Question

我开始学习Plone开发非常令人沮丧。我想为Plone 4开发一个基于灵巧的内容类型。我是一位经验丰富的python开发人员，对Zope和Grok有一些了解，对于buildout来说是一个新手。也就是说，我读过Martin Aspeli撰写的“Professional Plone 4 Development”，但书中的一些版本信息似乎已经过时了。

使用buildout我能够启动并运行Plone实例。 ZopeSkel已安装，但是当我尝试创建一个新包时，我收到如下错误：

**************************************************************************
**  Your new package supports local commands.  To access them, change
**  directories into the 'src' directory inside your new package.
**  From there, you will be able to run the command `paster add
**  --list` to see the local commands available for this package.
**************************************************************************


ERROR: No egg-info directory found (looked in ./domma.voucher/./domma.voucher.egg-info, ./domma.voucher/bootstrap.py/domma.voucher.egg-info, ./domma.voucher/bootstrap.pyo/domma.voucher.egg-info, ./domma.voucher/buildout.cfg/domma.voucher.egg-info, ./domma.voucher/CHANGES.txt/domma.voucher.egg-info, ./domma.voucher/CONTRIBUTORS.txt/domma.voucher.egg-info, ./domma.voucher/docs/domma.voucher.egg-info, ./domma.voucher/domma/domma.voucher.egg-info, ./domma.voucher/README.txt/domma.voucher.egg-info, ./domma.voucher/setup.cfg/domma.voucher.egg-info, ./domma.voucher/setup.py/domma.voucher.egg-info, ./domma.voucher/src/domma.voucher.egg-info)

如果我尝试从给定目录中运行paster，它告诉我，“add”命令不知道。我尝试了不同版本的ZopeSkel并尝试了原始的plone模板以及zopeskel.dexterity。输出稍有不同，具体取决于版本和模板，但结果保持不变。

显然，Plone开发似乎对版本更改非常敏感，这使得旧文档变得毫无用处。 http://plone.org/products/dexterity/documentation/manual/developer-manual告诉我，它已于1114年前更新过。

有人能给我一个起点，为Plone 4开发一个非常简单的灵巧内容类型吗？

Answer 1

对于它的价值，虽然有一些新版本的包，但专业Plone 4开发是最新的Plone 4.1。我建议你使用它，并从它的示例代码开始。在你知道自己有一个有效的起点之前，不要试图任意升级，你应该没事。

Answer 2

http://pigeonflight.blogspot.com/2012/01/dexterity-development-quickstart-using.html提供了一个很好的快速入门。最新的Dexterity文档位于http://dexterity-developer-manual.readthedocs.org/en/latest/index.html。是的，这是一个移动目标，文档方面，而不是由于敏捷，这是稳定和生产，但主要是因为Zopeskel目前正处于重大发展/现代化。对不起。

Answer 3

来自[https://github.com/collective/templer.plone/blob/master/README.txt] [1]

Templer不能在同一个buildout中与旧的ZopeSkel共存，也不能与Python virtualenv共存。

否则在尝试创建包::

时会遇到以下错误

  IOError: No egg-info directory found (looked in ./mycompany.content/./mycompany.content.egg-info, ....

Templer是ZopeSkel（版本3）的最新版本。我不确定你有什么版本的ZopeSkel，或者你是否在buildout或virtualenv中安装了混合版本。但ZopeSkel的冲突安装很可能是罪魁祸首。

我会从头开始重新创建vitualenv并通过buildout安装最新版本的ZopeSkel 2。 ZopeSkel 3或Templer仍在大力发展，并非所有模板都已迁移。

Answer 4

我能够使用此buildout创建一个新的具有新Dexterity内容类型的Plone 4.1.4站点。这不应该是官方的答案，但将配置粘贴到像pastebin这样的易变服务不是永久文档的选项。
