Silvestripe 4.4 無法安裝 omnipay/paypal

Question

使用silverstripe 4.4 和silvershop，我嘗試了一百種變體來安裝omnipay/paypal和composer。

無論我嘗試什么，它都不會安裝。

有沒有人讓它與 ss4.4 一起工作？

怎么了？

Answer 1

根據您的錯誤消息，您缺少包php-http/client-implementation 。

如果您從Packagist快速瀏覽一下，您會發現該包實際上是一個虛擬包，因此您需要其中一個將自身定義為php-http/client-implementation ，因為它不是真實的包，你必須選擇一個。

如果您不知道該選擇哪個，請從Packagist 中選擇第一個。
值得一提的是，我過去實際上對狂飲套餐有很好的印象，所以我會說這是一個安全的賭注。

所以你可以通過做來解決你的問題

composer require php-http/guzzle6-adapter

然后運行

composer require omnipay/paypal

或者您甚至可以一次性完成：

$ composer require php-http/guzzle6-adapter omnipay/paypal
composer require php-http/guzzle6-adapter omnipay/paypal
Using version ^2.0 for php-http/guzzle6-adapter
