hisat2建立索引出错

hisat2建立索引出错，搞了很久解决不了，有朋友能告诉我怎么解决吗？

(base) cxl@DESKTOP-7OBAOAS:/mnt/e/GRCm39_ensemble$ hisat2-bulid -p 6 Mus_musculus.GRCm39.dna.toplevel.fa mus39

Command 'hisat2-bulid' not found, did you mean:
command 'hisat2-build' from deb hisat2 (2.2.1-3)
Try: sudo apt install
试着解决过
vim /.bashrc
PATH=/anaconda3/envs/hisat2:$PATH
source ~/.bashrc

怀疑过自己新建的环境变量没有生效,没看到hisat2(不知道自己想的对不对)
(base) cxl@DESKTOP-7OBAOAS:/mnt/e/GRCm39_ensemble$ conda info --envs

conda environments:

base * /home/cxl/anaconda3
rmats /home/cxl/anaconda3/envs/rmats
