我将Angular更新到了版本8，但遇到了一个小问题.当我通过离子服务启动应用程序

I updated my Angular to version 8, and I have run into a small problem. when I start the app with ionic serve

 Error: Can't resolve all parameters for setupPlatform: (?, [object 
 Object], [object Object]).

我试图回滚到旧版本，仍然遇到相同的问题.我有另一个离子应用程序，它可以与我的配置一起使用.

I have tried to rollback to an older version, still get the same problem. I have another ionic app and it works with the config I have.

我不知道是什么setupPlatform，它不在我编写的代码中.我认为这是某些插件的一部分，我使用VS Code进行了搜索-在setupPlatform上没有找到匹配项.我有点卡住，在寻找解决方案的搜索中，我没有发现任何人遇到类似的问题.在这方面需要一些帮助.

I have no idea what setupPlatform, it's not in the code i written. I assume is part of some add on plugin, I did a search using VS Code - did not get a match on setupPlatform. I'm a bit stuck and in my searches to find a solution, I have not found anyone had a similar issue. Need some help on this one.

谢谢.

推荐答案

我收到了相同的错误消息.我在Chrome开发人员工具中使用了Inspect来跟踪它在NgModules中运行时在"PLTCONFIG"上出现hasunknowdependency = true错误.缺少的参数是setupPlatform()的"doc"参数.然后，我跟踪到不再从此处引用的平台浏览器问题导出的文档":

I was receiving the same error message. I used Inspect with Chrome Developer Tools to track it to a hasunknowdependency = true error on "PLTCONFIG" as it runs through the NgModules. The missing parameter is the "doc" parameter of setupPlatform(). I then tracked that to the "DOCUMENT" no longer exported from platform-browser issue referenced here: "export 'DOCUMENT' was not found in '@angular/platform-browser'. After I made the changes the error disappeared. I hope this helps.
