使用狮身人面像生成烧瓶扩展文档

Question

我正在尝试为flask-restful生成文档，这是对烧瓶的扩展，它使生成RESTful API变得更加容易。我的最后一个目标是使用doc2dash生成破折号文档测试。

但是，在完成此操作之前，我需要使用sphinx生成所需的html。在我的尝试中，我克隆了烧瓶-restful项目，并尝试使用make html从它的docs文件夹生成文档。但是，我收到了17条警告，结果的文档是不完整的。这是回溯：

从结果中可以看出，问题在于文档中将烧瓶-restful扩展引用为ask flask.ext.restful。但是，由于该文档的生成需要源代码，因此sphinx无法找到它，因此引发和ImportError，因为该模块称为flask_restful。这棵树看起来像：

.
├── docs
│   ├── _build
│   ├── _static
│   ├── _templates
│   └── _themes
│       ├── flask
│       │   └── static
│       └── flask_small
│           └── static
├── examples
├── flask_restful  <---------- Not flask.ext.restful
│   ├── representations
│   └── utils
├── scripts
└── tests

所以，问题是我如何让sphinx理解flask.ext.restful实际上是flask_restful

在遵循安蒂的建议之后，更新如下：

Answer 1

如果您想从SCM安装一个模块(git、hg等签出)，并且不费太大力气就安装它，那么：

1. 创建一个虚拟环境
2. 将工作副本签出到任何您想要的地方(不一定在项目文件夹中)，
3. 在virtualenv中以开发模式将签出模块链接到 python setup.py开发 如获支持，或 python setup.py安装 如果需要安装。

在这些步骤之后，flask_restful应该作为flask.ext.restful被导入。
