Question

有没有办法在运行composer install时禁用“不明确的类解析”警告？

我使用的包在不同的文件夹中具有相同名称（和命名空间）的类。

我知道this bug，但事实并非如此，因为这些类实际上是供应商的两倍。我无法做任何事情。

我也知道--no-autoloader标志当然不会抛出警告，只是因为它会跳过自动加载器生成。

找到了解决方案，虽然不是那么明显。写了about it here。

当使用paypal / merchant-sdk-php composer软件包并运行composer install或composer update时，你会收到很多警告信息，如下所示：

Github上已经有一个针对此问题的错误提示，但它似乎没有以高优先级处理（因为它于2014年7月31日开放）。

搜索了一段时间后，我找到了问题的根源，即/被称为PPAutoloader和PayPalAPIInterfaceService。每个API类都被复制到PayPalAPIInterfaceService中。它用于示例（它们是程序包的一部分），如果没有vendor / autoload.php可用，则加载PPAutoloader。但是这个内部逻辑（必须调用自动加载器）与“作曲家自动加载器生成过程”无关，该过程贯穿所有文件夹并构建它自己的配置。

那么解决方案是什么？

无法从自动装带器生成过程中排除文件夹（在供应商文件夹中）。当然，您可以使用--no-autoloader标志运行composer。但是你需要自己处理自动加载，这对于“仅”产生警告的问题来说有点激烈。

在这种情况下，有一种更简单的方法。由于此类仅与示例（系统中未使用）相关，因此我可以删除该文件。

为此，我使用composer.json的脚本部分和pre-autoload-dump命令事件（在自动加载器生成过程之前触发）。该命令删除包含PayPalAPIInterfaceService的services文件夹。

"scripts": {
    "pre-autoload-dump": [
        "rm -rf vendor/paypal/merchant-sdk-php/lib/services"
    ]
},

Answer 2

不是从vendor目录中删除文件（应避免使用），最好将带有歧义类的文件/ direactories添加到composer.json中的exclude-from-classmap部分：

"autoload": {
    ...
    "exclude-from-classmap": [
        "vendor/somevendor/somepackage/directory/with/ambiguous/classes/",
        "vendor/somevendor/somepackage/src/AmbiguousClass.php"
    ]
},

然后Composer将在生成类映射时忽略这些文件。

删除 vendor 目录并运行 composer install 为我消除了错误。
