SyntaxError: Unexpected end of JSON input

[marcobarbosa]

Hi,

I've started getting this error and could use some clues. It's probably related to my project but why would standardjs fail like this:

> <repo>@1.0.0 standard /Users/marcobarbosa/Repos/<repo>
> standard 'src/**/*.js'

standard: Unexpected linter output:

JSON input? Is it trying to read JSON files?

Using Node v6.92 and standard 8.6.0.

I also get this by running standard directly in the terminal (after installing it globally).

Do you have any ideas?

[LinusU]

Maybe your package.json is invalid?

[marcobarbosa]

@LinusU Thanks for the tip! I just double checked and it's valid JSON.

Also, here's a npm-debug.log running on node v6.1.0. There are no prestandard or poststandard tasks.

Note it mentions EventEmitter, is that related to my code or to some lib standard uses?

standard task in my package.json:

"standard": "standard 'src/**/*.js'",

Also tried ignoring JSON:

"standard": {
    "ignore": [
      "src/**/*.json"
    ]
  }

This issue is caused by an invalid cache file, which can happen if standard crashes or if you kill standard with Ctrl-C while it is running.

This was a bug in a dependency of standard, which is now fixed. For more information, see: eslint/eslint#7748

Thanks @feross !

i saw this issue is over here, but i am suffering about this issue as 'syntaxerror: unexpected end of json input' when i am trying to edit order. I had trying to realized the previous solutions. but i am not clear. anyone can explain easily to solve the issue. Opencart version is 2.0.3.1

[feross]

@smnayeem Sorry, you're posting on a completely different issue tracker that has nothing to do with OpenCart. Good luck figuring out your issue, though!

'SyntaxError: Unexpected end of JSON input' the same issue
