Python需要哪些依赖项来避免UnicodeDecodeError？

我在用电脑。它构建了各种Python版本，包括2.6和2.7

出于某种原因，当我尝试使用2.7版本发布时，会出现以下错误：

$ /Users/aclark/Developer/collective/python/python-2.7/bin/mkrelease -T -d local

没有独角兽。一切正常

这通常会让我相信编译Python的环境（Mac OS X）出了问题，但在本例中，2.6和2.7都是在同一个环境中编译的，但一个工作，一个不工作

---

这里可能出了什么问题？我可以寻找/检查什么来解决这个问题呢？

这是因为Python从非ascii文件读取一些数据。Python上的默认编码是

ascii

，ascii只支持7位字符（我认为不同之处在于：两种Python安装中的docutils版本

docutils包仍在不断地工作，该项目定期将当前Subversion头作为快照发布。Python 2.7回溯中的行号似乎与最新快照相匹配（根据下载的标题，该快照于2010年9月1日发布）

我确信Python2.6站点包目录与Python2.7安装中的目录不同

运行：

diff-ur python-2.6/lib/python2.6/site-packages/docutils python-2.7/lib/python2.7/site-packages/docutils

为了确认这一点，如果我是对的，只需将2.6树中的版本复制到2.7树，并在导入时让Python 2.7重新编译它们，或者使用

compileall.py

脚本：

python-2.7/bin/python-2.7/lib/python2.7/compileall.py lib/python2.7/site-packages/docutils

谢谢！这通常是答案，但在这种情况下，这是一个更微妙的问题，即docutils安装，据我所知，我无法执行您提出的建议。@a你能提供一个我可以运行的测试用例吗？在最坏的情况下，我们必须提交一个bug或补丁docutils。这会变得更奇怪。你说得对t、 这是docutils安装（！），但我也发现：easy_install-2.7 docutils==0.5修复了这个问题，这是好的。但是：pip install docutils（即安装最新的，0.7）也修复了它。换句话说，easy_install似乎没有正确安装最新版本，而pip却正确安装了。谁能解释这个问题呢？：-）在任何情况下，除非我错了，否则pip在这里胜过easy_install。直接下载的链接。我的猜测是easyinstall会在其他版本之前找到快照版本，而pip会更好地约束该版本。
