`Manifest file is invalid` when installing my chrome extension?
I got this error too when I updated my extension. I think it happens sometimes when your extension is propagating to various servers. I came and looked at this thread and then went back to the store and tried again and it was fine.
I finally fixed this problem, it's just because my develop folder's path contains Chinese characters, moved it to a English path can solve this.
I had the same problem. The zip-file was accepted in the developer dashboard, but I got an error message saying that my manifest-file was invalid when installing from the webstore.
No Chineese characters on my end, it seemed like the problem was with character encoding.
I saved the manifest.json-file as ANSI - not UTF8 - and the package was accepted by the chrome webstore.
