Issue with dir2pi while a package name has uppercase letters in it

[debraj-manna]

I have a directory full of packages like below

dmanna@ubuntu:~/pyt/pkg$ ls
cdiff-1.0.tar.gz
certifi-2018.4.16-py2.py3-none-any.whl
chardet-3.0.4-py2.py3-none-any.whl
click-6.7-py2.py3-none-any.whl
idna-2.7-py2.py3-none-any.whl
kazoo-2.5.0-py2.py3-none-any.whl
patroni-1.4.4.tar.gz
prettytable-0.7.2.tar.bz2
psutil-5.4.6.tar.gz
psycopg2-2.7.4.tar.gz
python_dateutil-2.7.3-py2.py3-none-any.whl
pytz-2018.4-py2.py3-none-any.whl
PyYAML-3.12.tar.gz
requests-2.19.1-py2.py3-none-any.whl
six-1.11.0-py2.py3-none-any.whl
tzlocal-1.5.1.tar.gz
urllib3-1.23-py2.py3-none-any.whl

After running dir2pi pyt/pkg the content of simple

dmanna@ubuntu:~/pyt/pkg/simple$ ls
cdiff    click       kazoo        psutil           pytz      six
certifi  idna        patroni      psycopg2         pyyaml    tzlocal
chardet  index.html  prettytable  python-dateutil  requests  urllib3

Now on trying to install patroni it is throwing the below error

dmanna@ubuntu:~$ sudo pip install --index-url=file:///home/dmanna/pyt/pkg/simple patroni
