Python 在vscode中调试pytest unitest会导致AttributeError sys在退出时没有属性

我使用Ubuntu 18.04上的visual studio代码1.27.2和Anaconda版本4.5.10来管理我的虚拟环境

我在vscode中安装了Anaconda和python扩展

我使用一个虚拟环境进行了一个简单的测试，在这个虚拟环境中，我只安装了Pythest和pylint for python 3.6

如果我运行此简单脚本：

import pytest

def test_test():
    assert True == True

VisualStudio代码可以完美地运行测试，并在输出控制台中显示结果

但是，如果我尝试调试这个脚本，测试运行并在退出时得到一个AttributeError sys没有属性，我不明白为什么？我做错什么了吗？这是VisualStudio代码调试器或pytest集成的错误吗

堆栈跟踪：

我尝试在launch.json中使用此配置从调试会话运行它，但它给出了相同的堆栈跟踪和错误

{
     "name": "Debug Pytest",
     "type": "python",
     "request": "launch",
     "stopOnEntry": false,
     "pythonPath": "${config:python.pythonPath}",
     "module": "pytest",
     "envFile": "${workspaceFolder}/.env",
     "console": "integratedTerminal",
}

我有点迷路了，不知道下一步该去哪里找。当然，我仍然可以调试代码，因为只有在退出时才会发生异常，但我发现这很麻烦，我不知道这是Visual Studio代码还是配置的问题

任何帮助都将不胜感激

这是一个将在下一版本中修复的问题，该问题将包含在下一版本的Python VS代码扩展中

     "name": "Debug Pytest",
     "type": "python",
     "request": "launch",
     "stopOnEntry": false,
     "pythonPath": "${config:python.pythonPath}",
     "module": "pytest",
