I'm a new chrome extension developer, and I was going through the Chrome tutorial on making a "Hello World" extension, here's my code:
{
"name": "My First Extension",
"version": "1.0",
"manifest_version": 2,
"description": "The first extension that I made.",
"browser_action": {
"default_icon": "icon.png"
},
"permissions": [
"http://api.flickr.com/"
]
}
When I went to load the unpacked extension it said the manifest file was missing or unreadable. Yes I have the image in a folder with it and it is correctly named manifest.json
This question is related to
google-chrome-extension
My problem was slightly different.
By default Eclipse saved my manifest.json as an ANSI encoded text file.
Solution:
If you are downloading samples from developer.chrome.com its possible that your actual folder is contained in a folder with the same name and this is creating a problem. For example your extracted sample extension named tabCapture will lool like this:
C:\Users\...\tabCapture\tabCapture
I also encountered this issue.
My problem was that I renamed the folder my extension was in, so all I had to do was delete and reload the extension.
Thought this might help some people out there.
Mine also was funny. While copypasting " manifest.json" from the tutorial, i also managed to copy a leading space. Couldn't get why it's not finding it.
In my case it was the problem of building the extension, I was pointing at an extension src (with manifest and everything) but without a build.
If you run into this scenario run
npm i
then
npm build
Kindly check whether you have installed right version of ChromeDriver or not . In my case , installing correct version helped.
Some permissions issue for default sample.
I wanted to see how it works, I am creating the first extension, so I downloaded a simpler one.
Downloaded 'Typed URL History' sample from
https://developer.chrome.com/extensions/examples/api/history/showHistory.zip
which can be found at
https://developer.chrome.com/extensions/samples
this worked great, hope it helps
