python linux opensuse pyenv

I have tried installing python in pyenv env, in which i am getting the below error. I have added openssl to the path variable as openssl is already available, still it is throwing the same error.

Also, now tried with a separate user(not root). Same error! And tried to followup the wiki page, but for OpenSUSE i can't find much help on google too.

Can some one guide me on how to proceed this further.

    Please consult to the Wiki page to fix the problem.

There is an official guide for troubleshooting build problems here https://github.com/pyenv/pyenv/wiki/common-build-problems

So for openSuse you must first install the dependencies with:

zypper in zlib-devel bzip2 libbz2-devel libffi-devel libopenssl-devel \
readline-devel sqlite3 sqlite3-devel xz xz-devel

And also for Ubuntu/Debian:

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev python-openssl git
