NPM attempts to publish twice - npm

Question

I am maintaining my first npm package so this might be an error on my part. Once build my package and commit it to git the next step is:
$ npm version patch
$ npm publish
The output (abridged) is as follows:
npm notice
npm notice 📦 #mememe/p3-model#0.7.2
npm notice === Tarball Contents ===
npm notice 188B README.md
npm notice 4.5kB dist/doc.d.ts
(etc)
npm notice 792B package.json
npm notice === Tarball Details ===
npm notice name: #mememe/p3-model
npm notice version: 0.7.2
npm notice filename: #mememe/p3-model-0.7.2.tgz
npm notice package size: 6.2 kB
npm notice unpacked size: 23.2 kB
npm notice shasum: cb5588ee626efc21532845c608fdb05a5fcd4db3
npm notice integrity: sha512-s7IK2HSXCNTUk[...]ZHxDgAOIr4Cnw==
npm notice total files: 11
npm notice
npm notice Publishing to https://registry.npmjs.org/
⸨⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⠂⸩ ⠇ : notice Publishing to https://registry.npmjs.org/
So far so good. But then somehow it attempts to publish again and gets an error that I am publishing on top of an old version. The output continues:
> #mememe/p3-model#0.7.2 publish
> npm publish

I only entered the npm publish command once. Is there some action of this command (perhaps an option in package.json) that would cause this?
The correct package gets published and I can use it in other projects. But this error is a bit disconcerting. Any suggestions?

Answer 1

I had the same issue and just solved it.
My problem was, that i had defined a script with publish in my package.json, so it was fired after/before again.
The idea behind that was to have a hint (like a command list) about the commands i use for building, testing, generating documentation and publishing. But unfortunately then the command was fired twice all the time.
In my case, the package.json looked like this:
{
"name": "my-package",
"version": "1.0.0",
"scripts": {
"build": "echo here could be a build job",
"test": "jasmine",
"publish": "npm publish"
}
Check your package.json for a entry at scripts which key is named publish. If you have an entry with the key publish, then remove this line entirely or use a different key for your script.
