我正在学习使用Mastering Plone为plone（4.3.10）创建自定义产品，当我安装使用mrbob创建的新包时，我会在section停止。
Here是我的扩建（我取消了由trainnig通知的行）
我的目录：
jafar@plonedev:~/training/buildout$ pwd
/home/jafar/training/buildout
jafar@plonedev:~/training/buildout$ ls -l src
drwxrwxr-x 4 jafar jafar 4096 Ago 22 16:15 ploneconf.site
drwxrwxr-x 4 jafar jafar 4096 Ago 22 15:13 ploneconf.site_sneak
[UPDATE]
我在训练中又做了一遍，并且buildout是http://paster.org/m/lnpaxn，使用这个命令创建了包：
$ cd src
$ ../bin/mrbob -O ploneconf.site bobtemplates:plone_addon
在回答问题之后......我运行了buildout，这是我的输出：
(py27) jafar@plonedev:~/training/buildout/src$ ls
ploneconf.site ploneconf.site_sneak
(py27) jafar@plonedev:~/training/buildout/src$ cd ..
(py27) jafar@plonedev:~/training/buildout$ vim buildout.cfg

记住......
我遵循这个培训： https://training.plone.org/4/eggs1.html#including-the-egg-in-plone
[更新2]
我认为问题出在buildout.cfg中，在SOURCE部分我们有这个
[sources]
ploneconf.site = fs ploneconf.site full-path=${buildout:directory}/src/ploneconf.site
我尝试将$ {buildout：directory}替换为完整路径
/home/jafar/training/buildout/src/ploneconf.site
然而，它没有用！
