拒绝推送，无法编译 Node.js 应用程序

Question

我有一个Angular 2 项目，我打算部署到Heroko，所以我配置了package.json 文件，并在项目的根目录中创建了一个server.js 文件，当我尝试推送项目时，它给了我一个parse error，并说它期望在第 13 行第 3 列有另一个键值对。我已经验证了文件中相应的第 13 行第 3 列，但我没有发现任何奇怪的地方。也许我什么都没看到=/。下面我将留下“package.json”，以及一个带有错误消息的屏幕。

错误信息

Answer 1

您的 JSON 文件格式错误。您可能想使用 JSON 验证器来检查它：https://jsonlint.com/

删除"postinstall": "ng build --aot -prod",和"npm": "5.6.0",末尾的,。

Answer 2

我建议你尝试npm cache clean 并重新安装你的包。
