php - Composer 无法安装 Twig Extensions

Question

我尝试在我的 Symfony 5 应用程序的 dev-master 版本中安装 twig/extensions 包。我遇到以下输出:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for twig/extensions dev-master -> satisfiable by twig/extensions[dev-master].
    - Conclusion: remove twig/twig v3.0.3
    - Conclusion: don't install twig/twig v3.0.3
    - twig/extensions dev-master requires twig/twig ^2.10 -> satisfiable by twig/twig[v2.10.0, v2.11.0, v2.11.1, v2.11.2, v2.11.3, v2.12.0, v2.12.1, v2.12.2, v2.12.3, v2.12.4, v2.12.5].
    - Can only install one of: twig/twig[v2.10.0, v3.0.3].
    - Can only install one of: twig/twig[v2.11.0, v3.0.3].
    - Can only install one of: twig/twig[v2.11.1, v3.0.3].
    - Can only install one of: twig/twig[v2.11.2, v3.0.3].
    - Can only install one of: twig/twig[v2.11.3, v3.0.3].
    - Can only install one of: twig/twig[v2.12.0, v3.0.3].
    - Can only install one of: twig/twig[v2.12.1, v3.0.3].
    - Can only install one of: twig/twig[v2.12.2, v3.0.3].
    - Can only install one of: twig/twig[v2.12.3, v3.0.3].
    - Can only install one of: twig/twig[v2.12.4, v3.0.3].
    - Can only install one of: twig/twig[v2.12.5, v3.0.3].
    - Installation request for twig/twig (locked at v3.0.3) -> satisfiable by twig/twig[v3.0.3].

作为package page似乎在其版本 ^2.10 中需要 twig/twig 我试图找到它在我的项目中有一个需要冲突的包(例如 ^3.0) 但似乎不存在:

$ composer why twig/twig
knplabs/knp-paginator-bundle  v5.1.1  requires  twig/twig (^2.0 || ^3.0)
symfony/twig-bridge           v5.0.4  requires  twig/twig (^2.10|^3.0)
symfony/twig-bundle           v5.0.4  requires  twig/twig (^2.10|^3.0)
symfony/twig-pack             v1.0.0  requires  twig/twig (^2.12|^3.0)
symfony/web-profiler-bundle   v5.0.4  requires  twig/twig (^2.10|^3.0)
twig/extra-bundle             v3.0.3  requires  twig/twig (^2.4|^3.0)

有人能告诉我为什么 Composer 不能解决我的要求吗？不要犹豫，要求输出更多评论。我会相应地对此进行编辑。

这里是我的 composer.json 的 require 和 require-dev 键:

"require": {
    "php": "^7.2.5",
    "ext-ctype": "*",
    "ext-iconv": "*",
    "antishov/doctrine-extensions-bundle": "^1.4",

看起来你的 twig 扩展包几乎已经被遗弃了!

来自包装师:

要求: Twig / Twig :^1.27|^2.0

在 dev-master 分支上:

要求: Twig / Twig :^2.10
