NPM attempts to publish twice

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/[email protected]
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 filename:      @mememe/p3-model-0.7.2.tgz

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/[email protected] 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.
