问题

拷贝来一个别人的clion工程，打开 出现以下错误：

Cannot generate into D:\all_projects\cpp_projects\test_queue
It is already used for project \home\leozhou\Public\test_queue
Please either delete it manually or select another generation directory

解决

在 clion idea中依次选择 Tools -> CMake -> Reset Cache And Reload Project
