如何解决：orderly/paypal-ipn-bundle dev-master 的安装请求 -> orderly/paypal-ipn-bundle[dev-master] 可满足

Question

我正在安装 Symfony 项目，运行 composer install 时出现以下错误：

我在那里寻找过，通常建议更新 symfony 版本，但我无法更新它。另外，该项目正在其他设备上使用相同的composer.json

rick@mint:~/repos/myvitale$ composer install
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 orderly/paypal-ipn-bundle dev-master -> satisfiable by orderly/paypal-ipn-bundle[dev-master].
    - Conclusion: don't install symfony/symfony v2.8.52
...
...
    - Conclusion: don't install symfony/symfony v2.8.2
    - don't install symfony/var-dumper v3.0.0|don't install symfony/symfony v2.8.0
    - don't install symfony/var-dumper v3.0.1|don't install symfony/symfony v2.8.0
...
...
...
    - orderly/paypal-ipn-bundle dev-master requires symfony/symfony >=2.0.12 -> satisfiable by symfony/symfony[v2.8.0, v2.8.1, v2.8.10,...  ....].
    - Conclusion: don't install symfony/symfony v2.8.1
    - Installation request for symfony/var-dumper ^3.0 -> satisfiable by symfony/var-dumper[v3.0.0, v3.0.1,

这是我的 composer.json

这发生在 USB 实时持久化中 ¿ 这重要吗？

Answer 1

您尝试安装的捆绑包似乎没问题，在查看here 时，您可以看到捆绑包的所有要求都已满足。

这可能是尝试使用的 PHP 版本的问题。检查正在使用的版本并确保它是正确的（我猜应该是 5.6.40，因为您使用的是 Symfony 2.8）。然后在 composer.json 的 require 部分添加 "php": ">=5.3.9,<6" 以限制可安装的版本。

还要在 composer.json (documentation) 的配置部分添加应该使用的平台（PHP 版本）。

"config": {
    "platform": {
        "php": "5.6.40"
    }
},

您可能还需要使用composer update 命令才能使其生效并应用于composer.lock 文件。

Answer 2

symfony/symfony 软件包已包含 VarDumper 组件（您尝试使用 symfony/var-dumper 软件包安装该组件）。这是 Composer 在旧版本中错误允许的内容，在 Composer 1.7.3 中已修复。

您真的需要版本 3.0.x 中的 VarDumper 组件吗？如果是这种情况，您需要先删除 symfony/symfony 并明确要求所有需要的组件。
