问题描述

某些原因导致本地故障。回滚到旧版本的代码库仍会返回相同的失败。删除整个存储库，重新克隆，卸载指南针，重新安装等仍然会产生相同的错误。

Something has caused a local failure. Rolling back to older versions of the codebase still return the same failure. Deleting the entire repo, re-cloning it, uninstalling compass, reinstalling, etc. still yields the same error.

推荐答案

我遇到了类似的问题。要复制-我从iconmostr下载一个图标并将其包含在我的sprites文件夹中。我遇到了同样的错误。重新启动后，等出现同样的错误。

I had a similar problem. To replicate - I download an icon from iconmostr and included it in my sprites folder. I got the same error. After rebooting, etc. same error.

解决问题的是在Photoshop中打开图标[CS5.5]，然后使用Interlace将图标重新保存为.png

What fixed the problem was opening the icon in Photoshop[CS5.5] and re-saving the icon as a .png with Interlace as "No."

图片元读取为该软件为 Adob​​e ImageReady，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）。

The image meta read that the software was "Adobe ImageReady" and there was no Profile Name (sRGB IEC61966-2.1 on the re-exported), no DPI (72 on re-exported), or Type (PNGf on the re-exported) saved.
