During handling of the above exception, another exception occurred:

pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

Environment

Windows 10
Pyhon 3.8.7
pip 20.2.3

Cause

When response couldn’t gotten in time, both of exceptions are occurred. The time is defined by environment variable “PIP_DEFAULT_TIMEOUT”.

The cause is just a poor connection in my case.

Solution

Change the value of PIP_DEFAULT_TIMEOUT (the value is an integer in seconds).
Reference : “Environment Variables” from pip documentation

Method 1. Pass the option to pip directly

pip --default-timeout=1200 install pyside2

Method 2. Set the default value

set PIP_DEFAULT_TIMEOUT=1200
