Python需要哪些依赖项才能避免UnicodeDecodeError？

如何解决Python需要哪些依赖项才能避免UnicodeDecodeError？

| 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。

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
