【中文标题】Composer 更新 - 您的要求无法解析为一组可安装的软件包

【英文标题】：Composer Update - Your requirements could not be resolved to an installable set of packages

【问题描述】：

我在解决这个问题时遇到了一个可怕的问题。我有一个 php 项目，正在尝试使用 composer 来更新项目（代码是给我更新的，我不是原始开发人员）。我运行更新并得到这个：

Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - suncat/mobile-detect-bundle dev-master requires mobiledetect/mobiledetectl
ib 2.7.* -> no matching package found.
    - suncat/mobile-detect-bundle dev-master requires mobiledetect/mobiledetectl
ib 2.7.* -> no matching package found.
    - Installation request for suncat/mobile-detect-bundle dev-master -> satisfi
able by suncat/mobile-detect-bundle[dev-master].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your min
imum-stability setting

or more details.

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

【参考方案1】：

我也遇到了同样的问题^^

来源：https://packagist.org/packages/suncat/mobile-detect-bundle

改变：

"mobiledetect/mobiledetectlib" : "dev-master",

收件人：

"mobiledetect/mobiledetectlib" : "2.7.*",
