February 14, 2018 admin

Sometimes we will get the following error while installation Python modules using pip.

Ignoring ensurepip failure: pip 8.1.1 requires SSL/TLS

This is because of the system don't have the SSL development dependencies.

We can resolve this problem by installing the following dependencies.

For Ubuntu,

apt-get install libssl-dev
apt-get install make build-essential libssl-dev zlib1g-dev libbz2-dev libsqlite3-dev

For Centos,

yum install openssl-devel
yum install zlib-devel bzip2-devel sqlite sqlite-devel openssl-devel
