Python Qt Creator无法启动调试器 C++ Quest+Que+在QT创建者3.4.1下成功构建。但当我无法启动调试器时。应用程序输出中的输出：

调试开始

调试失败

调试已完成

调试器从未真正启动

终端中的输出：

当我用源代码安装gdb时，我没有附加--with python选项。我用谷歌搜索出有人使用该选项进行了构建，但什么也没发生。

终端中的输出暴露了两个问题：

ImportError:没有名为importlib的模块

导致Python中不支持的库。因此，正如@Amartel所说，安装新版本的Python（大于2.7）。但在我的情况下，gdb需要使用--with Python配置选项重建，以使gdb使用更新版本的Python

Python异常没有名为gdb的模块：
/usr/local/bin/gdb'

可以通过复制目录中的文件来解决：

gdb\u src\u dir/gdb/data directory/python/gdb

到

/usr/local/share/gdb

。注意：我的gdb安装在

/usr/local/bin

下

最后，调试器工作正常

但是，我没有得到问题2的原因。任何人都可以解释，安装了Amartel Python2.7的“2.7版中的新版本”和“导入导入导入库”

，在Python交互模式下是成功的。但是Qt创建者仍然报告相同的错误。默认的python命令现在指向Python2.7。我不确定为什么QTCreator想要启动python调试器，但看起来您缺少它。试着运行python-mpdb，看看能得到什么。如果您在Linux上，可能需要安装某种python-devel包。@Amartel向前迈出了一小步：GDB使用python2.6，尽管已经安装了python2.7。我应该用--with python选项重建gdb吗？您手动构建过gdb吗？如果是-那么是的，尝试重建它。另外，我在这里得到的关于您问题的大部分信息：

gcc used by qt creator : version 5.0.1
gdb used by qt creator : version 7.9

python 2.6.6 installed on my CentOS 6.5 ,and is in PATH .
