无法安装 Plone 附加组件

Question

我正在尝试安装plone.app.多语言，据我所见，安装进展顺利，但该插件不会出现在我网站的"插件"列表中。

cmd:

C:Plone43>binbuildout.exe
Getting distribution for 'lxml==2.3.6'.
Building lxml version 2.3.6.
Building without Cython.
ERROR: 'xslt-config' is not recognized as an internal or external command,
operable program or batch file.
** make sure the development packages of libxml2 and libxslt are installed **
Using build configuration of libxslt
error: Setup script exited with error: Unable to find vcvarsall.bat
An error occurred when trying to install lxml 2.3.6. Look above this message for
 any errors that were output by easy_install.

lxml安装失败，是否有可能是原因？

我在buildout.cfg上尝试了几个不同的配置，这是我最近的一个（只涉及鸡蛋的部分）：

[buildout]
...
eggs = 
   Pillow
   Plone
   plone.app.iterate
   plone.app.openid
   Products.CMFPlacefulWorkflow
   plone.app.multilingual [archetypes]
   plone.app.multilingual [dexterity]
zcml =
    plone.app.multilingual

感谢所有的帮助！我已经被这件事困扰了一段时间，我认为这是最后的手段。。。

正如Martijn Pieters所指出的，问题是lxml安装不正确。他发布了一个问题的链接，解释了如何解决这个问题：

LXML无法在Plone 4.3 64位（MS Windows）上安装
