terser is undefined?

[devanshbatra04]

• Operating System: Ubuntu 16.04
• Node Version: v9.10.0
• NPM Version: v5.6.0
• webpack Version: v4
• terser-webpack-plugin Version: v1.1.0

Expected Behavior

This should not happen, the build should work as expected.

Actual Behavior

I try to run the angular build, this set of errors props up, pretty sure it's related to terser. I looked up the dist/minify.js apparantly _terser2 is undefined

How Do We Reproduce?

I'm getting the same issue. Here is a sample Travis CI run.

Appears to be a duplicate of #67 and #66.
