python - Qt 调试器在 mac 上使用错误的 python 版本

Question

我使用的是 macOS Mojave 10.14.6。我的Qt版本是5.13.1。我的 Qt Creator 版本是 4.10.0。

当我设置断点并运行应用程序时，调试器永远不会完成并打印到调试器日志并显示以下错误。

因此，据我所知，lldb 使用了错误的 python 版本。这是 Qt Creator 设置还是 Mac 设置？我该如何修复它？

Answer 1

作为快速修复，请在终端中运行此命令:

defaults write com.apple.dt.lldb DefaultPythonVersion 2

问题是 lldb 的默认版本现在是 Python 3。这导致了 Qt 的一些问题，希望很快就能得到解决:
