I googled, https://github.com/angular/angular-cli/issues/8598 got this, still, i didn't get a solution.

Answer 1

npm install -g npm-check-updates

This command is to see the package difference and not to fix any issue., I`ll suggest you to delete your node_modules folder and execute this command

 ncu -u 

and

npm install --save

to update your package.json. Once done with it, try with

ng build --prod

Answer 2

Please update "@angular/cli" to "1.7.3"

Step 1: npm remove @angular/cli Step 2: npm cache clean --force Step 3: npm install -g @angular/cli@1.7.3

Still stuck then update your package.json with

"@angular/cli": "1.7.3" and run npm install

Tested and working for me

Answer 3

I resolved by doing RND. And finally got solution by removing deprecated css in my project.

For example .section{color:#ddd;} .section{font-size:14px} this is deprecated css and I changed to .section{color:#ddd; font-size:14px} .section{color:#ddd; font-size:14px}

And I customisd my bootstrap css for example I copied css which are all usefull to my project to my style.css.

It's worked for me.
