报错截图

Cause: 1.The hvigorVersion version (2.4.2) is not within the expected range 3.x.x 
(3.x.x >= 3.0.9). 2.The @ohos/hvigor-ohos-plugin version (2.4.2) is not within the 
expected range 3.x.x (3.x.x >= 3.0.9). 
Solution: Change the values of 
hvigorVersion to 3.0.9 and @ohos/hvigor-ohos-plugin to 3.0.9, while updating the 
command line script hvigor-wrapper.js that matches hvigor, which will auto-install
 the respective versions of the tools. Then sync the project again.
 

报错原因

日志中已经明显给出了，报错是 hvigorVersion 版本差异导致的，产生这个问题之前的操作是导入项目到DevEcho Studio中。由于IDE版本差异，原项目是基于 DevEcho Studio 3.x 构建的，导入到 DevEcho Studio 4.x 中而出现的问题。

报错解决

同样日志中也给出了解决方案：

**升级hvigorVersion **，然后再次同步项目。

也就是点击报错截图中蓝色链接即可

再次构建就能正常运行了
