Answer 1

We've faced this issue on Angular Cli 1.7.4 at times. Initially we've got

Cannot read property 'config' of null
TypeError: Cannot read property 'config' of null

And fixing this lead to the above issue.

We've removed package-lock.json

npm remove webpack

npm cache clean --force

You can also remove your node_modules folder. And then clean the cache. re-installed angular cli:

npm install @angular/cli@1.7.4

And then you can do npm install again, just to make sure if everything is installed.

Then run

npm ls --depth 0

To make sure if all your node_modules are in sync with each other. If there are any dependency mismatching, this is the opportunity for us to figure out.

Finally run npm start/ng serve. it should fix everything.

This is out cheat code that we'll follow if we run into any issues with cli, before we dig deeper. 95% of times it fixes all the issues.

Hope that helps.
