Troubleshooting

zsh: command not found

Overview

• zsh: command not found after moving over to zsh following the Catalina upgrade
• Got the error above when running $ nvm --version command,

To Fix:

• Step 1 - the ~/.zshrc file need add some config:

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

• Step 2 - Run the command below:

$ source ~/.zshrc
