bower-files | dynamically include your bower components | Build Tool library

So the problem I am facing is that some packages in my package.json file required node version greater than 10. So I have nvm package installed to manage node versions and when I do node -v it gives me this: v12.19.0. So if the node version is 12.19.0 then the error shouldn't come but I think this is a global version of node so when I do npm update, this comes up:

I know this has been asked many times before, but none of the answers helped me to solve my problem migrating gulp 3 to 4. We didn't necessarily have to upgrade to version 4 of gulp, but updating Node.js from 10 to 12 forced us to do so, since Node.js 12 doesn't support gulp 3 anymore. Here are just 2 of files in our build process, I think that it should be enough to understand what the problem is from these files alone, but I can add the other files if need be. And I have also removed the contents of most functions for brevity.

As bower slowly 'shuts down' I am finding it very difficult to migrate from bower to npm. I managed to get the DEV packages downloaded but I cannot seem to figure out how to use equivalent to 'main-bower-files' for npm. I found something similar 'main-npm-files' but there is no way to use the "override" method, similar to how bower uses, to point which files should be copied.

Can someone please guide me on how I can do this? If you need me to paste my package.json here let me know.

I am using es6 syntax in my angular JS project but it throws error when run gulp build, search over github and So but some saying this is error due to gulp uglify while some say this is babel issue and other say ng-annonate issue.

node -v : 8.4.0

npm -v : 5.3.0

babel --version : 6.26.0 (babel-core 6.26.0)

I had a number of issues which I fixed by using the run recomendations in the npm audit dialog. However I cant fix one even after running

I am trying to transpile my ES6 js to ES5 js. When I visit the https://babeljs.io/repl webpage to test out what babel should output for the preset option es2015 it outputs JavaScript that is different than what gulp-babel outputs.

I'm trying to build environment using sudo gulp that raised this error:

Here is to minify html file inside gulp as follow

Using our gulp script, we want to create different compiled & minified css files for vendor (via bower, see screenshot) and custom styles. Our task for the vendor styles does not work as expected, though. We expected it to iterate through the bower_components, grab the css files, concatenate them, minify them and save the generated vendor.min.css to dist/styles. Said vendor.min.css is not generated, however. We tried commenting some of the .pipe() commands in the return statement and suspect that it might have something to do with the concat() function.
