执行此代码：Rscript $scripts/seurat_FindMarkers.r --rds $workdir/05.cell_type_ann/pbmc.added.celltype.rds \
-p FindMarkers.deg.B --group.by "stim" --ident.1 "stim" --ident.2 "ctrl" --subset.ident "B" \
--test.use DESeq2 --logfc.threshold 0.25
后报错：Error in DESeq2DETest(data.use = data.use, cells.1 = cells.1, cells.2 = cells.2, :
Please install DESeq2 - learn more at https://bioconductor.org/packages/release/bioc/html/DESeq2.html

想问下老师，问题出在哪里？应该怎么解决？
