Javascript 清单不是有效的JSON。第21行，第1列，语法错误。无法加载清单。？

最后，还需要一个括号来“关闭”json

{
    "name": "Extension",
    "version": "2.0.0",
    "manifest_version": 4,
    "description": "This is a Test.",
    "homepage_url": "https://example.com",
    "icons": {
        "16": "icons/16.png",
        "48": "icons/48.png",
        "128": "icons/128.png"
    },
    "options_page": "src/options/options.html",
    "background": {
        "scripts": ["src/test0/test1.js", "test2.js", "main_compiled.js"],
        "matches": [""],
        "js": ["bubble_compiled.js"],
        "css": ["bubble_gss.css"],
        "all_frames": true
    }

我不确定，我所做的错误源代码也是关于可读性的。使用正确的格式，您很容易看到错误。见@anastasios selmanis的答案
