Answer 1

You should delete composer asset plugin :

• Linux : rm -rf ~/.composer/vendor/fxp
• Windows : rm -r %APPDATA%\Composer\vendor\fxp

And re-install it :

composer global require "fxp/composer-asset-plugin:~1.1.1"

Answer 2

Try this, I had the same error with an old version (existing folder) of the plugin:

$ composer global update

or if the global update doesn't work, you can remove manually the global installation folder of this plugin in C:\Users\$USERNAME\AppData\Roaming\Composer\vendor\fxp\composer-asset-plugin and reinstall the plugin by running the command:

$ composer global update

Answer 3

Following Federico advice what I've done is the following

rm -rf /root/.composer/*
composer global require "fxp/composer-asset-plugin:~1.0"

And now everything works fine.
