我在尝试composer install我的依赖项时出错。与composer update相同的错误。
它说symfony/web-server-bundle 4.3.3和symfony 3.4之间存在冲突，但这些包应该是兼容的：
- https://github.com/symfony/web-server-bundle/blob/4.3/composer.json
- https://packagist.org/packages/symfony/web-server-bundle
这是我的控制台输出：
$ composer install --ignore-platform-reqs
Deprecation warning: Your package name theredled/. is invalid, it should have a vendor name, a forward slash, and a package name. The vendor and package name can be words separated by -, . or _. The complete name should match "[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9]([_.-]?[a-z0-9]+)*". Make sure you fix this as Composer 2.0 will error.
Deprecation warning: require.beberlei/DoctrineExtensions is invalid, it should not contain uppercase characters. Please use beberlei/doctrineextensions instead. Make sure you fix this as Composer 2.0 will error.

Problem 1
- Installation request for symfony/symfony v3.4.30 -> satisfiable by symfony/symfony[v3.4.30].
- don't install symfony/web-server-bundle v4.3.3|don't install symfony/symfony v3.4.30
- Installation request for symfony/web-server-bundle v4.3.3 -> satisfiable by symfony/web-server-bundle[v4.3.3].

知道吗？
正如我最近在另一个答案中所描述的那样，您确实会收到此错误消息，因为symfony/symfony充当完全相同版本的symfony/web-server-bundle的替代品，因为以下行：https://github.com/symfony/symfony/blob/3.4/composer.json#L85
作曲家文档准确地告诉你这一点，并以Symfony为例来解释replace部分：
这对于包含子包的包也很有用，对于 示例主 Symfony/Symfony 包包含所有 Symfony 组件也可作为单独的软件包提供。如果你 需要主包，它将自动满足任何要求 其中一个单独的组件，因为它替换了它们。
资料来源：https://getcomposer.org/doc/04-schema.md#replace
因此，就目前composer.json而言，您正在指示作曲家在版本4.3.3上安装symfony/web-server-bundle并在版本3.4.30上安装symfony/web-server-bundle(通过请求在版本3.4.30上安装symfony/symfony，这说明它替换了该包(，而作曲家最终处于不兼容状态， 正如错误所解释的那样，同时安装两个不同版本的软件包。
- don't install symfony/web-server-bundle v4.3.3|don't install symfony/symfony v3.4.30
- Installation request for symfony/web-server-bundle v4.3.3 -> satisfiable by symfony/web-server-bundle[v4.3.3].
=>不要安装symfony/web-server-bundle就是它的真正含义：你实际上不需要它，它已经是symfony/symfony的一部分
从这里您有三种选择：
- 您删除了
composer.json中对symfony/web-server-bundle的要求(但这意味着您必须按照symfony/symfony提供的版本3.4.30使用该软件包( - 您将
symfony/symfony包升级到4.3.3(仍然将symfony/web-server-bundle的要求排除在composer.json之外，因为symfony/symfony确实会替换它(。 您需要一个接一个地需要的
symfony/*包，但不是通过"超级包"symfony/symfony
。从长远来看，这是更多的工作和更多可能的不兼容性，但这是在版本^4.0中仍然具有其他Symfony软件包时symfony/web-server-bundle的唯一方法^3.0。
这方面的一个例子是替换composer.json的这一行："symfony/symfony": "3.4.*",跟
"symfony/asset": "3.4.*", "symfony/browser-kit": "3.4.*", "symfony/cache": "3.4.*", "symfony/class-loader": "3.4.*", "symfony/config": "3.4.*", "symfony/console": "3.4.*", "symfony/css-selector": "3.4.*", "symfony/dependency-injection": "3.4.*", "symfony/debug": "3.4.*", "symfony/debug-bundle": "3.4.*", "symfony/doctrine-bridge": "3.4.*", "symfony/dom-crawler": "3.4.*", "symfony/dotenv": "3.4.*", "symfony/event-dispatcher": "3.4.*", "symfony/expression-language": "3.4.*", "symfony/filesystem": "3.4.*", "symfony/finder": "3.4.*", "symfony/form": "3.4.*", "symfony/framework-bundle": "3.4.*", "symfony/http-foundation": "3.4.*", "symfony/http-kernel": "3.4.*", "symfony/inflector": "3.4.*", "symfony/intl": "3.4.*", "symfony/ldap": "3.4.*", "symfony/lock": "3.4.*", "symfony/monolog-bridge": "3.4.*", "symfony/options-resolver": "3.4.*", "symfony/process": "3.4.*", "symfony/property-access": "3.4.*", "symfony/property-info": "3.4.*", "symfony/proxy-manager-bridge": "3.4.*", "symfony/routing": "3.4.*", "symfony/security": "3.4.*", "symfony/security-core": "3.4.*", "symfony/security-csrf": "3.4.*", "symfony/security-guard": "3.4.*", "symfony/security-http": "3.4.*", "symfony/security-bundle": "3.4.*", "symfony/serializer": "3.4.*", "symfony/stopwatch": "3.4.*", "symfony/templating": "3.4.*", "symfony/translation": "3.4.*", "symfony/twig-bridge": "3.4.*", "symfony/twig-bundle": "3.4.*", "symfony/validator": "3.4.*", "symfony/var-dumper": "3.4.*", "symfony/web-link": "3.4.*", "symfony/web-profiler-bundle": "3.4.*", "symfony/workflow": "3.4.*", "symfony/yaml": "3.4.*"我刚刚通过复制
symfony/symfonycomposer.json的replace部分来创建的，其中我用您的实际symfony/symfony版本替换了"self.version"，最后，删除了软件包symfony/web-server-bundle，因为您已经在另一个版本上需要它。
至于你对symfony/web-server-bundlercomposer.json的误解，这个包确实与列出的Symfony版本^4.0的包兼容：
- symfony/config
- Symfony/console
- symfony/dependency-injection
- symfony/http-kernel
- Symfony/Polyfill-ctype
- symfony/process
但不是捆绑的"超级包"symfony/symfony，这确实不存在于其composer.json的要求部分中
