关于Plone 4.1.3及4.0.7不能在Ubuntu 11.10下安装的问题


问题如下：
64位Ubuntu 11.10，安装了所有的升级和补丁，显卡驱动也更新了，从Plone.org下载的Universal installation pack 4.1.3在解压缩之后，运行如下命令：
./install.sh standalone --password=123
先是那个python编译不能通过，说是什么zip code的问题LookupError: Unknown Encoding: zip
然后又是zlib的问题，用了--libz=no参数依然不行
然后又是libxml的问题，用了apt-get install libxml依然不行；
然后又是buildout运行不正常导致退出的问题。到这里死活过不去，让人感觉这一版本的Plone简直是漏洞百出，问题太多了。

其实根本问题就是Plone自带的Python编译没有通过的问题。解决了这个问题后面的都不是问题了。
在google.com搜索LookupError: UnknowEncoding: zip这个错误信息，在http://stackoverflow.com网站上有一条解答，现摘录如下：

Its an issue with the Python disutils and the new multilib setup of natty. I ran into the same issue trying to get sqlite support in Python built from source.

You can hack around it in the detect modules section of the setup.py

http://bugs.python.org/issue9762

Edit:

To work around it, change lib_dirs in the python setup.py (around line 408) to this (for an x86_64 machine):

lib_dirs = self.compiler.library_dirs + [
    '/lib64', '/usr/lib64',
    '/lib', '/usr/lib', '/usr/lib/x86_64-linux-gnu',
    ]

(the /usr/lib/x86_64-linux-gnu is missing)

在Plone/package下找到python-2.6.7-tar.bz2，将他解压缩，找到里面的setup.py文件，浏览到408行附近，然后按照上面所说的，加上'/usr/lib/x86_64-linux-gnu',这些红色的内容。别忘了逗号。然后保存这个setup.py文件。

下面还需要将解压缩出来的文件重新压缩成python-2.6.7-tar.bz2，再次运行install.sh standalone，Plone的安装就能成功了。

PS：上面所说的natty，指的是Ubuntu 11.04。

最后，附上成功安装的Console输出。
