Symfony 如何解决：有序/paypal ipn捆绑包的安装请求开发主机->；有序/paypal ipn捆绑包可满足[dev master]

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

我已经在那里找过了，通常建议更新symfony版本，但我无法更新它。此外，该项目正在使用相同的composer.json处理其他设备

这是在usb live persistente中发生的？这很重要吗？

您尝试安装的捆绑包似乎还可以，当查看时，您可以看到捆绑包的所有要求都已达到

---

尝试使用的PHP版本可能有问题。请检查正在使用的版本，并确保该版本是正确的（我猜应该是5.6.40，因为您使用的是Symfony 2.8）。然后添加

“PHP”：“>=5.3.9，
Symfony/Symfony
包已经包含VarDumper组件（您尝试使用
symfony/var dumper
软件包安装）。这是Composer在旧版本中错误地允许的，在Composer 1.7.3中已修复

您真的需要3.0.x版中的VarDumper组件吗？如果是这样，您需要先删除
symfony/symfony
