pip install MySQL-python==1.2.5 not working [duplicate]

I'm trying to install MySQL-python with pip. I'm using Python v2.7.18 and pip v20.3.4

I'm trying it with:

pip install MySQL-python==1.2.5

But it gives this error:

Defaulting to user installation because normal site-packages is not writeable
