symfony - 资产：转储失败，“.pull-right is undefined: line: 60”

Question

我试图在本地安装字形图标，而不是从 CDN 中提取（由于我没有调查的原因，CDN 已停止显示它们）。现在运行assetic:dump会导致异常，我不知道如何修复：

me@server:/var/www/blah$ php app/console assetic:dump -vvv
Dumping all dev assets.
Debug mode is on.

}

任何意见是极大的赞赏！

Answer 1

原来这是lessphp中的一个错误：https ://github.com/leafo/lessphp/pull/478

目前解决方案是将composer.json中的版本更改为：

"require": {
    "leafo/lessphp": "dev-master#85bd4557920d5f4fcbf41beb621e91b842e3621b"
}

但显然这只是暂时的。感谢 freenode 上#symfony 中的milka！

Answer 2

我很确定我遇到了这个问题，并确定这是因为 Bootstrap LESS 在单独的文件中定义了变量，而 Assetic LESS 编译器不能很好地处理在不同文件中定义的变量。

Answer 3

在github上查看这个报告的错误。看起来;最后缺少的压缩文件导致了这种行为。一种解决方案是手动添加它。

我建议的解决方案是使用未压缩的文件来防止这种情况，并且在您的dev环境中也有更多可读的代码。对于prod环境，文件无论如何都会被资产压缩。
