Why I have to type zsh to source ~/.zshrc

[rickywu]

I installed zsh and ohmyzsh manually, because my env is offline, I copied all of them from a working env to offline env

Also I can see ohmyzsh after login and have to type zsh, I did chsh to zsh

After login, echo $SHELL shows /usr/bin/zsh but ohmyzsh not loaded, I have to type zsh again
