我正在使用Plone collective's Python buildout。它构建了各种版本的Python，包括2.6和2.7。
出于某种原因，当我尝试使用2.7进行发布时，我收到此错误：
$ /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。一切都按预期工作。
这通常会让我相信编译Python的环境出现了问题（Mac OS X），但在这种情况下，2.6和2.7都是在同一环境中编译的，但有一个是有效的，有一个不是。
这里可能出现什么问题？我能看到/检查什么来解决这个问题？
答案 0 :(得分：1)
以下是我认为的不同之处：两个python安装中的docutils版本。
在docutils包上仍有不断的工作，该项目定期将当前的Subversion HEAD作为快照发布。 Python 2.7回溯中的行号似乎与最新的快照相匹配（根据2010年9月1日发布的下载标题）。
我有理由相信Python 2.6 site-packages目录与Python 2.7安装目录不同。
执行命令
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，然后让Python 2.7在导入时重新编译它们，或者使用compileall.py脚本：
python-2.7/bin/python python-2.7/lib/python2.7/compileall.py lib/python2.7/site-packages/docutils
答案 1 :(得分：0)
这种情况正在发生，因为Python从不是ascii的文件中读取一些数据。 Python上的默认编码是ascii，ascii只支持7位字符（＆lt; 128）。
您有几种方法可以解决此错误：
gcc -c -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -I./Include -DPy_BUILD_CORE -o Modules/python.o Modules/python.c
cc1: error: unrecognized command line option "-Wno-long-double"
