Resolution

This error message will be received when there is a proxy configured and no proxy parameters have been set in your environment. As pip uses HTTP and any application that uses HTTP to transfer and fetch data will have to export the proxy parameters.

Export the proxy environment variable to install packages using pip:

# export http_proxy="http://PROXY_SERVER:PORT"      (for HTTP)

or

# export https_proxy="https://PROXY_SERVER:PORT"      (for HTTPS)

If a proxy server uses authentication, set the proxy variables as follows:

# export http_proxy="http://USER:PASSWORD@PROXY_SERVER:PORT"      (for HTTP)

or

# export https_proxy="https://USER:PASSWORD@PROXY_SERVER:PORT"      (for HTTPS)

Now check if proxy has been set or not:

# env | grep proxy

Now, install the software using pip:

# scl enable rh-python35 bash

# pip install Beautifulsoup4
