Answer 1

You're missing a comma(,) here "laravel/framework": "5.3.*",
If invalid json error occurred you can check which line creates error by validating your json code here. Just paste your code and it will highlight the line(s) for you.

Answer 2

You may try to change the line where it gives an error to something like this.
"laravelcollective/html": "^5.2",
ANd to make it easier. Add a comma at the end of the
"laravel/framework": "5.3.*"
Hope it could help.

Update your laravel/framework dependency to 5.3.* in your composer.json file.
You should also upgrade your symfony/css-selector and symfony/dom-crawler dependencies to 3.1.* in the require-dev section of your composer.json file.
