021-05-18
see ?scRNAseq and browseVignettes('scRNAseq') for documentation
loading from cache
错误: failed to load resource
  name: EH2690
  title: Macosko retina counts
  reason: 读取链结时发生了错误

原因： 大陆用户在直接连接默认CRAN时由于网络问题无法正常连接
修改源

source("http://bioconductor.org/biocLite.R")
options(BioC_mirror="http://mirrors.ustc.edu.cn/bioc/")
biocLite("RGalaxy")##这样就用中科大的镜像来下载包啦
## bioconductor还有很多其它镜像：https://www.bioconductor.org/about/mirrors/
##https://stat.ethz.ch/R-manual/R-devel/library/utils/html/chooseBioCmirror.html
options(BioC_mirror="https://mirrors.tuna.tsinghua.edu.cn/bioconductor")
options("repos" = c(CRAN="https://mirrors.tuna.tsinghua.edu.cn/CRAN/"))

发现问依旧
通过debug源码定位到cache目录~/.cache/R,
该目录下ExperimentHub里的数据没完成，有文件处于LOCK状态，删除该目录
再次运行代码会重新下载数据，等待下载结束
