要求不能解決到一個可安裝的套件組

Question

我試圖在laravel-starter-kit中安裝jasonlewis/enhanced-router軟件包，當我運行composer update時它不會安裝並出現一些錯誤。最初我以爲問題出自jasonlewis/enhanced-router（"jasonlewis/enhanced-router": "dev-master"）的作曲家專輯，但我刪除了它，並且出現了相同的錯誤。

我試圖尋找一些類似的問題，但無法弄清楚我得到的依賴關係問題是什麼。

下面是結果運行composer update後，我得到：

Answer 1

歡迎來到Composer最糟糕的功能！

所以問題是，你的依賴關係中有難以發現的衝突。

您在composer.json中需要"laravel/framework": "4.0.*",。你也有"zizaco/confide": "dev-master"

要求在github上的composer.json爲 'zizaco /吐露' 上我們看到：

「照亮/支持」： 「4.1.x的」，

造成您一個問題的作曲家功能是replace關鍵字全球經營包裝整體。

因此，當Composer試圖滿足「照明/支持」：「4.1.x」的要求時，它實際上試圖下載laravel 4.1.x版本。

與您對laravel 4.0版的要求衝突*，因此無法解決依賴關係集。

我認爲可能沒有小問題解決您的問題。

我打算建議指定早期版本的zizaco/confide而不是dev-master，這取決於照明/支持版本4.0.x而不是4.1.x--但是這意味着從zizaco/confide 3切換.x到2.x這可能是不可接受的。

唯一的其他選擇是將您的需求從laravel 4.0.x更改爲4.1。* - 這可能會或可能不會被接受，基於會導致您的工作量。
