Thanks for the heads up. Will take a look when I have a minute.

Apparently py2-lxml is not available in alpine:edge, so you should use 3.10

https://pkgs.alpinelinux.org/packages?name=py2-lxml&branch=v3.10

Hello. The same problem with py2-lxml and py2-requests

Same problem again: alpine:latest is now pointing to 3.11, which does not contain py2-lxml
So for now alpine:3.10 is the only version compatible with BlackWidow...

Just pushed the fix for this in the latest version. To apply the fix, please re-clone the repository and re-run the install.sh file.

git clone https://github.com/1N3/BlackWidow
cd BlackWidow
sudo bash install.sh
