Qt Quick Project with Qt Charts - 程序意外完成

如何解决Qt Quick Project with Qt Charts - 程序意外完成

问题：当我在包含条形图的情况下运行时程序崩溃（我从 QTCreator 构建和运行）。 条形图通过设计模式添加到矩形内。

操作系统：Ubuntu 20.04

安装方式：在线安装

QT Charts的安装方法：我通过QT维护工具和apt安装。

CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the
# deprecated API to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so,uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
