Question

在为我的某个项目安装依赖项时，我遇到了错误的编组数据错误。如果我们使用标准的virtualenv安装，它可以正常工作而没有错误。

这是我的zc.buildout的一部分（目前导致错误的部分被注释掉）：

[buildout]
versions = versions
extensions = mr.developer
unzip = true
include-site-packages = false

# FIXME
# Attempting to install from here via buildout raises a bad marshal data error
# I should note that this errors does _not_ occur when we install in a
# clean virtual environment. It only happens in buildout.
# find-links = https://<myuser>:<mypass>@www.reportlab.com/pypi/simple/rlextra/

# Temporary solution, we included the package manually and will add it as
# a develop egg, then in the "django" part further down, we need to
# include the package in the extra-paths.
develop = ${buildout:directory}/libs/rlextra-3.1.9

An error occured when trying to install rlextra 3.1.9. Look above this message for any errors that were output by easy_install.

是否有人知道可能导致此问题的原因以及如何解决此问题。我们目前通过手动下载并包含软件包来管理它（正如您在buildout配置中看到的那样），这是不理想的。

我认为这可能与我们过去混淆被视为专有文件的方式有关。直到3个月前，我们希望隐藏的模块作为原始pyc文件传输，后缀表示其python版本，例如rml2pdf_27.pyc，rml2pdf_33.pyc等。

现在我们传输一个包含嵌入式编译代码作为数据的python文件，因此它现在不应该对包装者可见。这种变化发生在3.1.9创建之后。
