nodemon 2.0.17 not starting and showing require error

[Rishikant181]

Here is the error shown when I start nodemon

npm WARN exec The following package was not found and will be installed: nodemon@2.0.17 2:40:33 PM - Found 0 errors. Watching for file changes. /root/.npm/_npx/c08057651e53e122/node_modules/nodemon/bin/nodemon.js:15 require('update-notifier')({ pkg }).notify(); ^

Node.js v18.4.0

I am not using a local nodemon installation, but using npx to use it

Oops, seems that we opened two related on the same issue at the same time :)

Linking here #2031 in case the other details could be useful.

Same here

internal/modules/cjs/loader.js:1080
       throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
       ^

 Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /usr/local/lib/node_modules/nodemon/node_modules/update-notifier/index.js
 require() of ES modules is not supported.
     require() of /usr/local/lib/node_modules/nodemon/node_modules/update-notifier/index.js from /usr/local/lib/node_modules/nodemon/bin/nodemon.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
     Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /usr/local/lib/node_modules/nodemon/node_modules/update-notifier/package.json.

dupe of https://github.com/remy/nodemon/issues/2031 - will track there.

Downgrading to nodemon 2.0.14 resolved for me in the meantime

2.0.18 is available now - goes back to update-notifier@5.x
