Use Django_compressor ES6Compiler under Windows

I tried to run a Django App I developed under Linux on an Windows setup. The Application starts, but when I enter a page with a template which uses the compressor like this ("index.js" imports npm packages):

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

.. I get this Error:

My Settings Look like:

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

I tried different things, including reinstall of all dependencies, reinstalling all npm packages.. nothing worked until now.

It looks like you're using the ES6Compiler from compressor_toolkit.

That one is using the export command, which is only available on Linux. You'll need to ask the compressor_toolkit project to add windows support, or to build that yourself and make a PR, or to use linux :)
