Error while performing pip Install

I'm a Python beginner.
I would appreciate it if you could let me know how to deal with the error when I run pip installation from cmd.

environment
Windows 10 Python 3.7.3
pip19.0.3

Error (run pip install reportlab)

Collecting reportlab
Exception:

Similar Questions for Home SO and Similar Questions for Comments were all resolved by rewriting the registry.
From the registry editor, change the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable type to REG_DWORD.(It may be of the REG_BINARY type)

This is a guess, but installing Python 32-bit on Windows 64-bit seems to cause an error when pip goes to read the registry when it connects to the network.
Therefore, I expect that explicitly specifying proxy will work properly without invoking the decision logic using the registry.

In addition, it is stated that even if the Python 32-bit version was uninstalled and the 64-bit version was re-installed, the problem was not resolved.
The registry was then rewritten to resolve the issue.
