我正在尝试从 laravel 5.5 升级到 5.6。我一直在使用升级指南。
首先，我尝试将laravel/framework更新为5.6.*，phpunit/phpunit更新为~7.0。
这会产生错误Your requirements could not be resolved to an installable set of packages.
我明白这意味着什么，但是错误日志真的很难解析，我已经尝试了几个小时将composer.json文件更改为一组可安装的软件包。
我自己还没有解决这个问题，所以我来找你。也许你们中的一些人真的喜欢解决这些问题......
所以，我现在的composer.json，在其所有的荣耀中：
{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {
"php": ">=7.1",
"laravel/framework": "5.6.*",
"jenssegers/rollbar": "^1.4",
"doctrine/dbal": "~2.3",
"sensiolabs/security-checker": "^3.0",
"guzzlehttp/guzzle": "~6.0",
"mandrill/mandrill": "1.0.*",
"lcobucci/jwt" : "^3.1",
"predis/predis": "~1.0"
},
"require-dev": {
"fzaninotto/faker": "~1.4",
"mockery/mockery": "0.9.*",
"phpunit/phpunit": "~7.0",
"phpspec/phpspec": "~4.0",
"laravel/homestead" : "~4.0",
"symfony/dom-crawler": "3.1.*",
"symfony/css-selector": "3.1.*",
"filp/whoops": "~2.0"
}
}
和当前的错误：
➔ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

我真的希望有人能够破译作曲家在这里的含义。我也希望能够自己做到这一点，但似乎同一问题的所有其他解决方案实际上都是专门针对该composer.json的，而不是一般的答案。
对于这种情况，我必须执行以下操作：
- 我将
php更新为^7.1.3 -
sensiolabs/security-checker到^4.1 -
phpspec到~4.0 -
laravel/homestead~7.3 -
symfony/dom-crawler和symfony/css-selector^4.0 - 删除对
composer optimize的引用，因为现在已删除 - 停止使用
configureMonologUsing(...)并为滚动条创建自定义记录器类。
