I had same problem, I use webpack with less loader, I needed to add javascript option in less loader config:
{
test: /\.less$/,
use: [{
loader: "style-loader"
}, {
loader: "css-loader"
}, {
loader: "less-loader",
options: {
javascriptEnabled: true
}
}]
}
I found in the sourcecode of less compiler: https://github.com/less/less.js/blob/3.x/bin/lessc
that they parse js less option in this way:
case 'js':
options.javascriptEnabled = true;
break;
case 'no-js':
console.error('The "--no-js" argument is deprecated, as inline JavaScript ' +
'is disabled by default. Use "--js" to enable inline JavaScript (not recommended).');
break;
So you should probably use ‘–js’ in a static compilation ( command line ) or ‘javascriptEnabled: true’ in a dynamic compilation ( like webpack loader ) to enable javascript.
