Unable to install pandas using Python3.8-CodePudding

When I try to install pandas on a Linux machine, I run into the below issue. Please let me know what dependency am I missing here or if there is any other issue.

The same command worked fine when I installed with Python3

Python version - Python3.8

# python3.8 -m pip install pandas

CodePudding user response：

Try:

python3.8 -m pip install --no-use-pep517 pandas

Maybe you should also upgrade pip and setuptools before:

python3.8 -m pip install -U pip setuptools

CodePudding user response：

Try maybe

pip cache purge to clean all cached packages,

also you can try to install after the update of pip - pip install --upgrade pip.

If that does not help, try to make a virtual environment with your python3.8 and try to install packages inside that venv.
