Can't generate changelog with conventional-changelog

Question

I'm trying to set up a new workflow for a new project I'm working at. I really would like to use conventional-changelog, but for the moment is being impossible to me to make it work.

First of all, I can't even make the cli tool working. I did installed globally, but each time I'm trying to run: conventional-changelog --help on the shell, it said: conventional-changelog: command not found, but if I make npm ls -g -depth=0 I can see [email protected] package listed.

Another issue I'm having is that I can't create the changelog.

I have already some commits (indeed only one) on the angular format. It's like this:

feat(): onUrlChange event (popstate/hashchange/polling)

(this is an example copied from the docs, for debugging)

I also have a CHANGELOG.md empty file on the root and I have created a test.js with the following:

var conventionalChangelog = require('conventional-changelog');

conventionalChangelog({
  preset: 'angular'
})
  .pipe(process.stdout);

Whenever run node test I get :

conventionalChangelog().pipe(process.stdout);
                       ^
TypeError: Cannot read property 'pipe' of undefined
    at Object.<anonymous> (/Users/antonio/Projects/cabesa/test.js:45:24)
    at Module._compile (module.js:460:26)
    at Object.Module._extensions..js (module.js:478:10)

    at Function.Module._load (module.js:310:12)
    at Function.Module.runMain (module.js:501:10)
    at startup (node.js:129:16)
    at node.js:814:3

Any suggestion to put me on the right spot ?

My final goal will be to create some gulp tasks that manage all process automatically: deploying, documentation, testing, etc... but I'm stuck here.

Thanks

The problem is that their documentation only reflects the state of the code currently in the master branch. The last release was in April, when the exported function did not return anything (hence the undefined error you're seeing). You may try installing from the master branch (npm install https://github.com/ajoslin/conventional-changelog/tarball/master), or use the documentation that was available at the time of the last release (v0.0.17 as of this writing).
