如何解決在composer.json中所需的4.1安裝和4.0相關軟件包之間的Laravel版本衝突

Question

我試圖安裝laravelodbc軟件包以與laravel框架一起使用。我最初使用composer create-project laravel/laravel --prefer-dist安裝laravel。然後我將"jtgrimes/laravelodbc": "0.2.*"添加到我的composer.json文件中，並將'jtgrimes\Laravelodbc\ODBCServiceProvider'添加到我在app.php中的提供者列表中。

我composer.json文件中的require關鍵是這樣的：

"require": { 
    "laravel/framework": "4.1.*", 
    "yajra/laravel-oci8": "*", 
    "jtgrimes/laravelodbc": "*" 
}, 

當我嘗試作爲laravelodbc readme建議運行composer update。

編輯 我與不同版本的laravel的試驗，看看是否能固定我的問題忘了改回來，當我張貼的問題。現在在上面顯示正確的laravel版本，並顯示如上所示的相同結果消息。

編輯2 我想你的建議，我的叉子是here（注意換到composer.json文件存在）。我也改變了composer.json文件在我laravel項目：

"require": { 
    "laravel/framework": "4.1.*", 
    "yajra/laravel-oci8": "*", 
    "Purkinje/laravelodbc": "*" 
}, 

...

"repositories": [ 
     { 
       "type": "vcs", 
       "url": "https://github.com/Purkinje/laravelodbc" 
     } 
], 

當我運行composer update，我得到的錯誤：

Problem 1 
    - The requested package purkinje/laravelodbc could not be found in any version, there may be a typo in the package name. 

Answer 1

如果您正在使用Laravel 4.1（由於你根據實際的4.1版本實例化了一個項目的安裝命令），你可能遇到一些版本衝突 - 4.1版本大約只有一個月左右。

請注意，在你 「jtgrimes/laravelodbc」 包composer.json文件你有

"illuminate/support": "4.0.x", 
       "illuminate/database": "4.0.x" 
    }, 

所以這是一個obvoius版本衝突，因爲你已經安裝了4.1。

速戰速決是隻創建一個基於Laravel 4.0一個新的項目，所以你可以很容易地安裝所有的包，而無需到餐桌他們在Github上

composer create-project laravel/laravel --prefer-dist your_project_name 4.0

另一種解決方法是用叉子叉在github上的項目，改變composer.json文件，包括4.1版本，比點你的作曲家從您的分叉版本上安裝，通過將參照混帳回購協議：記住

repositories": [ 
    { 
    "type": "git", 
    "url": "git://github.com/your-github-username/yourfork.git" 
    } 
] 

熊的4.0-> 4.1改變doe這意味着某些Laravel功能的使用會發生一些變化，所以在某些情況下，該軟件包可能無法按預期（或根本不能）在4.1使用情況下運行。有關詳細信息，請參閱laravel.com/docs/upgrade。
