我使用https://github.com/plone/plonedev.vagrant在 Windows 上设置了 Plone 4.3 开发环境。我一直在尝试为我的安装添加 Dexterity 支持，但遇到了问题。

我采取的步骤如下：

  1. 将 zopeskel.dexterity 和 plone.app.dexterity [relations, grok] 添加到我的 buildout.cfg 的 [eggs] 部分

  2. 将 ZopeSkel <= 2.99 添加到 buildout.cfg 的 [versions] 部分

我重新运行 buildout 并尝试在前台模式下启动服务器，但得到这个回溯：

ImportError: No module named script.templates

编辑：我忘了提到 buildout.cfg 扩展了 base.cfg，其中包含以下内容：

[zopeskel]
# installs paster and Zopeskel
recipe = zc.recipe.egg
eggs =
    ZopeSkel
    Paste
    PasteDeploy
    PasteScript
    ${buildout:eggs}

我刚刚尝试明确添加PasteScript到 buildout.cfg 中的 [eggs] 部分。运行 buildout 并尝试启动服务器后，我得到了不同的回溯：

ImportError: No module named util.template

这是我的 Python 路径的问题吗？bin/zopepy然后我跑了import paste;print paste.__file__，输出是：

/vagrant/plone/src/hello.world/PasteScript-1.7.5-py2.7.egg/paste/__init__.pyc

Paste-1.7.5.1 egg 目录确实包含一个 paste/util/template.py 文件，但看起来解释器找不到它。

您不需要将 Dexterity 添加到 Plone 4.3，它已经包含：

正如zopeskel.dexterityPyPI 页面上所记录的，您也需要包含PasteScript鸡蛋；回溯显示它丢失了：

[zopeskel]
recipe = zc.recipe.egg
eggs =
   ZopeSkel < 3.0dev
   Paste
   PasteDeploy
   PasteScript
   zopeskel.dexterity
   ${buildout:eggs}

你可能做的工作比你需要做的要多得多。plonedev.vagrant 套件预装了 zopeskel 和 zopeskel.dexterity。看看这个成绩单：

steve@lumpy:~/plonedev_vagrant$ vagrant ssh

vagrant@vagrant-ubuntu-precise-32:~/Plone/zinstance/src$ ~/Plone/zinstance/bin/zopeskel dexterity

dexterity: A Dexterity-based product

这有一点神奇：由于 plonedev.vagrant 工具包符号链接 src 目录的方式，您不能 cd 到它并使用“../bin/zopeskel”。这就是使用“~/Plone/zinstance/bin/zopeskel dexterity”命令的原因。

我们应该记录这种奇怪的情况，或者找到一种方法来避免它。
