coverage.misc.NoSource：没有代码来源：'/usr/src/server/rep-1>'

Question

我使用 coverage 包已经有一段时间了，直到昨天它都运行良好，我相信它只是在生成报告的级别上失败了。更奇怪的是，功能没有变化。

我有以下 coveragerc 文件：

[run]
source = .
branch = True
concurrency = multiprocessing
omit =
    manage.py
    config/asgi.py
    config/wsgi.py
    config/settings.py
    */migrations/*
    *test*

[report]
show_missing = True
skip_covered = True

和Django manage.py文件如下：

import os
import sys


COVERAGE_ACCCEPTANCE = 85


def main():
    argv = sys.argv
    try:
        command = argv[1]
    except IndexError:
        command = "help"
    default_settings = "config.settings"
    running_tests = (command == "test")
    if running_tests:
        default_settings = "config.settings_test"
        from coverage import Coverage
        cov = Coverage()
        cov.erase()
        cov.start()
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", default_settings)
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?",
        ) from exc
    execute_from_command_line(argv)
    if running_tests:
        cov.stop()
        cov.save()
        cov.combine()
        if round(cov.report()) < COVERAGE_ACCCEPTANCE:
            sys.exit(1)
        cov.erase()


if __name__ == "__main__":
    main()

测试运行成功后，覆盖率引发以下错误：

我认为它所说的文件未找到 (/usr/src/server/rep-1) 可能是生成的报告，因为我的存储库中没有任何此类文件。我真的很感激任何见解，因为这有点奇怪，我在 GitHub/Whosebug 上的文档或包问题中找不到任何与此实例类似的内容。

我运行正在使用 Django 3.1，在 GitLab 管道上的覆盖率为 5.5。

我发现根本原因是今天发布了 attrs==21.3.0 库。如果我使用 21.2.0 版本，那么 coverage report 不会因为缺少表示文件而失败。
