在服务器上，对于磁盘优化，我们不安装C编译器， 这是问题所在：
我想安装＆＃39;刺激＆＃39;带有 buildout 2.3.1 的python包， spur正在使用需要C编译器的pycrypto。
为避免编译，我在服务器（Suse 11SP2）上安装了rpm python-pycrypto（python-pycrypto-2.6-31.7.x86_64.rpm）。我可以通过冻结＆＃39; pip冻结来查看。已安装pycrypto：
pip freeze
lxml==2.1.2
mod-python==3.3.1
Numeric==24.2
numpy==1.3.0
pycrypto==2.6
pywbem==0.7.0
PyXML==0.8.4
然而，当我开始构建时，它仍然试图使用不存在的C编译器构建pycrypto。
所以我在buildout.cfg中添加了include-site-packages = true和allowed-eggs-from-site-packages = pycrypto，但它们没有被考虑在内。 我也尝试过：
python bootstrap.py --allow-site-packages
bin/buildout
但这也没有帮助。
我可以做些什么来避免buildout编译已经从rpm编译和安装的软件包？
这是buildout.cfg
[buildout]
newest = false
extensions = gp.vcsdevelop
develop-dir = src
parts = eggs tests wsgi
include-site-packages = true
allowed-eggs-from-site-packages = pycrypto
eggs =

和日志：

答案 0 :(得分：4)
我找到了解决方法：
我刚刚在egg-egg目录中创建了一个egg-link文件：
$ cat develop-eggs/pycrypto.egg-link
/usr/lib64/python2.6/site-packages
答案 1 :(得分：0)
我没有证据证明zc.buildout＆gt; 1.7.1支持include-site-packages，也不支持allowed-eggs-from-site-packages。
在我的本地计算机上，我搜索了以下zc.buildout版本中提到的功能：
在https://pypi.python.org/pypi/zc.buildout/1.7.1上查看自述文件。这些功能是在zc.buildout 1.5.0附近引入的。支持这些功能的最后一个版本是1.7.1。
他们使用zc.buildout 2.0.0进行了某种重新启动......
引用changlog，版本2.0.0：
这是一个向后不兼容的buildout版本，它试图纠正buildout 1中的错误。
Buildout不再试图提供与系统Python安装的完全或部分隔离。如果你想要隔离，可以使用buildout和virtualenv，或者使用干净的Python构建开始。
在您的情况下，这意味着，如果您想使用这些功能，则需要使用zc.buildout 1.7.1。
同样重要的是，不可能同时使用这两个选项。使用allowed-eggs-from-site-packages (only specific packages)或include-site-packages。
我假设你正在使用boostrap.py版本1：http://downloads.buildout.org/1/bootstrap.py
此版本不支持' - allow-site-packages'选项，因为它打算与zc.buildout 1.x一起使用，它处理这种情况（或至少1.5.x）。
嗯，在这次建队历史的短暂旅行之后，我想以下两点可以解决你的问题：
--allow-site-packages选项。然后python bootstrap.py --allow-site-packages按预期工作。
