Heroku deploy failed: [remote rejected] master -> master (pre-receive hook declined): error: failed to push some refs

I copied an existing app into a new repository. It works locally. Deploys work for the original. I'm using PHP, Yii, and Composer. I don't know what

This is in my
if it's important

"require": {
"fxp/composer-asset-plugin": "^1.0",

Answer Source

I had to run

composer global require fxp/composer-asset-plugin --no-plugins

then composer update, then commit, then push. It got past that part.

remote:          - Installing fxp/composer-asset-plugin (v1.1.3)
remote:            Downloading: 100%

It broke again and I had to delete vendor/ and composer.lock. You can remove the global plugin with composer global remove "fxp/composer-asset-plugin". Someone also said you can use rm -r ~/.composer. It was giving a different error in the interim. For some reason, even if you have "fxp/composer-asset-plugin": "*", in your require section of composer.json, it just doesn't load it. So I had to run 'global require' again to install that mystery package globally, and then I could run composer install to get everything fresh, and it worked.
