Windows Support / export FilterError

[FSE-DEV]

In Windows 10 environment a FilterError(err) in raised: "compressor.exception.FilterError: 'export' is not recognized".

Regarding the issue and answer here: https://stackoverflow.com/questions/55029689/use-django-compressor-es6compiler-under-windows - is Windows supported at all? If so, what cofigurations / adjustments are missing?

Thank you.

Hi, I need to know if this issue will be solved, I have the same problem with the es6compiles in windows.

Sorry, it's been awhile since I visited my project last time. Too much work to do on my job.

is Windows supported at all?

I have designed it to work on any platform where the underlying Node libraries work (I mean node-sass, less, etc).

But I have tested it only on Linux / macOS :)

Indeed, the problem is in the COMPRESS_ES6_COMPILER_CMD setting - its default value is for UNIX / Linux systems:

COMPRESS_ES6_COMPILER_CMD = 'export NODE_PATH="{paths}" && '
        '{browserify_bin} "{infile}" -o "{outfile}" '
        '-t [ "{node_modules}/babelify" --presets="{node_modules}/babel-preset-es2015" ]'

I'm not very familiar with Windows CMD way of setting the NODE_PATH env variable right in the command line.

If you will figure it out - just set your custom Django setting:

# settings.py
COMPRESS_ES6_COMPILER_CMD = '<set the NODE_PATH env var to {paths} somehow and call> '
        '{browserify_bin} "{infile}" -o "{outfile}" '
        '-t [ "{node_modules}/babelify" --presets="{node_modules}/babel-preset-es2015" ]'

If it's not possible through the CMD then it should be possible from Python:

os.environ["NODE_PATH"] = ...

But this would require a pull-request to this project.

And I'm really sorry but I'm still very busy at my main job, so I appreciate your help with the pull-request ;)

I am trying to get this to work on windows.

This is as close as i got

settings.py

COMPRESS_ES6_COMPILER_CMD = '$env:NODE_PATH="{paths}" && {browserify_bin} "{infile}" -o "{outfile}" -t [ "{node_modules}/babelify" --presets ["{node_modules}/@babel/preset-env"] ]'

(untitledgame) PS C:\Projects\untitledgame> python manage.py compress
CommandError: An error occurred during rendering game\index.html: The filename, directory name, or volume label syntax is incorrect.

game\index.html

    {% compress js %}
		{% include "game/parts/scripts_libs.html" %}
	{% endcompress %}

    {% compress js %}
        {% include "game/parts/scripts_game.html" %}
        <script src="{{ STATIC_URL }}custom/js/main-common.js" type="module"></script>
        <script src="{{ STATIC_URL }}custom/js/main-game.js" type="module"></script>
    {% endcompress %}

I have verified browserify and babel actually works by running a command directly. This command works:

.\node_modules\.bin\browserify ".\static\custom\js\main-game.js" -o bundle.js -t [ "./node_modules/babelify" --presets ["./node_modules/@babel/preset-env"] ]

if os.name == 'nt':
    COMPRESS_ES6_COMPILER_CMD = 'set NODE_PATH="{paths}" && {browserify_bin} "{infile}" -o "{outfile}" -t [ "{node_modules}\\babelify" --presets="{node_modules}\\babel-preset-es2015"]'
    COMPRESS_BROWSERIFY_BIN = 'node_modules\\.bin\\browserify'

This gets past an initial error, however ended up with a EPERM rename error, which seems to be related to the TemporaryNamedFile, using an absolute output file path avoids this, however Django can still not properly run the code
