工作服 UnicodeDecodeError

Question

我在tox中有如下配置：

[tox]
envlist = py37

[testenv]
passenv = TRAVIS TRAVIS_*
setenv =
    DEFAULT_FROM = mock_email@mock.com
    DEFAULT_SERVER = mock_server
basepython =
    py37: python3.7
deps =
    -r{toxinidir}/requirements.txt
    -r{toxinidir}/test-requirements.txt
    nose
    pytest
    pytest-cov
sitepackages = False
commands =
    pytest {posargs} --cov
# Add the following line locally to get an HTML report --cov-report html:htmlcov-py37

以及以下 .coveragerc 文件：

[run]
branch=True
source=sync2jira/
omit=sync2jira/mailer.py

[report]
fail_under=60

但无论如何（即使在 Travis 中）python-coveralls 似乎无法将数据发送到 coveralls。我收到以下错误：

Submitting coverage to coveralls.io...

During handling of the above exception, another exception occurred:

知道我为什么会收到此错误吗？我也尝试过 coverage 而不是 pytest 但没有运气。

Answer 1

您使用的 coverage 主版本可能与您的 pytest and/or pytest-cov 版本不兼容。请确保如果您使用的是 12 月 14 日刚刚发布的 coverage 5.0，那么您也在使用这些其他模块的最新版本。

你能分享你的requirements.txt吗？

Answer 2

在我的例子中删除项目的 .tox 隐藏文件夹并重新运行 tox 工作。

我看到了：

report installed: coverage==4.5.4

我现在看到：

report installed: coverage==5.0.3
