Could you provide a link to your repo? Or at least your package.json and travis.yml ?

it runs yarn instead of npm install and I don’t know why ... I'm not familiar with yarn but can there be a reason that it doesn't install semantic-release from the dev dependencies?

Can you add npm ls semantic-release to before_script to see if it gets installed?

[pvdlg]

I think Travis use yarn if it finds a yarn.lock file but no package-lock.json.

But if I install with yarn install and run npm run semantic-release it works... Not how installing with yarn is causing the issue.

I think the answer may be here: yarnpkg/yarn#2739
Trying to set it into development mode on Travis..

[gr2m]

I looked for NODE_ENV=production but it doesn't look like your travis build set this environment variable

[st0ffern]

removing yarn.lock and generating package-lock.json seems to fix it..
Yet there is a new error:

WARN invalid config loglevel="notice"
[Travis Deploy Once]: There is only one job for this build.
npm WARN prepublish-on-install As of npm@5, `prepublish` scripts are deprecated.
npm WARN prepublish-on-install Use `prepare` for build steps and `prepublishOnly` for upload-only.
npm WARN prepublish-on-install See the deprecation note in `npm help scripts` for more information.

[pvdlg]

It's not an error, just warning from npm. You are using a prepublishscript [here](https://github.com/stoffern/universal-app/blob/master/package.json#L9) and that's a deprecated feature. You should replace it byprepareorprepublishOnly `.

See https://docs.npmjs.com/misc/scripts#prepublish-and-prepare

thanks 😉
Yet there seems to be a problem using yarn. I will close this for now but it may be reopened if more people get this error in the future..
