Compass 0.12中的Spriting错误/问题

时间：2012-06-25 21:19:22

标签： sass compass-sass

某些事情导致了局部失败。回滚到旧版本的代码库仍然会返回相同的故障。删除整个仓库，重新克隆它，卸载指南针，重新安装等仍然会产生相同的错误。

答案 0 :(得分：2)

我有类似的问题。要复制 - 我下载icon from iconmostr并将其包含在我的sprites文件夹中。我得到了同样的错误。重启后等同样的错误。

解决问题的方法是在Photoshop [CS5.5]中打开图标并将图标重新保存为带有Interlace的.png作为＆＃34; No。＆＃34;

图像元读取该软件是＆＃34; Adob​​e ImageReady＆＃34;并且没有配置文件名称（重新导出时为sRGB IEC61966-2.1），没有DPI（重新导出时为72）或类型（重新导出时为PNGf）已保存。

希望这有帮助。

答案 1 :(得分：1)

我也遇到过这个问题。这是由图像中的异常数据引起的 optipng the_pic报告了错误(Extraneous data found after IEND) optipng -fix the_pic解决了它，指南针快乐地编译。

P.S。我没有PhotoShop，错误图像来自我的设计师的PhotoShop（我猜是5.0）......似乎出口时出了问题。

答案 2 :(得分：0)

我得到了这个。对我来说，问题是由于Gemfile没有包含Compass gem而引起的。所以我刚补充说：

gem 'compass'

问题消失了。错误信息对于意识到这是问题非常无益。
