Python需要哪些依赖项才能避免UnicodeDecodeError？

问题描述

| 我正在使用Plone集体的Python构建。它构建了各种版本的Python，包括2.6和2.7。 由于某些原因，当我尝试使用2.7发布时，出现此错误： 
$ /Users/aclark/Developer/collective/python/python-2.7/bin/mkrelease -T -d local

UnicodeDecodeError: \'ascii\' codec can\'t decode byte 0xe2 in position 32: ordinal not in range(128)
register Failed
但是，如果我使用Python 2.6： 
$ /Users/aclark/Developer/collective/python/python-2.6/bin/mkrelease -T -d local
没有UnicodeDecodeError。一切正常。 通常，这会使我相信Python的编译环境（Mac OS X）出了点问题，但是在这种情况下，2.6和2.7都是在同一环境中编译的，但有一个可行，而一个没有。 这里可能出什么问题了？我可以寻找/检查些什么来解决这个问题？     

解决方法

        我认为这是不同的：两种python安装中的docutils版本。 在docutils软件包上仍需要不断进行工作，并且该项目会定期将当前的Subversion HEAD作为快照发布。 Python 2.7追溯中的行号似乎与最新的快照匹配（根据下载的标题，该快照于2010年9月1日发布）。 我有理由确定，Python 2.6 site-packages目录与Python 2.7安装目录不同。 跑： 
diff -ur python-2.6/lib/python2.6/site-packages/docutils python-2.7/lib/python2.7/site-packages/docutils
确认这一点。如果我是对的，只需将2.6树中的版本复制到2.7树中，并让Python 2.7在导入时重新编译它们，或使用
compileall.py
脚本： 
python-2.7/bin/python python-2.7/lib/python2.7/compileall.py lib/python2.7/site-packages/docutils
    ,        发生这种情况是因为Python从不是ascii的文件中读取了一些数据。 Python上的默认编码为
ascii
，而ascii确实仅支持7位字符（<128）。 您可以通过以下几种方法来更正此错误： 告诉python为此文件使用正确的编码 将文件读取为二进制文件并使用字节而不是字符串（可能性较小） 更改python默认编码以使用utf-8（有点风险） 顺便说一句，我试图在我的系统上运行bin / buildout，但是它失败了（后来），因为它使用了一些编译器不支持的命令行选项。
