构建project导入PyQt5的sphinx文档失败(build log)
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-docs'
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.
在tox.ini
中需要以下内容:
[testenv:docs]
# avoid QStandardPaths: XDG_RUNTIME_DIR not set
passenv = XDG_RUNTIME_DIR
# xvfb-run prevents Could not connect to any X display
commands = /usr/bin/xvfb-run sphinx-build --color -W -b html -d {envtmpdir}/doctrees . {envtmpdir}/html
如何在readthedocs上做到这一点?
这与PyQt 4 import in read-the-docs密切相关, 遗憾的是,它不包含错误消息。 PyQt5 可以从pip安装。
注意:
Install your project inside a virtualenv using setup.py install

也许mocking PyQT5可行。但这似乎有点cumbersome。
从this answer改编,添加
import mock
MOCK_MODULES = ['sip', 'PyQt5', 'PyQt5.QtGui', 'PyQt5.QtCore', 'PyQt5.QtWidgets']
sys.modules.update((mod_name, mock.MagicMock()) for mod_name in MOCK_MODULES)
到conf.py
收益
class _GRay(GCounterPart, QGraphicsPathItem):
TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
autodoc_mock_imports
更简单的错误(只有一行添加到conf.py
)
autodoc_mock_imports = ['sip', 'PyQt5', 'PyQt5.QtGui', 'PyQt5.QtCore', 'PyQt5.QtWidgets']
class Mock(object):
def __init__(self, *args, **kwargs):
pass
def __call__(self, *args, **kwargs):
return Mock()
@classmethod
def __getattr__(cls, name):
if name in ('__file__', '__path__'):
return '/dev/null'
elif name[0] == name[0].upper():
mockType = type(name, (), {})
mockType.__module__ = __name__
return mockType
else:
return Mock()
MOCK_MODULES = ['sip', 'PyQt5', 'PyQt5.QtGui', 'PyQt5.QtCore', 'PyQt5.QtWidgets']
for mod_name in MOCK_MODULES:
sys.modules[mod_name] = Mock()
产量
File ".../geoptics/guis/qt/main.py", line 59, in <module>
app = QCoreApplication.instance()
AttributeError: type object 'QCoreApplication' has no attribute 'instance'
应该可以将app
定义/检索内容从模块级别移动到函数体,而不是在模块导入时执行。
autodoc_mock_imports
autodoc_mock_imports = ['sip', 'PyQt5', 'PyQt5.QtGui', 'PyQt5.QtCore', 'PyQt5.QtWidgets']
<{1>}中的,与第2次尝试中一样,但是多个继承被装饰器替换。这些更改在此pull request中进行了描述。
现在错误是
conf.py
因为定义术语的地理位置类geoptics.guis.qt.handles.LineHandle.reset_move:1:term not in glossary: move restrictions
已被sphinx嘲笑,其文档丢失。
以下相关问题留下的评论:
答案 0 :(得分:0)
autodoc_mock_imports
已fixed in sphinx-1.7.5。
在docs/conf.py
中添加以下行:
autodoc_mock_imports = ['sip', 'PyQt5', 'PyQt5.QtGui', 'PyQt5.QtCore', 'PyQt5.QtWidgets']
然后,使用单行创建docs / requirements.txt
sphinx>=1.7.5
并在readthedocs项目中声明docs/requirements.txt
admin>advanced settings>Requirements file
。
令人高兴的是,这并未绕过setup.py,它只是添加了sphinx-1.7.5版本的要求。
