确定开发环境没有问题，因为本来可以截图，后来突然开始报错，重启开发者工具甚至重启电脑都没用。使用 node repl 就可以复现，但只在我的电脑上有问题，由于问题与代码无关，无法提供复现步骤。 报错内容：Error: fail to capture screenshot 操作步骤与详细报错如下。 > const automator = require('miniprogram-automator') undefined > automator.launch({ ... projectPath: ...

如题，真机打开体验版小程序，如果不开调试模式的话，转发出去的分享卡片没有使用指定的 imageUrl 而是截图，开了调试就一切正常。图片用的 cdn 域名已经配置了。 还有个有点相关的问题，不开调试模式，小程序不会使用手机本地时间。这个之前不会，是最近新的变动么，在哪里能看到变更日志呢。
