Python sphinx命令缺少conf文件

当我运行

tox

命令为我的Python项目生成

Sphinx

文档时，我遇到了问题。以下是错误：

docs runtests: PYTHONHASHSEED='1181019260'
docs runtests: commands[0] | sphinx-build -W -b html -c ./conf.py -d /Users/rakesh.kumar/ll/client-location/limekiln/.tox/docs/tmp/doctrees . /Users/rakesh.kumar/ll/client-location/limekiln/.tox/docs/tmp/html
Error: Config directory doesn't contain a conf.py file.
ERROR: InvocationError: '/Users/rakesh.kumar/ll/client-location/limekiln/.tox/docs/bin/sphinx-build -W -b html -c ./conf.py -d /Users/rakesh.kumar/ll/client-location/limekiln/.tox/docs/tmp/doctrees . /Users/rakesh.kumar/ll/client-location/limekiln/.tox/docs/tmp/html'
_________________________________________________ summary __________________________________________________
  py27: commands succeeded
  lint: commands succeeded
ERROR:   docs: commands failed

它基本上是在抱怨

conf.py

，但是这个配置文件存在于

tox.ini

所在的目录中。我是新来的

tox

和

sphinx

，不知道它为什么抱怨。 这是tox.ini的内容

[tox]
envlist = py27,lint,docs

[testenv]
commands =
    python setup.py nosetests --with-coverage --cover-package=limekiln --cover-erase --cover-html
    python setup.py sdist
deps =
    setuptools>=17.1

[testenv:docs]
basepython=python
changedir=docs
deps=sphinx
commands=
    sphinx-build -W -b html -c ./conf.py -d {envtmpdir}/doctrees .  {envtmpdir}/html

[testenv:lint]
commands=flake8 --max-line-length 99 limekiln
basepython=python2.7
deps=
    flake8
    flake8-print

这是我的

conf.py

文件

import sys, os

sys.path.insert(0, os.path.abspath('extensions'))

extensions = ['sphinx.ext.autodoc', 'sphinx.ext.doctest', 'sphinx.ext.todo',
                    'sphinx.ext.coverage', 'sphinx.ext.pngmath', 'sphinx.ext.ifconfig',
                                  'epub2', 'mobi', 'autoimage', 'code_example', 'sphinx.ext.autodoc']

todo_include_todos = True
templates_path = ['_templates']
source_suffix = '.rst'
master_doc = 'index'
exclude_patterns = []
add_function_parentheses = True
#add_module_names = True
#modindex_common_prefix = []

project = u'Limekiln'
copyright = u'2015'

version = '1.0'
release = '1.0'

这是我的项目的目录结构

Project-root-directory
├── conf.py
├── module directory
│   ├── module sub-directory1
│   ├── module sub-directory2
├── requirements.txt
├── setup.py
└── tox.ini

改变

commands=
sphinx-build -W -b html -c ./conf.py -d {envtmpdir}/doctrees .  {envtmpdir}/html

到

从sphinx构建帮助：

-c <path>           path where configuration file (conf.py) is located

-c配置文件（conf.py）所在的路径

意思是，这是文件夹路径，而不是配置文件路径。我试过了，但仍然出现相同的错误。

树/Users/rakesh.kumar/ll/client location/limekiln/.tox/docs/tmp/html错误：配置目录不包含conf.py文件。

它只在我指定绝对路径时对我有效。如果

tox.ini

和

conf.py

在同一目录中，为什么会有

changedir

指令？

-c <path>           path where configuration file (conf.py) is located
