Node.js v17.5.0
[nodemon] app crashed - waiting for file changes before starting...

Answer 1

The latest release of Node.JS is what is causing this issue. In your package.json, make sure to set your engine to"engines": { "node": ">=0.12 < 17.5.0" } and you should be fine.
Solution which worked well for me:)
Step 01: Open your terminal and copy paste below command.
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | zsh
Wait patiently until its done.
Step 02: sudo vim ./zshrc
Step 03: Press I for Insert Mode and copy paste below command. Must be same in three lines.
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
[ -s "$NVM_DIR/bash_completion" ] && . "$NVM_DIR/bash_completion"
then press ESC key :wq (write and quite).
Step 04: brew install nvm
step 05: nvm install node (which will download latest version node)
step 06: nvm ls-remote (which make all the version available)
step 07: nvm install 14 (An Example)
step 08: nvm use 14 (this make it as default version)
