Solve error: legacy-install-failure In Pandas

Pandas is an open-source library in python which allows users to perform high-level data manipulation. It is one of the most important libraries in python in the sense of data structure programming and data analysis because it provides flexible, fast and expressive data structures. However, sometimes when you try to install this library using pip, you can get an ‘error: legacy-install-failure,’ which can prevent us from using this very important library. Let us see how we can solve this error in python.

To solve this problem, you need to install ‘pipwin’ because it may happen that the ‘pandas’ wheel might not support the python version you are working on; therefore, first, install ‘pipwin’.

pip install pipwin

And further, when you install ‘pipwin,’ install ‘pandas’ using ‘pipwin.’

pipwin install pandas

This should probably solve the ‘error: legacy-install-failure’ and allow you to install the pandas library and use it.
