小程序启动黑屏问题

本人遇到一个特别坑的问题，使用win7系统打开最新版（1.02.2004020）的微信开发工具，出现莫名黑屏。一开始认为是系统问题，重新安装系统后，还是无法打开开发工具，这就很奇怪了，同事的电脑也是win7系统，是可以正常运行的。经过搜索，分析后，终于锁定问题，下面是解决方案。

新建JSON文件

新建一个名为 localstorage_b72da75d79277d2f5f9c30c9177be57e 的json文件。

文件内容如下。

移动文件位置

将json文件移动到 ~/AppData/Local/微信开发者工具/User Data/WeappLocalData 文件目录下，重新启动微信开发者工具即可。
