当我执行 composer require laravel/passport 时，我得到了

Using version ^5.0 for laravel/passport ./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 laravel/passport ^5.0 -> satisfiable by laravel/passport[v5.0.0]. - Conclusion: remove laravel/framework v5.5.34 - Conclusion: don't install laravel/framework v5.5.34 - laravel/passport v5.0.0 requires illuminate/encryption ~5.6 -> satisfiable by illuminate/encryption[v5.6.0, v5.6.1, v5.6.2, v5.6.3]. - don't install illuminate/encryption v5.6.0|don't install laravel/framework v5.5.34 - don't install illuminate/encryption v5.6.1|don't install laravel/framework v5.5.34 - don't install illuminate/encryption v5.6.2|don't install laravel/framework v5.5.34 - don't install illuminate/encryption v5.6.3|don't install laravel/framework v5.5.34 - Installation request for laravel/framework (locked at v5.5.34, required as 5.5.*) -> satisfiable by laravel/framework[v5.5.34].

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

我认为这意味着我的 illuminate/encryption 版本与此版本的 laravel/passport 不兼容

这样对吗？解决此问题的最佳方法是什么？我什至不知道如何查看我拥有的 illuminate/encryption 版本。它不会出现在 composer show 中。

这是我的 composer.json

最佳答案

Passport 5.0 依赖于 Illuminate 包的 5.6 版。我可以看到你已经安装了 Laravel 5.5，所以要么将 Laravel 升级到 5.6，要么使用 Passport 的 4.0 分支。

Passport 存储库中 composer.json 的 “require” 部分已全部指定:

"require": {
    "php": ">=7.0",
    "firebase/php-jwt": "~3.0|~4.0|~5.0",
    "guzzlehttp/guzzle": "~6.0",
    "illuminate/auth": "~5.6",
    "illuminate/console": "~5.6",
    "illuminate/container": "~5.6",
    "illuminate/contracts": "~5.6",
    "illuminate/database": "~5.6",
    "illuminate/encryption": "~5.6",
    "illuminate/http": "~5.6",
    "illuminate/support": "~5.6",
    "league/oauth2-server": "^6.0",
    "phpseclib/phpseclib": "^2.0",
    "symfony/psr-http-message-bridge": "~1.0",
    "zendframework/zend-diactoros": "~1.0"
},

Illuminate 版本号与框架一致，因此 Laravel 5.6 将使用 Illuminate 5.6，5.5 将使用 Illuminate 5.5，等等。
