未安装'expo'/'react-native'/'react-native-render-html'/'react-navigation‘依赖项

Question

watchman watch-del-all && rm -rf node_modules/ && yarn cache clean && yarn install

我多次尝试重新安装这些依赖项，但是每次我运行时

exp start -c

我有以下警告

01:22:43 [exp] Warning: 'expo' dependency is not installed.
01:22:43 [exp] Warning: 'react-native' dependency is not installed.
01:22:43 [exp] Warning: 'react-native-render-html' dependency is not installed.

这是我的package.json

我的项目已经弹出了世博工具包，我正在遵循弹出屏幕的指示。在弹出之前，它运行得很好，但现在我不能让代码运行。

我用Xcode构建了我的代码，它成功了。我可以运行模拟器，但我什么也看不见，只有白色的屏幕。期望我有一个红色的旗帜在底部与那些“解散”“重新加载”“复制”“更多的信息”。我试着复制，但我的剪贴板上没有任何东西。

我弹出的回复是: 1. npm运行弹出2.选择expoKit 3.等待它弹出4.更新的世博sdk到26 5.将本机响应更改为世博叉6.荚安装

我错过了什么吗？

Answer 1

案子结了。

我得把纱线更新到最新版本，npm就不行了。

在把纱线升级到1.6之后，现在一切都很好。
