FAILED: /usr/local/lib/mailinabox/env/bin/pip install --upgrade pip

setup/functions.sh: line 19: /usr/local/lib/mailinabox/env/bin/pip: No such file or directory

i get this error when installing . i tried using

export DEB_PYTHON_INSTALL_LAYOUT='deb'

but still doesnt work.

UPDATE :
i ran

ln -s /usr/local/lib/mailinabox/env/local/bin/pip /usr/local/lib/mailinabox/env/bin/pip

which seems to fix it somehow but then i got

ERROR: Cannot uninstall ‘blinker’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

UPDATE ONCE AGAIN
i ran :

sudo /usr/local/lib/mailinabox/env/bin/pip install --upgrade rtyaml "email_validator>=1.0.0" "exclusiveprocess" flask dnspython python-dateutil expiringdict gunicorn qrcode[pil] pyotp "idna>=2.0.0" "cryptography==37.0.2" psutil postfix-mta-sts-resolver b2sdk boto3

which worked but , it seems i cant get past this

when i press enter , it seems like email validator is not installed even tho its specified in the command i ran above,.
