bug: @angular/cli version 1.6.4 causes webpack build to fail

[mo2menelzeiny]

@angular/cli 1.6.4 removed the InsertConcatAssetsWebpackPlugin, and added ScriptsWebpackPlugin
I tried to make it work however I haven't succeeded on re-implementing the external scripts feature.

plugins.push(new InsertConcatAssetsWebpackPlugin([
                 ^
TypeError: InsertConcatAssetsWebpackPlugin is not a constructor

UPDATE:

it's becasue the new cli version doesn't having this class, I just resolved this by replacing the InsertConcatAssetsWebpackPlugin with the new ScriptsWebpackPlugin.

const {BaseHrefWebpackPlugin, NamedLazyChunksWebpackPlugin, ScriptsWebpackPlugin} = require('@angular/cli/plugins/webpack');

now in the implementation replace

plugins.push(new InsertConcatAssetsWebpackPlugin([
      "scripts"
    ]));

with the new imported ScriptsWebpackPlugin implementation

plugins.push(new ScriptsWebpackPlugin({
      name: "scripts",
      sourceMap: true,
      scripts: scripts
    }));

I'm running 1.6.4 and had the same issue. After updating to ng-cli 1.6.7 though I'm now getting Error: Cannot find module '@ngtools/webpack' when I run npm start. Are these potentially connected issues?

EDIT: Scratch my issue. I had an environment variable messed up and yarn didn't install the dev dependencies as I expected.
