I solved the error after researching for whole 1day: I rewrote the .tshrc file with brew() { local conda_env="$CONDA_DEFAULT_ENV" while [ "$CONDA_SHLVL" -gt 0 ]; do conda deactivate done command brew $@ local brew_status=$? [ -n "${conda_env:+x}" ] && conda activate "$conda_env" return "$brew_status" } I believe this sort of fixes should be known by support team, otherwise using a mac is bit complicated. I have seen lot of people facing these type of problems with the terminal.

I did few steps and deactivated conda by Step 1:conda deactivate Step 2:conda config --set auto_activate_base False But still error persists as on opening the terminal I'm getting (eval):65: command not found: dirname (eval):65: command not found: dirname Can anyone please help me out?
