我报的是 errno = 1
压缩图片: /Users/duke/Downloads/bg.jpg

img_1664423934143.jpg 这个图片是不存在的，估计是压缩完后存放的文件名。 我是用的macos。

这个问题已经解决了，由于我开发的是desktop，所以需要文件系统的权限， 在macos中找到文件：DebugProfile.entitlements 将配置部分改为如下即可：
<key>com.apple.security.app-sandbox</key>
<false/>
<key>com.apple.security.cs.allow-jit</key>
<true/>
<key>com.apple.security.network.server</key>
<true/>
<key>com.apple.security.network.client</key>
<true/>
<key>com.apple.security.files.user-selected.read-only</key>
<true/>
<key>com.apple.security.files.user-selected.read-write</key>
