semantic-release fails to publish to npm

Question

I am using semantic-release npm module to do the releases in circle ci. I am getting following error

[semantic-release] [@semantic-release/npm] › ℹ Write version 1.0.0 to package.json in /home/circleci/tmp npm ERR! Version not changed, might want --allow-same-version

How do i fix this?

Answer 1

The error probably happen because you updated the version in package.json manually. You should let semantic-release doing that for you.

You should set the version in your package.json to 0.0.0-dev. If you want to have the updated package.json pushed to your repo use the @sematnic-release/git plugin.
