在zc.buildout中安裝私有python lib時出現錯誤的Marshall數據

爲我的其中一個項目安裝依賴項時，出現錯誤的編組數據錯誤。如果我們使用標準virtualenv進行安裝，它可以正常工作而不會出錯。在zc.buildout中安裝私有python lib時出現錯誤的Marshall數據

這裏是我的zc.buildout的一部分（目前導致該錯誤被註釋掉的部分）：

[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

有誰知道什麼可能會導致這問題以及如何解決問題。我們目前正在通過手動下載和包含軟件包來管理這個（正如你可以在buildout配置中看到的那樣），這並不理想。

什麼是完整的回溯錯誤？ '糟糕的marshall數據'聽起來像你在庫中有'.pyc'文件，這些文件是用於錯誤的Python版本或者被破壞的。 – 2014-10-10 10:20:32

添加了回溯。這就是說我不認爲python版本可能是原因。我會檢查 – Andre 2014-10-10 10:41:58

zip安全掃描失敗;嘗試加載'.pyc'文件，該文件使用'marshall'來存儲代碼對象和常量值，並且加載'.pyc'文件是失敗的。由於pip不支持雞蛋，因此您不會看到這個問題。否則不清楚爲什麼你的蛋中的一個.pyc文件無法加載。 – 2014-10-10 10:54:46

我認爲這可能與我們用來混淆被認爲是專有文件的方式有關。直到3個月前，我們希望隱藏的模塊以原始pyc文件形式傳輸，後綴指示其python版本，例如rml2pdf_27.pyc，rml2pdf_33.pyc等。

現在我們傳輸一個包含嵌入編譯後的代碼作爲數據，所以它現在不應該被打包商看到。這個改變發生在3.1.9創建之後。

謝謝！升級到3.1.38解決了這個問題:) – Andre 2014-10-10 11:59:38
