miniprogram-automator 截图失败

框架类型 问题类型 操作系统 工具版本
小程序 Bug macOS RC 1.03.2006091

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:
... '/Users/username/dev/wxa-dcp/dist'
... }).then(mpp => global.mpp = mpp)
Promise { <pending> }

# 不带 options 报错

> mpp.screenshot()
Promise { <pending> }

      2.9.4 清除缓存后可以了,但是这个问题是怎么导致的,会不会自动化脚本跑久了出问题就要手动清一次。这就成半自动了啊。。。不会再加个清除缓存的接口吧😂
