我正在尝试使用命令行工具用 Babel 翻译 jinja2/coffin 模板。问题是函数 babel_extract 卡在 {% url %} 或 {% csrf_token %} 等棺材标签上。

首先，为了检测问题，我修改了 jinja.ext.babel_extract 并在渲染时在异常上添加了“print e”。

try:
    node = environment.parse(source)
    tokens = list(environment.lex(environment.preprocess(source)))
except TemplateSyntaxError, e:
    # skip templates with syntax errors
    print e
    return

当我使用 Babel 运行 extract 方法时，它会打印出以下错误：

Encountered unknown tag 'url'. Jinja was looking for the following tags: 'endblock'. The innermost block that needs to be closed is 'block'. extracting messages from templates/contact.html (encoding="utf-8")

然后我编辑了我的 babel 配置以添加棺材库。我还设置了环境变量以将我的 django 项目添加到我的 python 路径并将 django 设置模块设置为我的 settings.py。

[python: src/**.py]

[jinja2: templates/**.html]
encoding = utf-8
extensions = coffin.template.Library

[extractors]
jinja2 = jinja2.ext:babel_extract

现在，当我运行 extract 方法时，会发生此错误：

extracting messages from templates/brands.html (extensions="coffin.template.Library", encoding="utf-8") Traceback (most recent call last): File "/usr/local/bin/pybabel", line 9, in <module> load_entry_point('Babel==0.9.6', 'console_scripts', 'pybabel')() File "/Library/Python/2.7/site-packages/Babel-0.9.6-py2.7.egg/babel/messages/frontend.py", line 1107, in main return CommandLineInterface().run(sys.argv) File "/Library/Python/2.7/site-packages/Babel-0.9.6-py2.7.egg/babel/messages/frontend.py", line 651, in run return getattr(self, cmdname)(args[1:]) File "/Library/Python/2.7/site-packages/Babel-0.9.6-py2.7.egg/babel/messages/frontend.py", line 912, in extract for filename, lineno, message, comments in extracted: File "/Library/Python/2.7/site-packages/Babel-0.9.6-py2.7.egg/babel/messages/extract.py", line 171, in extract_from_dir strip_comment_tags): File "/Library/Python/2.7/site-packages/Babel-0.9.6-py2.7.egg/babel/messages/extract.py", line 201, in extract_from_file strip_comment_tags)) File "/Library/Python/2.7/site-packages/Babel-0.9.6-py2.7.egg/babel/messages/extract.py", line 275, in extract for lineno, funcname, messages, comments in results: File "/Library/Python/2.7/site-packages/jinja2/ext.py", line 588, in babel_extract auto_reload=False File "/Library/Python/2.7/site-packages/jinja2/environment.py", line 279, in __init__ self.extensions = load_extensions(self, extensions) File "/Library/Python/2.7/site-packages/jinja2/environment.py", line 76, in load_extensions result[extension.identifier] = extension(environment) TypeError: __init__() takes exactly 1 argument (2 given)
