在 Windows 下使用 Django_compressor ES6Compiler

Question

我尝试运行我在 Linux 下开发的 Django 应用程序 Windows 设置。应用程序启动，但是当我进入一个带有模板的页面时，该模板使用这样的压缩器（"index.js" 导入 npm 包）：

{% load static %}
{% load compress %}
<html>
        ...
    <body>
      ...
      {% compress js %}
      <script type="module" src="{% static 'index.js' %}"></script>
      {% endcompress %}
    </body>
</html>

..我得到这个错误：

compressor.exception.FilterError: 'export' is not recognized as an internal or external command

我的设置看起来像：

STATIC_URL = '/static/'
STATICFILES_DIRS = [ "cs_viewer/static", ]
STATIC_ROOT="cs_viewer/static"

INSTALLED_APPS += (
    'compressor',
    'compressor_toolkit',
)
STATICFILES_FINDERS = (
    'compressor.finders.CompressorFinder',
)
COMPRESS_CSS_FILTERS = [
    'compressor.filters.css_default.CssAbsoluteFilter',
    'compressor.filters.cssmin.CSSMinFilter',
    'compressor.filters.template.TemplateFilter'
]
COMPRESS_JS_FILTERS = [
    'compressor.filters.jsmin.JSMinFilter',
]
COMPRESS_PRECOMPILERS = (
    ('module', 'compressor_toolkit.precompilers.ES6Compiler'),
    ('css', 'compressor_toolkit.precompilers.SCSSCompiler'),
)
COMPRESS_ENABLED = True

我尝试了不同的方法，包括重新安装所有依赖项、重新安装所有 npm 包……直到现在都没有任何效果。

您似乎在使用 ES6Compiler from compressor_toolkit。

那个 is using the export command，仅在 Linux 上可用。您需要请求 compressor_toolkit 项目添加 windows 支持，或者自己构建并进行 PR，或者使用 linux :)

在 Windows 下使用 Django_compressor ES6Compiler

Use Django_compressor ES6Compiler under Windows

django

npm

django-compressor
