在 vscode 中调试 pytest unittest 导致 AttributEerror sys has no attribute __breakpointhook__ on exit
Debugging pytest unitest in vscode results in AttributError sys has no attribute __breakpointhook__ on exit
我在 Ubuntu 18.04 和 Anaconda 版本 4.5.10 上使用 visual studio 代码 1.27.2 来管理我的虚拟环境。
我在 vscode 中安装了 Anaconda 和 python 扩展。
我使用虚拟环境进行了简单测试，其中我只为 python 3.6 安装了 pytest 和 pylint。
如果我运行这个简单的脚本：
import pytest
def test_test():
assert True == True
Visual Studio 代码 运行 测试完全正常并在输出控制台中显示结果。
如果我尝试调试此脚本，但是，测试 运行s 并在退出时，我得到一个 AttributeError sys has no attribute __breakpointhook__ 我不明白为什么？难道我做错了什么？这是 Visual Studio 代码调试器或 pytest 集成的错误吗？

我有点迷路了，不知道下一步该去哪里搜索。当然，我仍然可以调试我的代码，因为只有在退出时才会发生异常，但我发现它很麻烦，我不知道这是 Visual Studio 代码还是我的配置的问题。
如有任何帮助，我们将不胜感激！
它是一个 bug in ptvsd，将在其下一个版本中修复，它将包含在下一个版本的 VS Code Python 扩展中。
