为了更好地理解这一点（简洁地说）：Compiled.php相当于现有应用程序的快照映射。作曲家更新能够更改快照中映射的类的位置或存在。发生这种情况时，compiled.php无法在其映射中找到类。（这就是为什么'clear-compiled'应该几乎总是在pre-update-cmd块中运行。）

此问题通常发生在升级或异常文件系统更改期间，这些更改实际上会使compiled.php无效。好消息是，有一种解决方法。

如果只是你的compiled.php搞砸了，你可以手动删除它并再次尝试编辑器更新。这通常使用“php artisan clear-compiled”完成，但由于工匠使用的是compile.php，因此该命令会阻止自身。因此需要手动删除compiled.php文件。

.grid-single .grid-content {
    position: absolute;
    width: 100%;
    height: 100%;
    top: 0;
    left: 0;
    background: #1ABC9C;
    opacity: 0;
    transition: opacity 0.1s;
    text-align:left;
}

.grid-single .grid-content span {
    display: table;
    position:absolute;
    left:10%;
    width:80%;
    height:100%;
    text-align:center;
}

.hover-content {
    display:table-cell;
    background-color:#ff6600;
    vertical-align:middle;
}

如果您仍然遇到有关缺少类的错误，则意味着您的文件系统中缺少其他地方所需的内容。下一部分有点棘手，但它确实有效。

基于我在你的composer.json文件中看到的内容，你可能需要将“php artisan clear-compiled”命令从'post-update-cmd'移到'pre-update-cmd '阻止。这样，在作曲家更新文件后，compiled.php文件不会像上面所描述的那样阻止工匠。

解除这种情况的完整过程是：

手动删除compiled.php（通常在L5.1的/ bootstrap / cache中）
确保在composer.json的“pre-update-cmd”块中没有运行工匠命令（具体来说，这不是问题）
运行composer update
在composer.json的“pre-update-cmd”块中放回任何删除的工匠命令（具体来说，只需将清除编译从post移到pre）

如果您有问题，请发表评论。

问题在于命名空间。我甚至没有意识到它是这样的，之前我使用过php artisan app:name myname，它更新了文件，但它没有更新composer.json文件。所以我还原了它改变命名空间的每个文件 - 现在它可以工作。

愚蠢但耗费时间......

L5.1 Class App \ Console \ Kernel不存在
