Question

我在buildout中包含一个使用C扩展的egg（jsonlib）。在pypi上，存在预编译的blob。但它与我的环境不兼容：我收到undefined symbol: PyUnicodeUCS4_FromEncodedObject错误。我知道这与编译时和运行时的不同环境有关。要解决它，buildout应该编译包而不是使用预构建的包。

无论在pypi上找到哪些预编译的egg文件，我如何告诉buildout编译一个包（所有包也没关系）？

你去了：

[buildout]
parts = getit

# used to show which download was fetched
download-cache = .

[getit]
recipe = zc.recipe.egg
# this is the first key: ignore using the pypi index
index = .
# this is the second key: provide a direct link to the sdist
find-links = https://pypi.python.org/packages/source/h/hachoir-core/hachoir-core-1.3.3.tar.gz
eggs = hachoir-core==1.3.3

并且仅针对某些使用条件部分的操作系统（免责声明，我写了这篇文章）和最新版本的buildout：

[buildout]
parts = getit
download-cache = .

[getit: macosx]
recipe = zc.recipe.egg
index = .
find-links = https://pypi.python.org/packages/source/h/hachoir-core/hachoir-core-1.3.3.tar.gz
eggs = hachoir-core==1.3.3

[getit: not macosx]
recipe = zc.recipe.egg
# use pypi alright
eggs = hachoir-core==1.3.3

运行之后，检查目录，它将有一份获取的存档副本进行验证：那里没有预制的鸡蛋;）

如何告诉buildout忽略二进制分发并从源代码构建？
