Composer在Yii2 composer.json中找不到新需求的软件包

Question

Ok, I'm using Yii2 and I am trying to add a new requirement/library to the project. Said library can be found here: https://github.com/cyphix333/SBBCodeParser

It is a forked project with an added composer.json .

I tried adding it as a requirement in the projects main composer file, ie:

"require": {
    //..........
    "samclarke/sbb-code-parser": "*"
},

Then I ran:

composer update

It just complained that it couldn't find the package or any version of it.

Then I removed that line and tried:

require samclarke/sbb-code-parser

I have the files already in my Yii vendor folder located at: @app/vendor/samclarke/sbb-code-parser

I'm pretty new to composer and am not sure what I'm doing wrong or how composer actually is supposed to know where to get the files from based on the package name.

The package samclarke/sbb-code-parser can be found at Packagist. https://packagist.org/packages/samclarke/sbb-code-parser

By default Composer tries to resolve a stable set of packages. But this packages doesn't provide a stable version (version tag), yet - only the dev-master version exists. Composer can not resolve it. In order to require it, you need to lower your minimum-stability for this package to development.

You might do this for one package explicitly:

"require": {
    "samclarke/sbb-code-parser": "dev-master@dev"
},

Or for all packages by setting:

"minimum-stability": "dev"

The package cyphix333/SBBCodeParser is not on Packagist. It's a private fork. If you want exactly this code. You might add a repositories section to your composer.json and add repo with url and type with vcs there. Then Composer can load the package from the VCS repository over at Github. This is described here: https://getcomposer.org/doc/05-repositories.md#loading-a-package-from-a-vcs-repository

That would work like this:

{
    "repositories": [
        {
            "type": "vcs",
            "url": "https://github.com/cyphix333/SBBCodeParser"
        }
    ],
    "require": {
        "samclarke/sbb-code-parser": "dev-master"
    }
}

But unfortunately, the fork is also not well maintained and doesn't contain a valid composer.json file.

 [Composer\Repository\InvalidRepositoryException]
 No valid composer.json was found in any branch or tag of https://github.com/cyphix333/SBBCodeParser, could not load a package from it.

This needs to be fixed first....
