每次尝试运行 composer update 时都会收到以下错误：

您的要求无法解决为一组可安装的软件包。

问题 1 - 找不到请求的包原则/数据夹具 dev-master。

问题 2 - 找不到请求的包学说/教义固定装置捆绑开发主。

潜在原因：

这是我的composer.json：

奇怪，我复制并粘贴了您的 composer.json 并进行了“composer install”，并且没有问题地完成。

我的建议是确保作曲家是最新的（运行“作曲家自我更新”），然后可能尝试清除作曲家存储库缓存。缓存存储库曾经存在一个问题，报告分支不存在，但据说它已修复..

清除作曲家缓存（改编自下面的评论）：

在 *nix 机器上并在本地安装 composer 然后它应该在你的主目录中的“.composer/cache”中。

在带有本地作曲家的 *Nix 系统上：删除~/.composer/cache目录。
