python - Django 项目路径中的 Unicode 字符

Question

我在 Mac 上使用 Django 1.7.3。

我在以下路径中创建了一个 Django 项目:

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

(该项目称为“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

(我的应用程序名称称为“vis”)

当我点击正确的 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/

可以看到，“百度云同步盘”路径的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!

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 模板加载器中的一个错误。

它正在尝试.decode一个已经是Unicode的字符串，导致隐式.encode为默认编码，在您的情况下是ASCII，所以它不能对中文进行编码。有问题的字符串是一个模块文件路径，它来自AppConfig.path，它被定义为一个Unicode字符串。

我建议针对 Django 提交一个错误(例如“模板加载器因默认编码中路径不可编码而失败”)。同时，您可以尝试通过在 sitecustomize.py 中将默认编码设置为 utf-8 来解决此问题，或者仅从路径为的目录运行您的应用程序全 ASCII。
