無法安裝 symfony/maker-bundle

Question

我是 Symfony 的新手，我嘗試安裝symfony/maker-bundle ，但它給了我以下錯誤：

Using version ^1.22 for symfony/maker-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "4.4.*"
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - ocramius/proxy-manager 2.9.0 requires composer-runtime-api ^2.0.0 -> no matching package found.
    - ocramius/proxy-manager 2.9.0 requires composer-runtime-api ^2.0.0 -> no matching package found.
    - ocramius/proxy-manager 2.9.0 requires composer-runtime-api ^2.0.0 -> no matching package found.
    - Installation request for ocramius/proxy-manager (locked at 2.9.0) -> satisfiable by 
ocramius/proxy-manager[2.9.0].

我搜索了類似的問題，他們經常在composer.json更改包版本作為解決方案，但是我在其中找不到ocramius/proxy-manager和composer-runtime-api ：

我可能需要其他版本的symfony/maker-bundle嗎？

Answer 1

Ocramius 以其在保持向后兼容性方面的嚴厲立場而聞名。

在這種情況下，版本 2.9.0說：

此版本升級ocramius/proxy-manager以使用composer-runtime-api:^2 ：這意味着您將需要composer:^2來安裝此版本的 ProxyManager。

為了升級到 composer v2，您可以在您的開發或 CI/CD 系統上運行composer self-update --2 。

所以你的選擇是：

• 要么將 composer 升級到版本 2（ composer self-update --2 ），這確實是推薦的方法，除非您有一些您真正需要的特定 composer 插件並且尚未更新以適應新版本。

• 找到您正在安裝的軟件包是需要代理管理器的composer why ocramius/proxy-manager （ composer why ocramius/proxy-manager ），並查看您是否可以調整對該軟件包的版本限制，使其依賴於較舊的（< 2.9）版本ocramius/proxy-manager 。 （我提到這個選項只是為了完整起見，但升級作曲家確實是要走的路）。
