当我在终端输入“heroku logs --tail”时如何修复以下错误？ 这是什么意思？

Question

I just started learning how to code a month ago by watching many videos and tutorials. This is the first time I'm using stackoverflow to ask questions. I appreciate your time in reading this! I'm in the process of deploying my app to Heroku but I'm not sure why it keeps showing up the following errors when I typed in "heroku open" in my terminal, it said I have "application error". I've already installed nodemon but it showed that "nodemon not found". I appreciate any help! (mac version: macOS Mojave)

sh: 1: nodemon: not found
npm ERR! file sh
: npm ERR! code ELIFECYCLE
: npm ERR! errno ENOENT
: npm ERR! syscall spawn
: npm ERR! finalproject-api@0.1.0 start: `nodemon server.js`
: npm ERR! spawn ENOENT
: npm ERR!
: npm ERR! Failed at the finalproject-api@0.1.0 start script.
: npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Answer 1

Can you change your Procfile to start your application with node instead of nodemon ? Nodemon is a utility that will monitor for any changes in your source and automatically restart your server. Perfect for development, but not ideal to use on Heroku since Heroku supports the node buildpack and not nodemon .

Something like the following:

Procfile:

web: node server.js

Hopefully that fixes your issue!
