我正在用virtualenv在vscode中运行一个python项目。 Python解释器已正确设置。当我尝试发现测试时，它会提示我一个错误

python /Users/user/.vscode/extensions/ms-python.python-2019.10.44104/pythonFiles/testing_tools/run_adapter.py discover pytest -- -s project/
Test Discovery failed: 
Error: spawn /Users/<username>/apps/project/venv/bin/python ENOENT

我的vscode settings.json看起来像这样，但我尚未配置launch.json

{
    "python.pythonPath": "/Users/<username>/apps/project/venv/bin/python","python.testing.unittestEnabled": false,"python.testing.nosetestsEnabled": false,"python.testing.pytestEnabled": true,"python.testing.pytestArgs": [
        "project"
    ],}

当我在终端python shell上输入/Users/<username>/apps/project/venv/bin/python时打开。

ENOENT通常表示这是无效路径，但该路径看起来很正常。

$echo $PATH
/Users/<username>/apps/project/venv/bin
