Django-pipeline invalid syntax - django-pipeline

Question

I am trying to setup django-pipeline in my test project, however, I am running into a bug which doesn't have an obvious solution. Here is the pipeline configure in the settings.py
PIPELINE = {
'PIPELINE_ENABLED': True,
'COMPILERS': ('pipeline_browserify.compiler.BrowserifyCompiler', ),
'CSS_COMPRESSOR': 'pipeline.compressors.NoopCompressor',
'JS_COMPRESSOR': 'pipeline.compressors.uglifyjs.UglifyJSCompressor',
'STYLESHEETS': {
# 'animelist_css': {
# 'source_filenames': ( 'animelist/css/style.css', ),
# 'output_filename': 'animelist/css/animelist_css.css',
# }
},
'JAVASCRIPT': {
# 'animelist_js': {
# 'source_filenames': (
# 'animelist/js/bower_components/jquery/dist/jquery.min.js',
# 'animelist/js/bower_components/react/JSXTransformer.js',
# 'animelist/js/bower_components/react/react-with-addons.js',
# 'animelist/js/app.browserify.js',
# ),
# 'output_filename': 'animelist/js/animelist_js.js',
# }
}
}
As you can see from the configuration, this setting will allow collectstatic to run without any problem. However, collectstatic will fail if I were to uncomment those lines. The error is shown below
You have requested to collect static files at the destination
location as specified in your settings:
/var/www/anime/static
This will overwrite existing files!
Are you sure you want to do this?
Type 'yes' to continue, or 'no' to cancel: yes

Help is greatly appreciated.

Answer 1

Apparently, the error is the result of installing futures backport in pip3. Simply uninstall futures packages in your pip3.
