python - 在 zc.buildout 中安装私有(private) python lib 时 Marshall 数据错误

Question

在为我的一个项目安装依赖项时，我遇到了错误的编码数据错误。如果我们使用标准 virtualenv 安装，它可以正常工作，不会出现错误。

这是我的 zc.buildout 的一部分(目前导致错误的部分已被注释掉):

[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.

有谁知道可能导致此问题的原因以及如何解决它。我们目前通过手动下载并包含软件包(如您在构建配置中看到的)来管理此问题，这并不理想。

我认为这可能与我们用来混淆被认为是专有的文件的方式有关。直到 3 个月前，我们希望隐藏的模块都以原始 pyc 文件的形式传输，并带有表示其 python 版本的后缀，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，因此打包者现在不应该看到它。该更改发生在 3.1.9 创建后。
