It happens when your git bash have modules like "npm", "yarn" locally NOT globally but your zsh terminal said module not found. This is how to fix it:

Ubuntu

1. Open .bashrc in Home

2. Open .zshrc in Home

3. Copy last 3 lines of the .bashrc and paste to the last line of .zshrc file. Mine is like:
   export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion


4. Save
