ckan - CKAN 开发安装问题：AttributeError：“模块”对象没有属性“css/main.debug.css”

Question

我已经完成了 CKAN 开发安装，并且在我的 development.ini 文件中使用 debug = true 运行。在访问 localhost:5000 时，我收到一个错误，其终点是错误：

AttributeError: 'module' object has no attribute 'css/main.debug.css'

由 lib/helpers.py 中的调用引起：

r = getattr(fanstatic_resources, resource)

知道我做错了什么以及我能做些什么来解决这个错误。

Answer 1

您需要从CKAN 源代码中less的目录运行脚本来构建文件。有这方面的一些文档，但它还没有与其余的 CKAN 文档集成（即在任何地方都没有指向它的链接，我们有一张票可以解决这个问题）。binmain.debug.css

这适用于 Ubuntu 12.04，您可能需要在执行此操作时激活 virtualenv：

sudo apt-get install nodejs npm
npm install less nodewatch
./bin/less # Assuming you're in your ckan dir e.g. `~/pyenv/src/ckan`

现在重新启动paster serve development.ini命令，它应该可以工作。

一般来说，每当运行 CKAN 2.0 进行开发时，您应该：

• 在你debug = True的ini文件中有
• 一直./bin/less在终端运行

Answer 2

请注意apt-get install nodejsinstallsnodejs而不是nodein /usr/bin，至少在 Ubuntu 12.10 中（我没有检查其他发行版）。这会引发错误，因为两者都ckan/bin/less在ckan/node_modules/less/bin/lessc调用 node. 所以要么在 /usr/bin 中创建一个软链接，要么修改脚本 ( #!/usr/bin/env nodejs)。

Answer 3

我在安装软件包时遇到了一些错误。以下是不耐烦的解决方案（根据官方 CKAN 文档）：

cp /usr/lib/ckan/default/src/ckan/ckan/public/base/css/main.css /usr/lib/ckan/default/src/ckan/ckan/public/base/css/main.debug.css

我正在使用 ubuntu 12.04 并遇到了一些问题

遵循肖恩的回答并运行后出现此错误

npm install less nodewatch

并得到这个错误：

找到另一个线程来解释这一点并提供执行的解决方案

npm config set registry http://registry.npmjs.org/

但是，在运行上述命令后，我收到此错误：

似乎版本不兼容，或者这可能是 node 和 node.js 的问题？
