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

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

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

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 :).
