Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.

Installation failed, reverting ./composer.json to its original content.

Why there is no package found for wtf-8? Is it composer problem or I have something wrong with configuration?

[francoispluchino]

Strange, the packages in NPM registry are not loaded for wtf-8.

[francoispluchino]

Problem found... The driver initialization throws an exception. I fix this bug.

[francoispluchino]

The repository registred in NPM registry is https://github.com/mathiasbynens/wtf-8.js but this repository doesn't exist. On the other hand, the repository https://github.com/mathiasbynens/wtf-8 exist. It's for this reason that the driver isn't initialized.

@francoispluchino So to resolve this, should I contact with author of wtf-8 extension to update NPM registry?

[francoispluchino]

Why not! but I will init the registred packages in NPM registry before the initialization of the VCS driver.

[francoispluchino]

Registration of NPM registry packages fixed by 544b7a9.

But your dependency cannot be installed because the npm-asset/debug dependency is required by 2 another dependencies with 2 different versions (2.3.3 and 2.2.0).

I will add a dependency resolution feature to fix this problem (see #276).

[francoispluchino]

With the last 1.3.0@dev version of this plugin, your dependency can be installed with the resolutions feature:

{
    "require": {
        "npm-asset/socket.io": "^1.7.0"
    },
    "config": {
        "fxp-asset": {
            "resolutions": {
	        "npm-asset/debug": "^2.3.3",
                "npm-asset/component-emitter": "^1.2.1"
            }
        }
    }
}
