Composer：在服务器上找不到的包，但在本地计算机上找不到

Question

I have two identical composer.json on my local windows machine and my linux dev server:

"name": "yiisoft/yii2-app-advanced",
"description": "Yii 2 Advanced Project Template",
"keywords": ["yii2", "framework", "advanced", "project template"],
"homepage": "http://www.yiiframework.com/",
"type": "project",

    "irc": "irc://irc.freenode.net/yii",
    "source": "https://github.com/yiisoft/yii2"
},
"minimum-stability": "stable",
"require": {
    "php": ">=5.4.0",
    "yiisoft/yii2": "~2.0.6",
    "yiisoft/yii2-bootstrap": "~2.0.0",
    "yiisoft/yii2-swiftmailer": "~2.0.0",
    "yiisoft/yii2-jui": "^2.0",
    "kartik-v/yii2-widget-select2": "@dev",
    "2amigos/yii2-file-upload-widget": "~1.0",

},
"require-dev": {
    "yiisoft/yii2-debug": "~2.0.0",
    "yiisoft/yii2-gii": "~2.0.0",
    "yiisoft/yii2-faker": "~2.0.0",

    "codeception/base": "^2.2.3",
    "codeception/verify": "~0.3.1"
},
"config": {
    "process-timeout": 1800,
    "fxp-asset":{
        "installer-paths": {
            "npm-asset-library": "vendor/npm",
            "bower-asset-library": "vendor/bower"
        }
    }
}

On my local machine, I can update composer without any problems:

Yet on my server, I get the error that the packages could not be found:

$ composer update
You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug

    - Installation request for yiisoft/yii2 ~2.0.6 -> satisfiable by yiisoft/yii2[2.0.10, 2.0.11, 2.0.11.1, 2.0.11.2, 2.0.12, 2.0.6, 2.0.7, 2.0.8, 2.0.9, 2.0.x-dev].

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.

After quite some hours of searching around, I still don't have any clue where to even begin with. Any ideas?

Answer 1

Try adding this to the end of your composer.json:

"repositories": [
    {
        "type": "composer",
        "url": "https://asset-packagist.org"
    }
]

Since the server can't find any packages, there seem to be something wrong with the repository definition. Not sure, but in your local composer environment the repo above may have been defined outside of your composer.json (as a default perhaps).
