我有问题将React Native App从Expo sdk 21升级到Expo sdk 26 .
我已按照以下步骤操作：
1）在app.json中，将sdkVersion更改为“26.0.0”2）在package.json中，更改这些依赖项：
-
react-native to“https://github.com/expo/react-native/archive/sdk-26.0.0.tar.gz”
-
世博会"^26.0.0"
-
作出反应（"16.3.0-alpha.1" - 此确切版本）
-
react-navigation to "1.5.8"
以前，我使用的是：
-
expo ^ 21.0.2
-
react-navigation ^ 1.0.0-beta.21“
-
react ": " ^ 16.0.0-alpha.12“，
-
react-native ": " ^ 0.48.4“
现在我得到这个错误，我不知道从哪里开始搜索或调试..任何想法？
这是完全依赖：
"dependencies": {
"@expo/vector-icons": "^5.2.0",
"expo": "^21.0.2",
"install": "^0.10.1",
"moment": "^2.19.1",

}
关于我如何获得线路，图书馆或者造成这种冲突的东西的任何想法？
亲切的问候

好吧，这个错误很难调试，但问题是我的代码中存在循环依赖 .
"Super expression must either be null or a function.."消息是一种ES6 babel方式，告诉您导入/循环依赖项中存在错误 .因此，在解决了很多工作要做之后，正如@Michael Cheng所说，很多库确实在SDK21和SDK26之间做了很多改变 .
