我正在使用Plone 集体的 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 发布时，我收到此错误：

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（Mac OS X）有问题，但在这种情况下，2.6 和 2.7 都是在同一个环境中编译的，但一个可以工作，一个不能。

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？

这是我认为不同的地方：两个 python 安装中的 docutils 版本。

关于 docutils 包的工作仍在持续进行中，并且该项目会定期发布当前的 Subversion HEAD 作为快照。您的 Python 2.7 回溯中的行号似乎与最新快照匹配（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 站点包目录与 Python 2.7 安装中的目录不同。

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，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 从非 ascii 文件中读取了一些数据。Python 上的默认编码是ascii并且 ascii 只支持 7 位字符 (<128)。

你有几个选项来纠正这个错误：

  • 告诉python为此文件使用正确的编码
  • 以二进制形式读取文件并使用字节而不是字符串（不太可能）
  • 将 python 默认编码更改为使用 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
cc1: error: unrecognized command line option "-Wno-long-double"
