Why can't this chrome extension be installed?

Question

I have a couple very short + simple extensions that I can't install to chrome. I am given the following error about the 'manifest version', so I assume that the problem is that it is outdated, I haven't any experience in chrome extensions/javascript so I couldn't fix them myself as I would normally try to do, these were written for me by a friend a while back.

Could someone let me know how I should correct these files?

Error:

The 'manifest_version' key must be present and set to 2 (without quotes). See developer.chrome.com/extensions/manifestVersion.html for details.

Many thanks for any help

Answer 1

The error message is self-explanatory:

The 'manifest_version' key must be present and set to 2 (without quotes). See developer.chrome.com/extensions/manifestVersion.html for details.

The referenced documentation provides a very clear example at the top of the page:

{
  ...,
  "manifest_version": 2,
  ...
}

These dots indicate that parts of the manifest file were omitted for the sake of the example. You have to edit your manifest.json file, and insert "manifest_version": 2 somewhere in the file.

For example, in your case, you can add a line before the "version" key and put the "manifest_version": 2 declaration over there.

   ...
   
   "version": "1.0"
}

Note that there's a comma at the end of the line. In the JSON data format, every name/value pair is separated by a comma.

Answer 2

add in you 'manifest.json':

'manifest_version': 2

example:

{
    "name": "name your extension",
    "version": "1.0",
    "description": "description your building",
    "manifest_version": 2,
    "browser_action":{
       "default_icon": "icon777.png",
       "popup": "body.html"
    }
 }
