I'm quite new with laravel and wrote my first app. I'm using Laravel 5.4 with PHP 7.1.5 but when I run the "composer require barryvdh/laravel-dompdf" command, I get following issues. I have followed many "possible solutions" but still it is not working. Oh, BTW, I'm using windows This is the error :
我对 Laravel 很陌生，并编写了我的第一个应用程序。我将 Laravel 5.4 与 PHP 7.1.5 一起使用，但是当我运行“composer require barryvdh/laravel-dompdf”命令时，出现以下问题。我遵循了许多“可能的解决方案”，但仍然无法正常工作。哦，顺便说一句，我正在使用 Windows 这是错误：
Your requirements could not be resolved to an installable set of packages.
无法将您的要求解析为一组可安装的软件包。
Problem 1 - Installation request for barryvdh/laravel-dompdf ^0.8.1 -> satisfiable by barryvdh/laravel-dom pdf[v0.8.1]. - barryvdh/laravel-dompdf v0.8.1 requires dompdf/dompdf ^0.8 -> satisfiable by dompdf/dompdf[v0. 8.0, v0.8.1, v0.8.2] but these conflict with your requirements or minimum-stability.
问题 1 - barryvdh/laravel-dompdf ^0.8.1 的安装请求 -> barryvdh/laravel-dom pdf[v0.8.1] 可满足。- barryvdh/laravel-dompdf v0.8.1 需要 dompdf/dompdf ^0.8 -> 可满足 dompdf/dompdf[v0. 8.0, v0.8.1, v0.8.2] 但这些与您的要求或最低稳定性相冲突。

Don't composer update. If you have dompdf/dompdfin your composer.json just update it, specifying 0.8.*as version and running
不要composer update。如果你dompdf/dompdf在 composer.json 中更新它，指定0.8.*版本并运行
composer update dompdf/dompdf
composer update dompdf/dompdf
then
然后
composer require barryvdh/laravel-dompdf
composer require barryvdh/laravel-dompdf

Running a generic composer updatewill affect all your other dependencies you may want keep as they currently are.
运行泛型composer update将影响您可能希望保持当前状态的所有其他依赖项。
All the changes affected by your composer updatecommand are then recorded in your composer.lock file.
所有受您的composer update命令影响的更改都会记录在您的 composer.lock 文件中。
When you'll move your project somewhere else or you'll deploy it on a server for example, the composer installcommand will read the composer.lock file and will install the exact version of your dependencies which are recorded in it. So you'll be sure about the version of your dependencies.
例如，当您将项目移动到其他地方或将其部署在服务器上时，该composer install命令将读取 composer.lock 文件并安装其中记录的依赖项的确切版本。因此，您将确定依赖项的版本。
