我正在尝试将我的PWA网站转换为Android apk文件以在Google Play商店中分发，但无法使用Bubblewrap或PWABuilder生成apk文件。我的 PWA 的网址是 https://www.stephengarside.co.uk .
我正在运行以下命令行气泡包装init --manifest "https://www.stephengarside.co.uk/manifest.json">，我得到的错误是：
错误 https://www.stephengarside.co.uk/manifest.json 原因处的 JSON 响应正文无效：位置 0 处的 JSON 中存在意外令牌
我的清单.json文件是：

我的PWA工作正常，我能够安装它并且在Windows或Android设备上没有错误。谷歌灯塔也将其验证为PWA。 我在PWABuilder上遇到类似的错误。
我尝试将文件重命名为 manifest.webmanfest，并已使用 https://manifest-validator.appspot.com/验证了清单。
由于我的机器上已经安装了该应用程序的服务wroker，因此我尝试取消注册以确保不会从缓存中带来任何内容，并且还尝试以隐身方式运行pwabuilder。
任何帮助将不胜感激。
事实证明，这与我的Json文件的内容无关，而是编码。我下载了记事本++并使用UTF8编码保存了manifest.json文件，这解决了问题。您可以在本文中阅读更多内容 https://www.stephengarside.co.uk/blog/how-to-create-a-pwa-umbraco-website/
