想要LoadData("ifnb")需要library(SeuratData)，但是devtools::install_github('satijalab/seurat-data')会报ERROR: lazy loading failed for package 'SeuratData'

甚至library还出了错（之前一直正常library）：

library(Seurat)
Error: package or namespace load failed for ‘Seurat’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
载入了名字空间‘spatstat.utils’ 2.3-1，但需要的是>= 3.0.0

尝试安装|包源：|spatstat.utils_3.0-1.tar.gz |

安装了Rtools，配置了环境变量，然后再安装spatstat.utils_3.0-1.tar.gz。一定是.gz，.zip不行。spatstat.utils_3.0-1成功安装。

然后再devtools::install_github('satijalab/seurat-data')就行了

之前一直可以library(Seurat)的，突然不行了，花一上午时间搞这个

packageurl = 'https://cran.r-project.org/src/contrib/vctrs_0.5.0.tar.gz'
install.packages(packageurl, repos = NULL, type = 'source')
