Django项目路径中的Unicode字符

Question

我在 Mac.

上使用 Django 1.7.3

我已经在以下路径中创建了一个 Django 项目：

/Users/cheng/百度云同步盘/Dev/django/testproject/

(项目名为'testproject')

我在加载模板文件时遇到问题：

/Users/cheng/百度云同步盘/Dev/django/testproject/
                                  -> vis
                                        -> templates
                                                 -> vis
                                                       -> index.html

（我的应用名称叫'vis'）

当我打右边URL时，我得到：

UnicodeEncodeError at /vis/
'ascii' codec can't encode characters in position 13-18: ordinal not in range(128)

Python Path:        ['/Users/cheng/\xe7\x99\xbe\xe5\xba\xa6\xe4\xba\x91\xe5\x90\x8c\xe6\xad\xa5\xe7\x9b\x98/Dev/django/testproject' ...

Unicode error hint

The string that could not be encoded/decoded was: heng/百度云同步盘/Dev/

如您所见，路径“百度云同步盘”的unicode部分已被ascii编码为“\xe7\x99\xbe\xe5\xba\xa6\xe4\xba\x91\xe5\x90\x8c\xe6\xad\xa5\xe7\x9b\x98”。

除了将项目移动到非 unicode 目录之外，还有什么方法可以解决这个问题吗？

谢谢！

更新：我正在使用 python 2.7.9。完整堆栈跟踪：

Answer 1

File "/usr/local/lib/python2.7/site-packages/django/template/loaders/app_directories.py" in calculate_app_template_dirs
  27.                 template_dir = template_dir.decode(fs_encoding)

这似乎是 Django 模板加载器中的错误。

它正在尝试 .decode 一个已经是 Unicode 的字符串，导致隐式 .encode 到默认编码，在您的情况下是 ASCII，因此它无法对中文进行编码。有问题的字符串是模块文件路径，来自AppConfig.path，定义为Unicode字符串。

我建议提交一个针对 Django 的错误（例如“模板加载器因默认编码中不可编码的路径而失败”）。与此同时，您可以尝试通过在您的 sitecustomize.py 中将默认编码设置为 utf-8 来解决它，或者仅从路径为全 ASCII 的目录中将您的应用设置为运行。
