ERROR: ERROR: No matching distribution found for urllib==1.25

Cause / Solution

The cause was that I wanted to make a mistake in the package name.

--Error: ʻurllib == 1.25 --Correct: ʻurllib3 == 1.25

After specifying the correct package name, the package was successfully installed.

$ pipenv install urllib3==1.25
