Qiime tools import not working

Dear Admin

I am using again my Qiime2 after about 1 month. Earlier It was working fine.
Between (During this time, once I tried to install BowTie using this terminal)

Now whenI put "qiime tools import"
qiime tools import
--type EMPPairedEndSequences
--input-path emp-paired-end-sequences
--output-path emp-paired-end-sequences.qza

It says bash: qiime: command not found

See two top lines in the image, which I think were not here before.
