Answer 1

Just delete the "browserlist" (text file) from project directory, and also delete "browserlist.cmd" file. (it worked for me)

Answer 2

I was facing same issue on windows 10 with node version 10.0.0 and angular cli version 1.7.4. Now removed browserlists file and browserslist.cmd in project directory. It works for me :).

Answer 3

See: https://github.com/angular/angular-cli/issues/3938#issuecomment-272633128

(Changing filename "browserlist" to "00_browserslist" in your project folder, fixed it for me)
