QT学习之VS创建QT项目显示未将对象引用设置到对象的实例
2022-07-24 21:48:00 【点云学徒】
一、问题描述
想学习QT,结果刚创建QT项目就折戟沉沙,显示未将对象引用设置到对象的实例,没法创建,很奇怪我之前都能用,突然不能用了,只能百度百度,一上午过去了,各种什么注册表啊,什么什么的咱也看不懂,最后找到了下面这个方法。
二、解决方法
第一步:删除旧东西
C:\Users\hgq\AppData\Local\Microsoft\VisualStudio\16.0_e57de9d0
我是VS2019,所以是对应16,你可以对应15或者14之类的,反正就是它。
把这个16.0_e57de9d0文件夹删除
第二步:重新安装qt-vsaddin-msvc2019-2.6.0-rev.07.vsix插件
这个插件是我老早之前就下载过的,所以我直接安装了,如果你没有,可以去下载,再VS上搜索下载基本上是慢到没谱了。有当然最好,直接点一下就行。
