collectfiles failes for pipeline / yUglify: The system cannot find the path specified


I've been trying to get django-pipeline to work to combine and minify my css and js assets. I don't seem to be able to sort the following issue out. When I run:

python manage.py collectstatic --noinput

I get an error:

pipeline.exceptions.CompressorError: The system cannot find the path specified.

Do I maybe need to install some additional packages? If so, how?

My settings for django-pipeline:

STATICFILES_STORAGE = 'pipeline.storage.PipelineCachedStorage'
STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'pipeline.finders.PipelineFinder',
)

PIPELINE_CSS = {
    'testme': {
        'source_filenames': {
            'static/surveys/css/main.css',
        },
        'output_filename': 'css/testme.css',
    },
}

PIPELINE_JS = {
    'testmejs': {
        'source_filenames': {
            'surveys/js/gklib.js',
        },
        'output_filename': 'surveys/js/testmejs.css',
    },
}

PIPELINE_ENABLED = True

This is the complete output:

UPDATE

I've tried it again using another compressor:

PIPELINE_CSS_COMPRESSOR = 'pipeline.compressors.csstidy.CSSTidyCompressor'

This gives the exact same result, what could I be doing wrong?

UPDATE 2

If I set the compressors to None everything works, i.e. the files get combined and placed in the static files folder. They are also served correctly.

PIPELINE_CSS_COMPRESSOR = None
PIPELINE_JS_COMPRESSOR = None

So it must be something either in accessing or using the compressors. I'm running on Windows.

UPDATE 3

I've added some print() commands to init.py in /site-packages/pipeline/compressors/

class SubProcessCompressor(CompressorBase):
    def execute_command(self, command, content):
        import subprocess
        print("Command: " + command)

The command is: /usr/bin/env/ yuglify --type=css --terminal Which can (probably?) never work on Windows.

I've then tried to deploy it to AWS Elastic Beanstalk, but I get an error then as well:

INFO: Environment update is starting.
INFO: Deploying new version to instance(s).
ERROR: [Instance: i-75dc5e91 Module: AWSEBAutoScalingGroup ConfigSet: null] Command failed on instance. Return code: 1 Output: [CMD-AppDeploy/AppDeployStage0/EbExtensionPostBuild] command failed with error code 1: Error occurred during build: Command 01_collectstatic failed.

INFO: New application version was deployed to running EC2 instances.
ERROR: Update environment operation is complete, but with errors. For more information, see troubleshooting documentation.
ERROR: Update environment operation is complete, but with errors. For more information, see troubleshooting documentation.

I know it's possible to manually set the location of the compressors bin, but where to set it for Elastic Beanstalk?

Any suggestions how to sort this out?


Solution

  • I've fixed it by adding commands to the .ebextensions/app.config file:

    # these commands run before the application and web server are
    # set up and the application version file is extracted
    commands:
      01_node_install:
        # run this command from /tmp directory
        cwd: /tmp
        # don't run the command if node is already installed (file /usr/bin/node exists)
        test: '[ ! -f /usr/bin/node ] && echo "node not installed"'
        # install from epel repository
        # flag -y for no-interaction installation
        command: 'yum install -y nodejs npm --enablerepo=epel'
        command: 'npm -g install yuglify'
    

    Based these commands on what I found on http://qpleple.com/install-nodejs-on-elastic-beanstalk/
