安装包时出错（安装失败，正在将 ./composer.json 恢复到其原始内容。）

Question

我想安装一个带有“composer require rpsimao/invoicexpress-api”的包，但出现错误：

Using version ^0.5.6 for rpsimao/invoicexpress-api
./composer.json has been updated
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
    - Installation request for rpsimao/invoicexpress-api ^0.5.6 -> satisfiable by rpsimao/invoicexpress-api[0.5.6].
    - rpsimao/invoicexpress-api 0.5.6 requires laravel/framework 5.4.* -> satisfiable by laravel/framework[5.4.x-dev, v5.4.0, v5.4.1, v5.4.10, v5.4.11, v5.4.12, v5.4.13, v5.4.14, v5.4.15, v5.4.16, v5.4.17, v5.4.18, v5.4.19, v5.4.2, v5.4.20, v5.4.21, v5.4.22, v5.4.23, v5.4.24, v5.4.25, v5.4.26, v5.4.27, v5.4.28, v5.4.29, v5.4.3, v5.4.30, v5.4.31, v5.4.32, v5.4.33, v5.4.34, v5.4.35, v5.4.36, v5.4.4, v5.4.5, v5.4.6, v5.4.7, v5.4.8, v5.4.9] but these conflict with your requirements or minimum-stability.


Installation failed, reverting ./composer.json to its original content.

你知道如何解决吗？我使用的是laravel 5.5，该包似乎支持该版本，但出现错误。

Answer 1

即使他们说用 Laravel 5.5 进行了测试。* 在自述文件中，composer.json 说它需要两者

\n

"laravel/framework": "5.4.*",\n"illuminate/support": "5.4.*",\n

\n

所以如果包的composer.json说它应该是Laravel 5.4.*。您使用的是 laravel 5.5，因此它不兼容。

\n

这是标签 0.5.6 的rpsimao/invoicexpress-apicomposer.json文件。查看 Laravel 版本

编辑后

\n

因此，目前无法与 Laravel 5.5 一起使用，因为 Laravel 5.5 也使用 PHP >=7.0.0，此包使用 Laravel 5.4，而 Laravel 5.4 使用 PHP >=5.6.4。

并删除co​​mposer.lock文件（如果存在）
