composer报错整理

一、composer require guzzlehttp/guzzle报错Your requirements could not be resolved to an installable set of
提示组件不能被安装，搜了下说是版本不兼容。

- The package is not available in a stable-enough version according to your minimum-stability settingsee <.md#minimum-stability> for more details.Read <.md> for further common problems.Installation failed, reverting ./composer.json to its original content.

 
解决办法：在composer.json中添加以下
“minimum-stability”: “dev”, //这个遇上require时完全可以用上

[xc@iZ19999xdnwm akm]$ vim composer.json
{"minimum-stability": "dev",//要加在require上一级才能生效，如果require里面已经有了guzzlehttp/guzzle的版本，也要删掉。"require": {"overtrue/wechat": "~3.1","hanson/vbot": "^1.0","snowair/phalcon-debugbar": "^1.1","phpoffice/phpexcel": "^1.8","symfony/dom-crawler": "^3.3","khanamiryan/qrcode-detector-decoder": "^1.0","alchemy/zippy": "^0.4.8","guzzlehttp/guzzle": "^6.2@dev"//这一行是安装成功后生成的，可以忽略}
}

执行命令会先remove旧版本，然后install新版本，这一步过程我没有截图。贴出成功后的输出。

[xc@iZ19999xdnwm akm]$ composer require guzzlehttp/guzzle

二、composer太慢了?换国内镜像

composer config -g repo.packagist composer
