sudo apt-get install libcurl3-dev
This should fix it

@bakeris Thanks! Got this issue and fixed it for me as well.

Yikes!
Thank you soooooo much for this article. Whew! I was going insane.

So how on earth is anybody supposed to figure that out? when their patron gem install fails?

Could you explain how you knew this library was the culprit? So I might be able to live one more day in the event that I am unable to stumble upon the appropriate Google result?

Cheers again

@bakeris you safe me

This didn't fix my issue. But following lines did:

sudo apt remove -y libcurl4
sudo apt install -y libcurl4 curl libcurl4-openssl-dev

Fix that worked for me with Homebrew + macOS

brew reinstall openssl
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/opt/openssl/lib/
bundle

I wonder what should I install on Alpine Linux.

UPD: apk add ruby-dev curl-dev build-base

sudo apt-get install libcurl3-dev
This should fix it

Thanks 👍

for centos 7

$ yum install libcurl-devel

thanks for your response it worked for me!

@gabbio work for me, thank's
