ENV: Kali VM 64 bit + apt-get install python3-pip

Hmmm looks like you'll also need openssl and various dependencies. Try:

sudo apt-get install python3-pip python-dev libssl-dev

Then try installing it.

[DigApis-Michael]

@jonluca Hi Jonluca, thank you for such a quick response. Yep, I've insalled the devs, and it's installed successfully. Great tool, recommended by a friend.

[jonluca]

Thanks!

I just tested it on my Kali box and I'm getting the same results. I'll work on this.

Thanks!

[DigApis-Michael]

@jonluca the exact command for Kali is:

apt-get install build-essential libssl-dev libffi-dev python3-dev

Just for your reference, if needed. :-)

[jonluca]

How odd. I ran sudo apt-get install build-essential libssl-dev libffi-dev python3-dev from here and it resolved my issue.

Make sure you do pip3 install ., as well.

Ah great to hear it worked for you!

[DigApis-Michael]

@jonluca Hah, I just want to make sure the dev is also for python3 (I got a feeling from you readme that I'd better use all python3 for this, so....).

I also found a solution asking to install python-dev, without 3. But anyway, that's ok for this tool. Feeling safe. 😂
