My .bash_profile changes didnt take place even after restarting mac terminal, what can i do?

Question

So basically I tried to make changes to my path in my .bash_profile and save the changes but whenever I restart my terminal, it changes back to the default path and not the one ive set in .bash_profile

Ive tried to use the source ~/.bash_profile command but which i thought helped but somehow, when i restart the terminal, it doesnt change to the settings ive placed in .bash_profile

PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH

alias python=python3
alias pip=pip3

The expected output is when i type python in mac os terminal it should appear as python 3.7 and not python 2

Answer 1

Put your commands into ~/.zshrc file on macOS Catalina

nano ~/.zshrc 

Answer 2

Starting with macOS Catalina, the default interactive shell is zsh:

Make sure that you are using bash as your login shell.
You can check what is your login shell with the command echo $SHELL. If the result is /bin/bash, then you are using bash as your login shell. Otherwise you can change it with the command chsh -s /bin/bash.

Answer 3

I think what you are trying to do should be in .bashrc file, and not .bash_profile

also maybe your .bashrc file override those aliases
