it said all is right, but the error is still existed

Could you teach me where is the problem?

Start removing one line at a time until you find the line with the problem. — Matt Runion, Sep 09 '18 at 12:37
nope, the `JSON` syntax error originates from http://127.0.0.1:8000/cebula/1Sun/setting response... obviously the wrong configuration `JSON` had been posted. good there was the stack-trace, which I'd almost found a little long, at first. — Martin Zeitler, Sep 09 '18 at 12:43
Looks like the issue is at cebula_react\node_modules\@babel\core\lib\config\files\package.js:57 — Ioan, Sep 09 '18 at 13:27
@MartinZeitler oh thanks, the problem is in response part not in package.json itself! Could I ask one more question? I'm trouble in dealing with https://stackoverflow.com/questions/52237855/support-for-the-experimental-syntax-classproperties-isnt-currently-enabled?noredirect=1#comment91424857_52237855 — 1Sun, Sep 09 '18 at 13:27
