having difficult in installing Seurat

[Shawn10312]

It is really strange, because in the before, I can install seurat easily in R3.5.

But after update the R to 3.6.1, I confront the problem in installing seurat in Centos as following:

install.packages('Seurat')
Installing package into ‘/gpfs/ycga/home/R/x86_64-pc-linux-gnu-library/3.6’
(as ‘lib’ is unspecified)
trying URL 'https://cran.rstudio.com/src/contrib/Seurat_3.1.1.tar.gz'

So how can I handle this problem?
