Cannot read properties of undefined (reading 'filename') in Node v20.6.0 (yarn2)

It seems like nodemon doesn't work in Node 20.6.0 :

I have the following error : .yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/version.js:17 var promise = findPackage(path.dirname(module.parent.filename)) ^ TypeError: Cannot read properties of undefined (reading 'filename') at version (/Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/version.js:17:56) at pin (/Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/version.js:10:10) at /Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/index.js:81:5 at normaliseRules (/Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:125:3) at ready (/Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:108:9) at /Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:111:7 at callback (/Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:143:5) at /Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:196:5 at callback (/Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:143:5) at /Users/louisbrulenaudet/Desktop/Node.js - Site internet/.yarn/unplugged/nodemon-npm-3.0.1-07d6d759b1/node_modules/nodemon/lib/config/load.js:183:5

Node.js v20.6.0

Can you confirm how nodemon was invoked?

[louisbrulenaudet]

Dear Remy,

I hope this message finds you well. I sought to emulate the behavior demonstrated in Node version 20.5.1, which involved utilizing the "nodemon" command to execute the "app.js" script within the context of my "start" script ("start": "nodemon app.js") as delineated in the "package.json" file. Additionally, I endeavored to incorporate environmental variables from an ".env" file using the command "nodemon --env-file=.env app.js."

Thank you for your attention to this matter.

Sincerely, Louis

I can't replicate. It's going to need more information from you - specifically how to replicate:

~/dev/nodemon/issues/2142$ npm run start

> start
> nodemon app.js

[nodemon] 3.0.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,mjs,cjs,json
[nodemon] starting `node app.js`
^C%

~/dev/nodemon/issues/2142$ cat package.json app.js
       │ File: package.json
   1   │ {
   2   │   "scripts": { "start": "nodemon app.js" }
   3   │ }
       │ File: app.js
   1   │ require('http').createServer((req, res) => res.end('ok')).listen(8000);
   2   │

~/dev/nodemon/issues/2142$ node -v
v20.5.1
