Error installing eth-brownie.

Answer 1

I ended up just using pip3 install eth-brownie

I was also having trouble with: pipx upgrade eth-brownie but pip3 install --upgrade eth-brownie==1.4.1 worked for brownie version 1.17.0 (which I needed because publish_source=True was broken in previous version)

I honestly don't understand how eth-brownie==1.4.1 installed 1.17.0 but it did... when I tried pip3 install --upgrade eth-brownie==1.17.0 it didn't work. smfh that's software for you...

You have to manually remove libpng and re-install it with pip install dlib --no-cache

if you don't have libpng installed just pip install dlib --no-cache

Worked well for me. solution here https://github.com/davisking/dlib/issues/1694
