需求包文件版本错误

Question

构建环境时，需求包 synergine-0.0.1.9 中的一个文件似乎已过时。

.travis.yml

language: python
python:
  - "3.4"
install:
  - "pip install -r tests_requirements.txt --upgrade"
  - "pip install python-coveralls"
script:
  - coverage run tests.py --rcfile=.coveragerc -v && coverage report -m && python3.4 tests.py
after_success:
  - coveralls

tests_requirements.txt

synergine>=0.0.1
synergine_xyz>=0.0.1

travis-ci.org 构建日志：

[...]
pip 6.0.7 from /home/travis/virtualenv/python3.4.2/lib/python3.4/site-packages (python 3.4)
install.1

1.74s $ pip install -r tests_requirements.txt --upgrade

You are using pip version 6.0.7, however version 7.0.3 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

  File "/home/travis/virtualenv/python3.4.2/lib/python3.4/site-packages/synergine/core/simulation/MetaValue.py", line 19, in unset

    del (state[subject])

NameError: name 'state' is not defined

travis-ci 构建中的 synergine/core/simulation/MetaValue.py", line 19, in unset 是：

del (state[subject])

如果我们在 pypi 上查找 synergine/core/simulation/MetaValue.py", line 19, in unset：

del(metas[subject])

文件不相同。问题出在 travis-ci 缓存中？我该如何解决？

Answer 1

通过电子邮件与 travis-ci 支持讨论后，我们认为问题不是来自 travis-ci，而是可能来自 pypi（奇怪的 specific 缓存规则？） .
