Question

我可以在travis构建日志中看到env变量正确导出：

Setting environment variables from .travis.yml
$ export K_API_KEY=[secure]
$ export K_PRIVATE_KEY=[secure]
$ export TOXENV=py27

但是在我的测试中没有选择它们使用基本的config.py文件，该文件应该以这种方式获取env变量（API_KEY = os.environ['K_API_KEY']），参见相关的travis日志：

$ source ~/virtualenv/python2.7/bin/activate
$ python --version
Python 2.7.9
$ pip --version
pip 6.0.7 from /home/travis/virtualenv/python2.7.9/lib/python2.7/site-packages (python 2.7)

我怀疑是我的tox.ini（见下文）没有选择那些变量，但不确定，不知道吗？

[tox]
envlist = py27, flake8
; envlist = py26, py27, py33, py34, py35

[flake8]
max-line-length= 100
exclude= tests/*

[testenv]
setenv =
    PYTHONPATH = {toxinidir}:{toxinidir}/pykraken
deps =
    -r{toxinidir}/requirements_dev.txt
commands =
    py.test --basetemp={envtmpdir}

Answer 1

正如@jonrsharpe指出的那样，解决方案是使用tox.ini中的passenv选项，如documentation

中所述

[testenv]
setenv =
    PYTHONPATH = {toxinidir}:{toxinidir}/pykraken
passenv =
    K_API_KEY
    K_PRIVATE_KEY

travis安全env变量未在tox中使用
