When you call ng generate, it reads the angular.json file in your project. I had a similar issue, except mine was "Unexpected token /". I had commented out portions of the json file. The CLI did not like the my use of "//", so I had to remove the commented out sections, and it started working fine after that. So comb through your angular.json file, you probably have some malformed code in it.

@briangullo you're right. Thanks!
My JSON had this issue (the comma after "error", last line...).

   "en": {
          "aot": true,
          "outputPath": "dist/myapp-en/",
          "i18nFile": "src/locale/messages.en.xlf",
          "i18nFormat": "xlf",
          "i18nLocale": "en",
          "i18nMissingTranslation": "error", // REMOVE COMMA HERE
        }

@briangullo same problem here, thanks.

Unexpected token ] in JSON at position 434

I pasted my angular.json file into a json validator and it clean. not sure where to look now.

Use
These Command

1. ng update
2. ng update@ angular/cli

I received this error as well. "Unexpected token }" or "]" probably means you put a comma after the last element. The error message doesnt provide the file name or line number but I'm guessing position is characters from start of file. I just opened angular.json in vim and the culprit was highlighted.

Also, come on JSON specification, is that comma hurting anyone? ;)

delete package-lock.json

JSON is malformed, you can easily spot the error at https://jsonlint.com/

In my case I had a trailing ',' after one of my style imports in angular.json
