Python Pybabel使用jinja2生成空罐文件

我用的是烧瓶，烧瓶巴贝尔和金贾2。我正在尝试生成.pot文件。到目前为止我就是这么做的

我的babel.cfg如下所示：

[python: **.py]

[jinja2: **.html]
encoding = utf-8
extensions=jinja2.ext.autoescape,jinja2.ext.with_

# Babel init
babel = Babel(app)
app.config['BABEL_DEFAULT_LOCALE'] = 'en'

...
<div class="news-wrapper">
    <p class="quote">{{ gettext('Hey there') }}</p>
    <p class="quote">{% trans %}Trying 42{% endtrans %}</p>
    <p class="quote">{{ _('Maybe like this?') }}</p>
</div>
...

pybabel extract -F babel.cfg -o messages.pot .

extracting messages from templates/homepage.html (extensions="jinja2.ext.autoescape,jinja2.ext.with_", encoding="utf-8")

我的应用程序是这样的：

[python: **.py]

[jinja2: **.html]
encoding = utf-8
extensions=jinja2.ext.autoescape,jinja2.ext.with_

# Babel init
babel = Babel(app)
app.config['BABEL_DEFAULT_LOCALE'] = 'en'

...
<div class="news-wrapper">
    <p class="quote">{{ gettext('Hey there') }}</p>
    <p class="quote">{% trans %}Trying 42{% endtrans %}</p>
    <p class="quote">{{ _('Maybe like this?') }}</p>
</div>
...

pybabel extract -F babel.cfg -o messages.pot .

在我的模板目录中，我有homepage.html:

[python: **.py]

[jinja2: **.html]
encoding = utf-8
extensions=jinja2.ext.autoescape,jinja2.ext.with_

# Babel init
babel = Babel(app)
app.config['BABEL_DEFAULT_LOCALE'] = 'en'

...
<div class="news-wrapper">
    <p class="quote">{{ gettext('Hey there') }}</p>
    <p class="quote">{% trans %}Trying 42{% endtrans %}</p>
    <p class="quote">{{ _('Maybe like this?') }}</p>
</div>
...

pybabel extract -F babel.cfg -o messages.pot .

extracting messages from templates/homepage.html (extensions="jinja2.ext.autoescape,jinja2.ext.with_", encoding="utf-8")

其中一个输出行是：

[python: **.py]

[jinja2: **.html]
encoding = utf-8
extensions=jinja2.ext.autoescape,jinja2.ext.with_

# Babel init
babel = Babel(app)
app.config['BABEL_DEFAULT_LOCALE'] = 'en'

...
<div class="news-wrapper">
    <p class="quote">{{ gettext('Hey there') }}</p>
    <p class="quote">{% trans %}Trying 42{% endtrans %}</p>
    <p class="quote">{{ _('Maybe like this?') }}</p>
</div>
...

pybabel extract -F babel.cfg -o messages.pot .

并生成包含以下内容的messages.pot文件：

[python: **.py]

[jinja2: **.html]
encoding = utf-8
extensions=jinja2.ext.autoescape,jinja2.ext.with_

# Babel init
babel = Babel(app)
app.config['BABEL_DEFAULT_LOCALE'] = 'en'

...
<div class="news-wrapper">
    <p class="quote">{{ gettext('Hey there') }}</p>
    <p class="quote">{% trans %}Trying 42{% endtrans %}</p>
    <p class="quote">{{ _('Maybe like this?') }}</p>
</div>
...

pybabel extract -F babel.cfg -o messages.pot .

该文件没有我的翻译

我没有收到任何错误或警告，pybabel只是在jinja2文件中找不到

gettext

变体但是当我在.py文件中使用

gettext

时，它工作得很好

---

我错过了什么吗？

花了几个小时想办法，我找到了解决办法，如果有人需要，我会发帖寻求帮助

我在模板中安装了Flask资产，显然，如果您有它，您需要添加到您的

babel.cfg

：

extensions=jinja2.ext.autoescape,jinja2.ext.with_,webassets.ext.jinja2.AssetsExtension

从文件中：

否则，babel将不会从任何包含资产标记的模板中提取字符串

---

我将执行一个pull请求，检查您是否安装了Flask资产和Flask Babel，并且您没有添加正确的扩展，它将向您发出警告-我认为开发人员应该得到一些错误/警告

对于不使用公认答案中提到的资产扩展的其他人，问题可能在于

babel.cfg

文件本身

对我来说，问题在于我的

babel.cfg

文件，我从这个文件中获取了这个文件

后来，当我从这里的问题开始使用babel.cfg文件时，一切都很顺利

为了记录在案，这里是为我工作的

babel.cfg

文件

[python: **.py]
[jinja2: **.html]
encoding = utf-8
extensions=jinja2.ext.autoescape,jinja2.ext.with_

---

我遇到了同样的问题，在我的例子中，问题是指定输入文件，即在哪里查找标记为翻译的字符串的文件

当我按照各种教程（例如）中的建议运行

pybabel extract-F babel.cfg-o messages.pot

时，我得到了

pybabel:error:没有指定输入文件或目录

错误

最终对我有效的命令是：

pybabel extract -F babel.cfg -o messages.pot --input-dirs=.

---

我遇到了类似的问题：

输入：

pybabel extract-F babel.cfg-k\u l-o messages.pot

输出：

用法：pybabel extract[选项]

pybabel:错误：未指定输入文件或目录

我的解决方案是在输入命令后添加两个空格和一个句点

pybabel extract-F babel.cfg-k\u l-o messages.pot.

希望这有帮助

更新：

我的

babel.cfg

文件是：

[python:*.py]
[jinja2:*.html]
extensions=jinja2.ext.autoescape，jinja2.ext.with

在您的

babel.cfg

中设置

silent=False

将有助于查明问题：问题是，这应该是默认设置：（感谢您指出webassets jinja2扩展！唷，这是一个模糊的错误——感谢您发布的修复，工作非常完美。
