Hi @bjrbhre, as per the script

autoload -U add-zsh-hook
load-nvmrc() {
  local node_version="$(nvm version)" # gets default node version
  local nvmrc_path="$(nvm_find_nvmrc)" # gets path of .nvmrc in current dir

  if [ -n "$nvmrc_path" ]; then
    # following variable is assigned the node version listed in the .nvmrc, if installed
    # else it is assigned "N/A"
    local nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")") 
    if [ "$nvmrc_node_version" = "N/A" ]; then
      nvm install # when "N/A" it installs this new node version
    elif [ "$nvmrc_node_version" = "$node_version" ]; then
      nvm use # if already installed it will use this node version
    fi
  elif [ "$node_version" != "$(nvm version default)" ]; then
    echo "Reverting to nvm default version"
    nvm use default
  fi
}
add-zsh-hook chpwd load-nvmrc
load-nvmrc

i think without removing the ! in the second check, it would never execute an nvm use, hence the change

Hi @sidsakhadeo. Thanks for your comment and sorry for the delay in answering.

If [ "$nvmrc_node_version" = "$node_version" ] then you just don't need to execute nvm use because it means that you already use the version listed in nvmrc. You need to execute nvm use if they don't match. I do believe the ! is useful.
