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

  • Try sourceing your bashrc profile. Discussed here: https://stackoverflow.com/questions/21211281/source-command-on-mac – Brandon Nov 02 '19 at 17:50

    Are you sure you are using `bash`? If this is a new account on macOS 10.15, you are probably using `zsh` instead. – chepner Nov 02 '19 at 18:01

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

nano ~/.zshrc

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.

    Got this after the Big Sur update 11.0.1, the default interactive shell is forced to zsh. Thats why my bash_profile changes weren't working, they kept resetting after restarting terminal. After issuing your fix, it finally worked. Thanks so much – IT-Girl Dec 02 '20 at 09:54

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

you can read more about the difference of them here

    On macOS, a terminal window opens a login shell, not an ordinary interactive shell, since the terminal emulator itself isn't being started in an environment set up by a login shell. – chepner Nov 02 '19 at 18:14

The solution that fixed this problem for me was changing the shell terminal preferences to open shell with command(complete path)

But thank you all for the replies greatly appreciated
