Hi @jeremy! I think it makes sense. I was simply following the assignment instruction. I was at Cygwin level, but I tried again on my AWS instance after reading your comment. I got the same error after trying pip install lxml. Is there a way to make the command line interface installation possible on an AWS instance? Or should I use a browser in Windows?
