我有一个非常令人沮丧的开始学习 Plone 开发。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 有一定的了解，对于构建来说相当陌生。也就是说，我读了 Martin Aspeli 的“Professional Plone 4 Development”，但书中的相当多的版本信息似乎已经过时了。

使用 buildout，我能够启动并运行一个 Plone 实例。ZopeSkel 已安装，但当我尝试创建新包时，出现如下错误：

**************************************************************************
**  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 paste，它会告诉我，命令“add”是未知的。我尝试了不同版本的 ZopeSkel，并尝试了原始 plone 模板和 zopeskel.dexterity。输出根据版本和模板略有变化，但结果保持不变。

Obvisouly Plone 开发似乎对版本更改非常敏感，这使得旧文档非常无用。http://plone.org/products/dexterity/documentation/manual/developer-manual告诉我，它上次更新是在 1114 年前。

有人可以给我一个起点，为 Plone 4 开发一个非常简单的灵巧内容类型，它真的有效吗？

值得一提的是，虽然某些软件包有一些较新版本，但 Professional Plone 4 Development 是 Plone 4.1 的最新版本。我建议你使用它，并从它的示例代码开始。在你知道你有一个工作的起点之前，不要试图随意升级东西，你应该没问题。

http://pigeonflight.blogspot.com/2012/01/dexterity-development-quickstart-using.html提供了一个不错的快速入门。最新的 Dexterity 文档位于http://dexterity-developer-manual.readthedocs.org/en/latest/index.html。是的，从文档角度来看，这有点移动目标，与其说是因为 Dexterity 是稳定的而且在生产中，但主要是因为 Zopeskel 目前正在大力开发/现代化。对于那个很抱歉。

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

Templer 不能与旧版 ZopeSkel 或 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。我不确定您拥有什么版本的 ZopeSkel，或者您是否在 buildout 或 virtualenv 中安装了混合版本。但是 ZopeSkel 的安装冲突可能是罪魁祸首。

我将从头开始并重新创建 vitualenv，然后通过 buildout 安装最新版本的 ZopeSkel 2。ZopeSkel 3 或 Templer 仍在大量开发中，并非所有模板都已迁移。

我能够使用这个构建创建一个具有新的敏捷内容类型的新 Plone 4.1.4 站点。这不应该是官方的回答，但是将配置粘贴到像 pastebin 这样的易失性服务并不是永久文档的选项。
