博览会用户-确保您的app.json sdk版本和包。Json的博览会版本是(可能相等)彼此兼容。

I've never seen this error before, but whenever I can't get Xcode and React-Native to play well together, I do a couple of things. Check what version of Xcode I'm working with. If it needs to be updated, I update it. Then clearing watchman and the cache are the second place I go. I don't use the reset cache command. It always says that I need to verify the cache, so I skip that (you can do it though, I just get confused). I use rm -rf $TMPDIR/react-* to get rid of any cached builds. If that doesn't work, I try to build the app in Xcode, then work my way from there, to build it with react-native run-ios. With this error message, it seems you might start by trying to build it with Xcode. Hope that helps...let me know your progress with it. Good luck! (Also, you could update to RN 0.51 as another attempt to get your versions synced.)
编辑您的包。Json为你的javascript版本
"react-native": "^0.50.1",
后运行
npm install
对我来说,这是由于包的依赖项部分的反应本机版本。json文件。它是:
"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "~0.55.0"
}
我把它改成:
"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "0.52.0"
}
现在它工作得很好。
如果你用create-react-native-app创建react-native-app。你应该有一个app.json (expo)。还有一个包裹。Json文件,检查世博版本是否匹配并相应更改。例如,在我的案例中,问题是在app.json文件中,我有一个25.0.0版本的expo sdkVersion属性,我将其更改为23.0.0,一切正常工作。
package.json:
"dependencies": {
"expo": "^23.0.4",
"react": "16.0.0",
"react-native": "^0.50.4"
}
app.json:
{
"expo": {
"sdkVersion": "23.0.0" // before was 25.0.0
}
}
这是我对它所做的:
关闭所有终端并再次运行构建。
你可能忘记从另一个项目关闭nodejs终端,而他们碰巧安装了不同的react版本。
因此,从nodejs服务器获取的代码与本机代码冲突。
